What Steps Have I Already Taken?
Before You Begin
If you haven't yet done so:
-
Open the electrical cabinet door.
WARNING! Electrocution Hazard: When servicing the machine from inside the electrical cabinet, always use caution. Points in the electrical cabinet have high voltages that can electrocute or shock you. Even after you've powered off the machine, electronic devices in the electrical cabinet may retain dangerous electrical voltages. Only qualified electrical machinery technicians should perform maintenance or troubleshooting procedures inside the electrical cabinet while power is still on.
-
Locate the axes drives.
Troubleshooting Steps
-
Examine the power LEDs on the axes drives. A green light indicates that the axes drives have power through contactor C1.
Are the power LEDs green?
- Yes: Go to Measure the Voltage on Wires 100 and 104.
- No: Go to Press and Hold the Start Button.
