Why is the Indramat Power Supply display red and showing a stored fault?
This can occur if the braking power of the drive is too high. To resolve this, check the energy content of the drives, reduce drive speed, or increase the load cycle time. Also, evaluate the bleeder pre-warning contact (BVW contact). Alternatively, the bleeder might be defective, or there could be an internal fault in the unit, requiring a replacement.
What to do if Indramat Power Supply display is dark and showing a fault that is not stored?
First, check the main connection, ensuring it matches the rated value of 3 x 380...480 VAC ± 10 %. The issue might be due to the main fuse being activated, a missing mains phase at X7, or a mains voltage that is too low.
How to troubleshoot dark display with not stored fault on Indramat Power Supply?
A dark display with a fault that is not stored may indicate several issues. First, check the circuit at X2/6 (+ 24 VL against 0 VL), because the mains contactor might not be on. Next, verify the connection of the smoothing bus choke (between X7/1L+ and X7/2L+), because the DC bus smoothing choke might be missing or improperly connected. Finally, the rectifier could be faulty, requiring unit replacement.
What causes a flashing display with a stored fault on an Indramat Power Supply?
A flashing display with a stored fault can be caused by a defective drive module, a damaged motor power cable, a short circuit in the motor, or a disconnected DC bus smoothing choke. Remove the conductor rails to the drive module and check the drive module, motor power cable, motor, and DC bus smoothing choke. Replace any components as necessary. Another possible cause is a short-circuit in the unit itself, which would require replacing the unit.
How do I fix a dark Indramat Power Supply display when a fault is not stored?
A dark display with a fault that is not stored could be due to a missing or faulty mains input voltage for the electronic supply. Check the mains fuse in the control panel. Alternatively, the maximum load of the signal voltages might be exceeded. Try disconnecting the wire-ribbon connection (X1) to the drive modules and check voltages at X3. Also, disconnect signal voltages and check for short-circuits (+ 24 V: max. 2 A; ± 15 V: respect. max. 100 mA).
