- Deactivate emergency retraction (MD 1636).
- Switch off feedforward control (MD 1004.0).
- Deactivate MIN-MAX memory (MD 1650.0).
- Reduce the number of DAC output channels (max. 1 channel).
- Deactivate variable signaling function (MD 1620.0).
- Deactivate encoder phase error compensation (MD 1011.1).
- Increase the position control cycle time on the NC.
- Increase the time slice during which the system error occurred or
- Increase lower-level time slices.
- Deselect functions, which are no longer required.
- Use performance instead of standard control module.

Servo sign-of-life monitoring not updated.
-
-
Upon servo enable, the NC must update the sign-of-life monitoring in each position con-
trol cycle. In case of error, sign-of-life monitoring has not been updated for at least two
consecutive position control cycles.
Causes: NC failure, communication failure on the drive bus. Hardware error on drive mod-
ule or hardware error on NC CPU, if error occurs sporadically every few hours.
Check cable connections, perform remedial measures (check shielding or ground con-
nection). Replace the NC hardware, replace the control module. Replace the NC CPU
with the "VB" version, replace the control module.

Error in state switch cabinet
1A : DS <> 1 with CS = 0 (DS = defined/specified state, CS = current/actual state)
2A : DS <> 1, 2, 3, 4, 5
2B : DS-CS <> 0, 1
2C : DS = 3 on PO parameterization error
3A : DS <> 1, 2, 3, 4, 5
3B : DS-CS <> 0, 1
-
The power-up of the drive modules is grouped into 5 states (steps). The states are speci-
fied consecutively by the NC and acknowledged by the drive. An error occurs when an
invalid desired state is detected in the drive.
Cause: Communication failure on the drive bus. Hardware error on the drive module,
hardware error on the NC.
Check cable connections, perform remedial measures (check shielding or ground con-
nection). Replace the control module, replace the NC hardware.
