5.1 General
The program permits the parameters of a defined storage area to be changed. The permissible range of each parameter will be checked whenever an entry is made and limited accordingly. A distinction is made between variable parameters (e.g maximum speed, direction of rotation or control parameters) and display parameters for indicating various operating values (e.g. current speed, current reference value, etc.). The following display will appear on starting the CPIK frequency inverter:
ThyssenKrupp Elevator System start Vxxx ThyssenKrupp Elevator CPIK 32 Vxxx
This display of the program number version will appear for 15 seconds only. Program version number to be quoted for any inquiries made to the factory. If one of the keys is operated during these 15 seconds, the display of the version number will be discontinued immediately and the selected function will be performed. If you wait for 15 seconds, the first available parameter will be displayed.
P 0 Reference value start delay 500 ms
The turn-on duration of the display lighting is set to two hours after the key was pressed last.
When a key is operated for the first time after turning off the lighting, the lighting will be turned on again, but this does not have any effect on the parameter function.
5.2 Operation
Parameter entry permits the following functions: 5.2.1 Display and change of parameters
The parameter number with a short description of the selected parameter is in the first line, the current value with its physical unit in the second line. A cursor appears below the parameter number.
The desired parameter number can now be selected with the keys “+“ and “-“. By advancing the cursor with the “cursor“ key, the selection can now proceed in steps of tens or hundreds.
P 5 P gain 8.0
By operating the “parameter“ key, the cursor will go to the numeric value and a change of the numeric value will be possible.
P 5 P gain 8.1
A stroke is below the least significant digit of the numeric value. This stroke marks that digit which will be changed by -1 by operating the “+“ key or by “-“. This marking will be shifted to the left by one position whenever the “cursor“ key is operated. This permits a quick change of the parameter throughout a wide range. If the “+“ or “-“ key is held depressed for longer than two seconds, the parameter value will be changed by +1 or –1 at intervals of 0.25 seconds.
Some parameters, as e.g. P7 language, do not have a number as value, but a selection from a list. P 7 Language
→ English
Here, too, the entry can be changed by operating the “+“ and “-“ keys.
The change of the parameter value will not become effective until the change is acknowledged by pressing the “parameter“ key !
5.2.2 Display parameters
The display parameters show operating parameters such as momentary speed of motor. Selection of desired parameter as described in chapter 5.2.1 Display and change of parameters.
P100 motor speed + 103.5 min-1
The displayed value – actual speed in this case – will be continually updated. 5.2.3 Save changed parameters to EPROM
Without saving data like this, parameter changes will be lost after powering off the CPIK device! The following display will appear after pressing the “save“ key:
Values to be saved? (+) = Yes, (-) = No
If the “save“ key has been pressed inadvertently, the saving operation can be stopped by pressing the “-“ key (No). All parameters will be saved to the EPROM by operating the “+“ key (Yes). The following information will be displayed while saving is in progress:
Data being saved Wait please
Never cut off the control voltage while saving is in progress. If this happens, check all parameters and correct them, if required.
5.2.4 All parameters as factory-set
This function permits the original values of all parameters to be restored at any time. Pressing the
“parameter“ key and simultaneously operating the “save“ key will cause the following inquiry to appear on the display:
Original values to be loaded ? (+) = Yes, (-) = No
If the function was started inadvertently, the process can be discontinued by operating the “-“ key (No). If the “+“ (Yes) key is pressed, all parameters will be set to the factory-set values.
Attention:
These values preprogrammed at the factory are not yet saved, however. This means that the old values will be effective after powering the CPIK frequency inverter off and on again, unless saving (5.2.3 Save changed parameters to EPROM) was effected before.
As soon as all parameters have assumed their original state, the following display will appear: ! Original values have!
5.2.5 Individual parameters as factory-set
If a parameter is to be set to its factory-set value, the parameter will have to be displayed as described in chapter 5.2.1 Display and change of parameters. If keys “+“ and “-“ are pressed simultaneously after operating the „parameter“ key (for changing its value), the factory-set values will be displayed. No other parameters will be changed.
5.3 Error stack
Error messages are stored in the EPROM. The entries can be visualized on the display. 5.3.1 Display error stack
For this purpose, key “-“ will have to be pressed with parameter 0 during parameter selection (see chapter 5.2.1 Display and change of parameters). The error then displayed is that which occurred last.
Number of error entries Error description or number ↓ ↓
1/34 Control voltage on 283:45:30 24
↑ ↑
Operating hours Additional information
The old stack entries will be displayed by operating the “-“ key repeatedly. New entries can be displayed again by pressing the “+“ key.
5.3.2 Delete error stack
Display of stack contents (see chapter Display error stack) and press “save key”. Acknowledge with “+“ key in response to the display “error stack to be deleted ?“. The entry “error stack deleted“ will then be displayed. 5.3.3 End error stack
Parameter selection will be displayed again after the “parameter“ key has been pressed. 5.4 Parameters
Parameters are divided into:
Variable parameters (see chapter 5.4.1 Variable parameters) which can alter the performance of the device. Display parameters (see chapter 5.4.2 Display parameters) for showing different operating states.
The available parameters depend on the software version used. 5.4.1 Variable parameters
P 0: Reference value start delay (Brake on delay time) tSTS
The delay time between activation of the brake and enabling of the drive can be set in lifts without brake acknowledgement. The reference value will not be started until the brake is disengaged. Values between 50 and 5000 ms can be set. The typical value is between 300 ms and 800 ms.
This value must be set to 5000 ms in lifts with brake acknowledgement. This means that the reference value start depends on the brake acknowledgement.
P 1: Brake application time (brake off delay time) tBE
Setting of the delay time between electrical disengagement of brake by EBS and mechanical “application“ of the brake. After expiry of this period of time, electrical disconnection (controller disable) of the frequency inverter will follow. Values between 50 and 5000 ms can be set.
P 2: Full scale motor rpm (TAC50K mode) This parameter is available for speed limitation.
P 3: Direction of rotation
The motor’s direction of rotation can be changed through this parameter. The parameter can be set to "not inverted" or “inverted“ only.
P 3 Direction of rotation → not inverted
A change of this parameter brings about an immediate change of the direction of rotation.
P 4: Control direction
a) Asynchronous motor : The fact that the polarities of reference speed and actual speed values are in a correct relation to each other is of importance to the speed controller. If this is not the case, the motor will rotate irregularly at low speed. The control direction can be reversed through parameter P 4. The parameter can be set to 'not inverted' or 'inverted' only. A change of this parameter has the same effect as a reversal of two phases of the motor line.
b) Synchronous motor : This parameter is not available for synchronous motor. The motor connections U, V, W of synchronous motors must be connected exactly to prevent wrong assignment to encoder and magnet positions (poles). i.e. the control direction cannot be changed by interchanging two phases. P 5: Speed controller - P gain
This is where the speed controller response can be set. (Setting values 0 ... 50 / default value 8). A change of parameter will become effective immediately.
P 6: Speed controller - I gain
Same as P5, but for the I component (setting values 0 ... 70 / default value 50 ms).
The smallest effective value is 4 ms. If the I component is to be deactivated, 0 ms will have to be entered. P 7: Selection of language
This is where the language can be selected. Language selection is in plain text. P 7 language
→ English
P 8: RS-485 mode
This is where a TIC or TCM or TAC50K interface can be preset (default off). <0> : TCM (if there is no TIC board) or TIC (if there is TIC board) <5> : TAC50K
P 10 ~ P 11: Analog outputs MP42A, 43A on board TMI2

P 13 ... P 17: Ratio
Parameter P 13 to P 16 can be used for computing the ratio between motor speed and car speed. In so doing the maximum motor speed required for reaching the rated speed will be computed.
These parameters have a direct effect on the rated speed computed (P 17) and therefore on the speed of the lift.
P 13: Gear ratio
When a geared drive is used, the ratio of the gear can be set here. The ratio of gearless drives is 1.0. The ratio of gears is often stated as a relation (e.g. 50:2). However, the entry into P13 must be in decimal notation (50:2 => 25.0).
P 14: Traction-sheave diameter
This parameter can be used for setting the traction-sheave diameter in mm. P 15: Suspension
The number of suspensions has a direct effect on the ratio (see gear ratio). The ratio is always indicated as whole number.
P 16: Run speed vmax
The maximum run speed of the lift can be set here. Setting in m/s. P 17: Calculated maximum speed nrated
The required maximum speed of the motor is automatically calculated from the values of parameters P 13 to P 16 and then displayed.
P 18: Operating point for N=0
End of run will be reached, if the speed falls below the speed set here. Relay EBS will drop out (board TIC / X1 , terminals 1a and 2a).
P 19: Acceleration change (jerk) Set desired acceleration change (jerk) [m/s³]. P 20: Acceleration Set desired acceleration / deceleration in [m/s²]. P 21: Acceleration precontrol ON / OFF
Should the drive tend to overshoot or undershoot, the running performance can be improved by activating the acceleration precontrol. This particularly applies to gearless drives.
P 22: Acceleration precontrol value
For assessment of the correct setting of acceleration precontrol, the actual speed value ( P10 to “0”) should be measured at measuring point 42A and the controller output (P 11 to “7”) should be measured at point 43A.

If no recorder is available, these measurements can also be made with a digital voltmeter. Parameter for speed setting
• One of the five speeds is selected via inputs at connector X1 on TIC board TIC. • When more than one speeds are selected at the same time, the order is as follows:
Inspection speed Vi has priority, i.e. as soon as vi is selected, all other speeds will be ignored.
Leveling speed V0 can always be selected and will not be effective until all the other speeds are inactive. • After selecting a speed value, a nominal/actual value comparison will be carried out (“tolerance band
monitoring”). Excessive variance causes emergency stop to be activated.
nominal value exceeds 130% of the respective actual value.
• Acceleration and jerk values are the same for all run characteristic sections (acceleration, deceleration, lower and upper rounding).
• The stopping distance from leveling speed and V0 to “electrically activated stop” (zero speed) is only dependent on value V0 and the set jerk of the run characteristics. This stopping distance cannot be parameterized separately.
Example: V0 = 0.1 m/s, jerk = 0.8 m/s3 -> stopping distance : 35mm. • Short run function only work at rated speed Vn.
• Normal leveling speed V0 is 0.1 m/s ; if value V0 is lower the “leveling time” will increase substantially. P 23: Speed V0 Leveling speed V0 [m/s].

Select “intermediated speed” in parameter P48 or P49 to activate. Otherwise parameters P29 to P32 cannot be displayed. Corresponding +24V input signals X1.11a (for P48) or X1.9b to be present.
When selecting Vi or V0 and another intermediated speed at the same time the following will apply: • inspection speed Vi has priority, i.e. as soon as vi is selected, all other speeds will be ignored.
• Leveling speed V0 can always be selected and will not be effective until all the other speeds and inactive.

P 37 : Operating point v < 0.3
Speed can be set within a range of 0.15 ~ 0.3 m/s. As soon as the speed falls below the set speed, the contact at terminals 11b and 12b on board TIC will be closed. The set operating point is provided with a hysteresis of ±1% of Vn.

Reverse rotation of a car on disengagement of the brake can be reduced by entering a starting torque. This specification is made either with the help of a load-weighing device or it can be entered for a single specific load condition, if no load-weighing device is available.
a) without load-weighing device
If no load-weighing device is available, the load specification can be enabled/disabled with P 50 and a fixed value can be entered with P 54. This specification will then be optimal for one load state only. Observe that the values P51 and P52 must be unequal as internal computation is made by formula [(P 51 - P 52) x P 54].
P 51 = 0, P 52 = 45% (default value) is recommended. P 51: Current value / load weighing
This is where the current loading state of the car is indicated in % of rated load. (Commonly approx. 45 % in the event of load compensation of car). This implies that the load-weighing device was correctly adjusted beforehand.
P 52: Value / load compensation
In the event of load compensation, the loading state must be entered here. It can be determined experimentally as follows:
1. Establish load compensation (car shall not start spinning with the brake disengaged) 2. Read current value from P 51
3. Enter value into P 52
or enter any empirical value, e. g. 45 % means that the counterweight is 45 % of rated load. P 53: Adopt load current
During a run at constant speed with emergency electrical operation (e.g. empty UP or Down) the momentary load current will be displayed. The load specification will be computed internally from this current value by operating the “+“ or “- “ key during this run at constant speed.
The value in P 54 will be overwritten. P 54: Load specification - gain
The value (with sign) of gain calculated here will be specified through P 53. A fine adjustment, if necessary, can be made here.
Improved starting performance for synchronous motors using load controller P 54: Control position controller gain (without load weighing)
Sensor for signaling load weighing is no longer necessary, which improves the staring performance of synchronous gearless drive. Load weighing is electrical through the high resolution load signal from the sine/cosine encoder.
A position controller replaces the existing precontrol signal from the load sensor. As soon as the pulses are enabled and the brake opened, the car is hold in its momentary position through the load controller.
Intervention gain to be set through parameter P 55. The position controller is disabled at the running characteristic start to permit control to be effected by the speed controller.
Preparation
TMI2 board: EPROM version from V5.5b. FLASH program from F030701. P 0 = 280ms re-adjust reference value start delay
P 50 = OFF switch off load weighing
P 55 = 5 (start value) enable control of position controller gain Setting
When starting from upper-most landing downwards with the car empty, P 55 will be set to a value reverse rotation. Small values to be selected, preferably.
Check selected setting during performance in opposite run direction and readjust P 55 to avoid jerk. Values from P 55 = 0.1 to 25 to be selected.
Note
Retrofitting of existing installation is possible. The method above does not replace use of overload sensor. “Occupied”, ”abuse” and “no-load” conditions cannot be recognized. P55: Position controller gain (only with synchronous machine with EnDat encoder)
The precontrol signal supplied through load weigh device is replaced by a position controller computer. After entering pulse enable and release of brake, the car is retained in its momentary position through the position controller. With P55 the position controller gain can be adjusted. Thereby P50 must be switched OFF and P0 must be corrected to 280 ms
