The thousands location specifies whether the analog input 0 (=0) or analog output 1 (= 1) is involved.
The hundreds location specifies the fault type:
0: No calibration data available.
1: Offset too high (> 100 mV).
The tens and ones location specifies the number of the input involved.
Remedy: Power down the unit and power up again.
If the fault is still present, replace the module/board.
235207 <location>TM: Temperature fault/alarm threshold exceeded
Message %1
value:
Drive object: All objects
Reaction: A_INFEED: OFF2 (NONE, OFF1)
SERVO: OFF2 (NONE, OFF1, OFF3)
VECTOR: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The temperature measured using the temperature sensing of the Terminal Module (TM) (r4105) has
exceeded the threshold value to initiate this fault (p4102[1]) - or the temperature exceeded the alarm
threshold (p4102[0]) for longer than the dead time in parameter p4103.
Please note that this fault can only be initiated if the temperature evaluation was activated (p4100 = 2
for KTY sensor or p4100 = 1 for PTC sensor).
Fault value (r0949, interpret decimal):
The hundred thousands and ten thousands location specifies the component number of the TMxx
where the fault occurred.
Alarm:
Please note that Fault F35207 only causes the drive to be shut down if there is at least one BICO inter-
connection between the drive and TM31.
Remedy: - allow the temperature sensor to cool down.
- if required, set the fault response to NONE (p2100, p2101).
235211 <location>TM: Temperature alarm threshold exceeded
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The temperature measured using the temperature sensing of the Terminal Module (TM) (r4105) has
exceeded the threshold value to initiate this alarm (p4102[0]).
Alarm value (r2124, interpret decimal):
The hundred thousands and ten thousands location specifies the component number of the TMxx
where the fault occurred.
Remedy: Allow the temperature sensor to cool down.
235220 <location>TM: Frequency limit reached for signal output
Message -
value:
Drive object: All objects
Reaction: A_INFEED: OFF1 (NONE, OFF2)
SERVO: OFF1 (NONE, OFF2, OFF3)
VECTOR: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The signals output from the Terminal Module 41 (TM41) for tracks A/B have reached the limit fre-
quency. The output signals are no longer in synchronism with the specified setpoint.
