Pre-Operation Checks
WARNING!
Wait for 5 minutes after disconnecting power before working on any part of the
system or removing the terminal cover from the Servo Drive.
Initial checks before applying power:
•
Mains power supply voltage is correct.
•
Motor is of correct voltage rating and is connected with the correct polarity.
•
Check all external wiring circuits - power, control, resolver, motor and earth connections.
Note:
Completely disconnect the Servo Drive before point to point checking with a buzzer, or
when checking insulation with a Meggar.
•
Check for damage to equipment.
•
Check for loose ends, clippings, drilling swarf etc. lodged in the Servo Drive and system.
•
If possible check that the motor can be turned freely, and that any cooling fans are intact and
free from obstruction.
Ensure the safety of the complete system before the Servo Drive is energised:
•
Ensure that rotation of the motor in either direction will not cause damage.
•
Ensure that nobody else is working on another part of the system which will be affected by
powering up.
•
Ensure that other equipment will not be adversely affected by powering up.
Prepare to energise the Servo Drive and system as follows:
•
Remove the supply fuses, or isolate using the supply circuit breaker.
•
Disconnect the load from the motor shaft, if possible.
•
Check external run contacts are open.
•
Check external speed setpoints are all zero.
