Description of Real Time Clock
NB!
Please note the following parameters are only displayed if the real time clock option is fitted! The real time clock can show the current time and date and weekday. The available digits stipulate how comprehen-sive the readout can be.
Further more the RTC is used to execute events based on time. A total of 20 events can be programmed.
Firstly the current time and date must be programmed in parameter 780 and 781, please see description of parameters. It is important that both parameters are set. Then parameter 782 through 786 and 789 are used to program the events. First set the week-day(s) in parameter 782 when the action shall take place.
Then set the specific time in parameter 783 for the ac-tion, then the action itself in parameter 784. In param-eter 785 set the time for the termination of the action and in parameter 786 the off-action. Please note the on action and off action must be related. E.g. it is not possible to change setup via the on-action in param-eter 784 and then stop drive in paramparam-eter 786. The following selection refers to the choices in parameter 784 and 786. Hence selection [1] to [4] are related, [5]
to [8] are related, [9] to [12] are related, [13] to [16] are related and finally [17] and [18] are related.
* NO ACTION DEFINED [0]
SETUP 1 [1]
It can be chosen if an action, on start-up, shall be exe-cuted even if the ON time has been passed some time ago. Alternatively choose to wait for the next forth coming ON action time before executing the next com-ing action. This is programmed in parameter 789. It is,
however, possible to have several RTC actions within the same period. E.g. relay 1 ON is executed in the first event at 10:00 and relay 2 ON is executed in the sec-ond event at 10:02, before the first event is terminated.
Parameter 655 will show the fault log with the RTC, this parameter is directly related to parameter 616.
Only here the log is based on the real time clock, not running hours from zero. This means a date and time is shown.
780 Set clock (SET CLOCK) Value:
000000.0000 - 991231.2359 000000.0000 Function:
The time and date is set and displayed in this param-eter.
Description of choice:
Enter the current date and time to start the clock as follows: YYMMDD.HHMM
Remember to also set parameter 781.
781 Set weekday
The week day is set and displayed in this parameter.
Description of choice:
Enter the week day to start the clock in conjunction with parameter 780.
WEDNESDAY [3]
MONDAY TO FRIDAY [9]
SAT. AND SUNDAY [10]
MONDAY TO THURS. [11]
FRIDAY TO SUNDAY [12]
SUNDAY TO FRIDAY [13]
Function:
Set the weekday for specific actions to be executed.
Description of choice:
The selection of weekday is used to determine the weekday an action must be executed.
783 ON clock (ON CLOCK) Value:
[Index 00 - 20] 00.00 - 23.59 00.00 Function:
The ON Clock entry defines at which time of the day the corresponding ON Action will take place.
Description of choice:
Enter the time at which the ON action should take place.
784 ON action (ON ACTION) Value:
NO ACTION DEFINED [0]
SETUP 1 [1]
An action to be executed is selected here.
Description of choice:
When the time in parameter 782 is passed the action in the corresponding index is executed. Setup 1 to 4 [1] – [4] is simply selecting setups. The RTC overrules setup selection via digital inputs and bus input. Preset ref [5] – [8] is selecting preset reference. The RTC overrules preset ref selection via digital inputs and bus input. AO42 and AO45 and Relay 1 and 2 [9] – [16]
simply activate or deactivate the outputs. Start drive [17] starts the frequency converter, the command is AND’ed or OR’ed with the digital input commands and the bus command. This, however, depends on the se-lection in parameter 505. Stop drive [18] just stops the frequency converter again.
The OFF Clock entry defines at which time of the day the corresponding OFF Action will take place.
Description of choice:
Enter the time at which the OFF action should take place.
786 OFF action (OFF ACTION) Value:
NO ACTION DEFINED [0]
SETUP 1 [1]
SETUP 2 [2]
PRESET REF. 1 [5]
PRESET REF. 2 [6]
PRESET REF. 3 [7]
PRESET REF. 4 [8]
AO42 OFF [9]
AO42 ON [10]
AO45 OFF [11]
AO45 ON [12]
RELAY 1 ON [13]
RELAY 1 OFF [14]
RELAY 2 ON [15]
RELAY 2 OFF [16]
START DRIVE [17]
STOP DRIVE [18]
Function:
An action to be executed is selected here.
Description of choice:
When the time in parameter 784 is passed the action in the corresponding index is executed. To make the function safe it is only possible to execute a command related to parameter 783.
789 RTC startup (RTC startup) Value:
Execute on actions (EXEC. ON ACTIONS) [0]
Wait new on action (WAIT NEW ON ACTION) [1]
Function:
Decide how the frequency converter shall respond to actions after start-up.
Description of choice:
It can be chosen if an action, on startup, shall be exe-cuted even if the ON time was passed some time ago [0]. Alternatively choose to wait for the next forth com-ing ON action before executcom-ing [1]. When the RTC is enabled, it must be defined how this should be done.
Programming
Status messages
Status messages appear in the 4th line of the display - see example below.
The left part of the status line indicates the active type of control of the frequency converter.
The centre part of the status line indicates the active reference.
The last part of the status line gives the present status, e.g. "Running", "Stop" or "Stand by".
