4.2 List of faults and alarms
A35214 (F, N) TM: Temperature alarm threshold channel 3 exceeded
Drive object: DCP_CTRL, TM150
Cause: The temperature measured using the temperature sensing of the Terminal Module (TM) (r4105[3]) has exceeded the
threshold value to initiate this alarm (p4102[6]).
Note:
For sensor type "PTC thermistor" and "Bimetallic NC contact" (p4100[3] = 1, 4), the following applies:
- if r4101[3] > 1650 ohms, the temperature r4105[3] = 250 °C
- if r4101[3] <= 1650 ohms, the temperature r4105[3] = -50 °C
Alarm value (r2124, interpret decimal):
Temperature actual value at the time of initiation [0.1 °C].
Remedy: - allow the temperature sensor to cool down to below p4102[6] - hysteresis (5 K); for TM150, can be set using
p4118[3].

F35220 (N, A) TM: Frequency limit reached for signal output
Drive object: DCP_CTRL, TM15DI_DO, TM31
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.
SIMOTION (p4400 = 0) operating mode:
- If the TM41 has been configured as the technology project, this fault is also output in response to short-circuited A/B
signals in X520.
SINAMICS (p4400 = 1) operating mode:
- the fine resolution of TM41 in p0418 does not match that of the connector input that was interconnected at p4420
- the encoder position actual value r0479 interconnected at connector input p4420 has an excessively high actual
speed
- the output signals correspond to a speed, which is greater than the maximum speed (r1082 of TM41).
Remedy: SIMOTION (p4400 = 0) operating mode:
- enter a lower speed setpoint (p1155).
- reduce the encoder pulse number (p0408).
- check track A/B for short-circuits.
SINAMICS (p4400 = 1) operating mode:
- enter a lower speed setpoint (p1155).
- reduce the encoder pulse number (p0408).
Notice:
The output signal is no longer monitored after changing the message type to "Alarm" (A).
F35221 (N, A) TM: Setpoint - actual value deviation outside the tolerance range
Drive object: DCP_CTRL, TM15DI_DO, TM31
Cause: The deviation between the setpoint and the output signals (track A/B) exceeds the tolerance of +/-3 %. The deviation
between the internal and external measured value is too high (> 1000 pulses).
Remedy: - reduce the basic clock cycle (p0110, p0111).
- if required, replace the component (e.g. internal short-circuit).
A35222 (F, N) TM: Encoder pulse number not permissible
Drive object: DCP_CTRL, TM15DI_DO, TM31
Cause: The encoder pulse number entered does not match the permissible pulse number from a hardware perspective.
Fault value (r0949, interpret 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).
- if necessary, replace TM41 SAC with TM41 DAC.
Note:
TM41 SAC: order no. = 6SL3055-0AA00-3PA0
TM41 DAC: order no. = 6SL3055-0AA00-3PA1
