Overview of Alarms
SINAMICS-Alarms
Remedy: CI: Set p4420 = 0 and re-wire.
235228 <location>TM: Sampling time p4099[3] invalid
Message -
value:
Drive object: TM41
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The value of the cycle time for the incremental encoder emulation, specified in p4099[3] does not cor-
respond to a valid value. The system has already changed p4099[3] to a valid value. The parameters
of the TM41 in question must be saved on the memory card and a POWER ON carried out.
If necessary, the sampling time can be checked again the next time the system is switched on, taking
into account any other TM41s located on the same DRIVE-CLiQ line.
The following rules must be observed when setting p4099[3]:
- if several TM41 are located on a DRIVE-CLiQ line, the same sampling time in p4099[3] must be set
for all components.
- the sampling time of a TM41 in SINAMICS mode (p4400) must correspond to that of the emulated
encoder. The encoder sampling time is normally the same as the parameter value p0115[0] of the
drive object used to interconnect the TM41 via connector input p4420.
- it is not possible to operate two TM41s on one line if they emulate encoders with different cycles.
Remedy: None necessary.
235229 <location>TM time slice de-activated
Message %1
value:
Drive object: TM41
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The required value of a cycle time in p4099[0...2] is invalid.
The corresponding time slice was not activated.
Alarm value (r2124, interpret decimal):
0: Digital input/outputs (p4099[0])
1: Analog inputs (p4099[1])
3: Encoder emulation (p4099[3]).
4: Encoder emulation speed setpoint (p4099[3]).
5: Encoder emulation speed setpoint (p4099[3]).
6 Internal sequence control of the TM41 (internal error)
Remedy: The sampling time p4099[0] may not be zero. Change the sampling time corresponding to the error
code.
235230 <location>HW problem with the TM module
Message %1
value:
Drive object: A_INF, B_INF, S_INF, SERVO, TM15DI_DO, TM31, TM41, VECTOR
Reaction: A_INFEED: OFF1 (NONE, OFF2)
SERVO: NONE
VECTOR: NONE
Acknowledge: POWER ON
Cause: The terminal module used has signaled an internal error. Signals of this module may not be evaluated
and are potentially incorrect.
Remedy: The module must be replaced if no other alarms that refer to a communications error are present in
the system.
235231 <location>TM: Master control by PLC missing
Message -
value:
Drive object: TM41
Reaction: NONE
Acknowledge: NONE
