Issue:
Altivar Process Drive display screen is blank.
Product Line:
Altivar Drive AC Drive ATV630 ATV930
Environment:
All
Cause:
Electrical Continuity
Resolution:
If remotely mounted, try connecting to the face of the drive.
Check +10v dc and +24v dc terminals to COM.
If using Communications for Monitoring or Control, ensure that no one connected the Ethernet Cable to a Modbus/HMI Port.
If not an Ethernet issue, and the +10v, +24v are not present, check PA to PC on the bottom of the drive near line and load terminals. You should read the {Line Voltage x 1.414} around 650v dc if 460v system, or 340v dc if 230v system.
If you have no measurable voltage on PA to PC, check your Line Terminals to ground on the Drive.
If line voltage (measured on the L1,L2,L3 terminals of the drive is correct, but DC bus voltage is low/zero, then there is likely an internal issue in the in the drive. Perform a static check on the inputs to confirm.
