Cause: The signals output from the terminal module 41 (TM41) for tracks A/B have reached the
limit frequency. The output signals are no longer in synchronism with the specified setpoint.
Remedy: - enter a lower speed setpoint (p1155).
- reduce the encoder pulse number (p0408).
235221 <location>TM: Setpoint - actual value deviation, outside the tolerance
range
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The deviation between the setpoint and the output signals (track A/B) exceeds the
tolerance of +/-3 %.
Remedy: - reduce the basic clock cycle (p0110, p0111).
- replace the module.
235222 <location>TM: Encoder pulse number not permissible
Reaction: NONE
Acknowledge: NONE
Cause: The encoder pulse number entered does not match the permissible pulse number from a
hardware perspective.
Fault value (r0949, decimal):
1: Encoder pulse number is too high.
2: Encoder pulse number is too low.
4: Encoder pulse number is less than the zero mark offset (p4426)
Remedy: Enter the encoder pulse number in the permissible range (p0408).
235223 <location>TM: ZM offset not permissible
Reaction: NONE
Acknowledge: NONE
Cause: The entered zero mark offset is not permissible.
Fault value (r0949, decimal):
1: Zero mark offset is too high.
Remedy: Enter the zero mark offset in the permissible range (p4426).
235801 <location>TM DRIVE-CLiQ: Sign-of-life missing
Reaction: NONE
Acknowledge: NONE
Cause: A DRIVE-CLiQ communications error has occurred between the control unit and the
terminal module involved.
Alarm value (r2124, hexadecimal):
0A: The sign-of-life bit in the receive telegram is not set.
Remedy: - check the DRIVE-CLiQ connection.
- replace the component involved.

235802 <location>TM: Time slice overflow
Reaction: NONE
Acknowledge: NONE
Cause: Time slice overflow on terminal module.
Remedy: Replace the terminal module.
235803 <location>TM: Memory test
Reaction: NONE
Acknowledge: NONE
Cause: An error has occurred in the RAM test on the terminal module.
