Pre-Operation Checks
Before Applying Power:
♦
Read the Safety section at the front of the Manual.
♦
Ensure that all local electric codes are met.
♦
Check for damage to equipment.
♦
Check for loose ends, clippings, drilling swarf etc. lodged in the drive and system.
♦
Check all external wiring circuits of the system - power, control, motor and earth connections.
♦
If your application requires the Safe Torque Off function, read chapter 6. Otherwise disable it; example
wiring diagrams, including how to disable Safe Torque Off, are shown in that chapter.
♦
Ensure that unexpected rotation of the motor in either direction will not result in damage, bodily harm or
injury. Disconnect the load from the motor shaft, if possible.
♦
Check the state of the Motor Thermistor and Brake Resistor connectors. Check external run contacts are
open. Check external speed setpoints are all at zero.
♦
Ensure that nobody 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.
♦
Check motor stator connections are correctly wired for Star or Delta as necessary for drive output
voltage.
