ATV61 What can be done to troubleshoot a blank HMI?

Product Line:
All

Environment:
All

Cause:
None

Resolution:
Basic troubleshooting:
Verify the drive has line voltage (L1- L2-L3) . Measure on the drive terminals.
Verify the drive has DC Bus voltage. Measure between PA/+ and PC/-.
Verify the control power supplies +24Vdc to com and +10Vdc to com.
Verify that there is no Ethernet IP or Modbus TCP/IP connection to the integrated Modbus/Canopen port on the drive.   If Ethernet is connected to the Modbus/Canopen port, the +10V power supply can be pulled down causing the display to go blank and the drive to become unresponsive to commands.
