Fault display Type Enable Potential causes and corrective actions
Hall e󹪜ect pwr supply F Fixed Cause
All of the supplies that power the Hall E󹪜ects on the drive output have
failed.
Actions
1. Depending on the type used on the drive, verify that the power supply
to the DCR for the Hall E󹪜ect sensors are no greater that -10 % of the
speci󹪝ed output (+/-15 VDC or +/-24 VDC depending on the version
chosen).
2. Check the physical condition and connections of the power supply
wiring harness.
3. Check connection of DB50 cable at the DCR (J3) and the SIB (P1)
4. Check the condition of the DB50 cable between the DCR and the sys‐
tem interface board, ensure continuity of conductors for pins 41 to 50
from one connector through to the other side.
5. If the above steps do not resolve the issue, contact Siemens customer
service.

Note: This feature will be re‐
leased in a later software ver‐
sion.
F Fixed Cause
The DCR power supply has indicated a loss of power. This can either be due
to loss of AC or a failed power supply.
Action
1. Verify that the power supply to the DCR is operating correctly.
– 90 to 264 VAC, 47 to 63 Hz input
– 24 VDC no greater than -10 % of speci󹪝ed output
2. Check the physical condition and connections of the power supply
wiring harness.
3. If the above steps do not resolve the issue, contact Siemens customer
service.
