ROUTINE CHECK

The TPC-Jr is designed in such a way that adjustment is minimized. To use the TPC-Jr under the best conditions for a long time, however, check the following items:

◆ Does the fan rotate properly? (Check everyday.)

The fan is in the controller. When the power is turned on, the fan makes noise. Check the sound.

◆ Is the TPC-Jr controller clean? (Check periodically.)

The TPC-Jr controller is drip-proof but not completely drip-proof.

When oil or cutting liquid splashes on it, wipe it up with a cloth as soon as possible.

Do not lay the controller directly on the floor. Place it on a base that does not vibrate.

It should be placed in a place where dust, machining oil, or cutting liquid does not directly splash on it.

◆ Is an abnormal sound heard when the rotary table rotates? (Check daily.)

When starting the machine for the first time of the day, do test running at low-speeds with the jog mode. Check that no abnormal noise is heard during test running. (Also see the instruction manual for the rotary table.)

※ The TPC-Jr controller has a sealed structure. Therefore, the case may be hot during operation. This is not abnormal.

※ The power plug attached is for checking the functions. Please replace the plug according to the installation condition when installing the TPC-Jr.

Be sure to ground before use.

2ndF C 3. ALARMS

3-1. Alarm Display

When an alarm condition is detected, an alarm number and a brief message are displayed on line 1 on the display screen.

At the same, “RDY” (ready) on line 1 changes to “ALM” (alarm) and the ALM lamp on the control unit blinks.

Alarm display

While an alarm is being displayed, an asterisk (*) blinks.

3-2. Resetting an Alarm

To reset an alarm, press the key.

If “ALM” on line 1 does not disappear, possible causes are as follows:

① In addition to the alarm displayed, there is another alarm condition.

② A servo alarm occurred, which can be reset only by turning off the power supply.

③ An overheat alarm occurred, which cannot be reset until the inside of the control unit cools to a normal temperature.

④ An overtravel alarm occurred, which requires that the rotary table be moved manually.

To display an alarm message for these alarms, press the and keys.

3-3. Alarm Output Signals

In addition to alarm display, an alarm signal is output at detection of an alarm condition.

Either a/b contact can be selected for an alarm output signal by a parameter.
