11.1.1 WIRING CHECK
Wiring check is very important and must be carefully made. If checking of some items is
overlooked during wiring check, abnormal operations may frequently occur in a late stage
of trial run adjustment. In this case, it is very time-consuming to locate the causes of the
abnormal operations. Complete wiring check is the basis of carrying out the trial run
adjustment smoothly. In the wiring check, it is necessary to confirm not only the proper I
connections of circuits but also to check wiring route, size and kind of wires, presence and
polarity of surge suppressors, etc.
11.1.2 POWER-ON CHECK
When the wiring check is completed, the power to the system should be turned on. When the
power is turned on, the control power unit (5 VDC and 100VAC, power supply, of CRT
control station are simultaneously turned on) is first turned on and then the servo power
unit approximately two seconds later.
The power to the system should be turned on while carefully monitoring the system.
If the machine runs roughly or uncontrollably at the time of turn-on of servo power,
immediately turn off the power. The machine may run abnormally in the following cases •
and the wiring must be rechecked.
I
• Motor connections are reversed.
• Tachometer-generator connections are reversed.
• A-phase and B-phase of PG connections are reversed.
