Overview of Alarms
Cause: A fault occurred on the voltage sensing module (VSM) an alarm has occurred that cannot
be interpreted by the control unit firmware.
This can occur if the firmware on the module is more recent than the firmware on the
control unit.
Alarm value (r2124, decimal):
Alarm number.
If required, the significance of this new alarm can be read about in a more recent
description of the control unit.
Remedy: - replace the firmware on the voltage sensing module by an older firmware version (r0xyz).
- upgrade the firmware on the control unit (r0018).
235200 <location>TM: Calibration data
Reaction: NONE
Acknowledge: NONE
Cause: An error was detected in the calibration data of the terminal module.
Alarm value (r2124, decimal):
The hundred thousands and ten thousands location specifies the component Id of the
terminal module where the fault occurred.
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 threshold exceeded
Reaction: 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]).
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, 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 interconnection 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
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, 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
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
