Signal voltage faulty.
Cause 1: Missing or faulty mains input voltage for electronic supply.
Check mains fuse in the control panel.
Cause 2: Maximum load of the signal voltages exceeded.
1. Disconnect wire-ribbon connection (X1) to the drive modules
and check voltages at X3.
2. Disconnect signal voltages and check for short-circuits
(+ 24 V: max. 2 A;
±
15 V: respect. max. 100 mA).
