Overview of Alarms
207550 <location>Drive: Not possible to reset encoder parameters
Reaction: NONE
Acknowledge: NONE
Cause: When carrying-out a factory setting (e.g. using p0970 = 1), it was not possible to reset the
encoder parameters. The encoder parameters are directly read out of the encoder via
DRIVE-CLiQ.
Alarm value (r2124, decimal):
Component number of the encoder involved.
Remedy: - repeat the operation.
- check the DRIVE-CLiQ connection.
207551 <location>Drive encoder: No commutation angle information
Reaction: OFF2 (DCBRAKE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The motor encoder used does not supply an absolute commutation angle. This means that
synchronous motors cannot be controlled (closed-loop control)
Fault value (r0949, decimal):
Drive data set number
Remedy: - check the encoder parameterization (p0404).
- use an encoder with track C/D, EnDat interface of Hall sensors.
- use an encoder with sinusoidal A/B track for which the motor pole pair number (p0313) is
an integer multiple of the encoder pulse number (p0408).
- activate the pole position identification routine (p1982 = 1).
207552 <location>Drive encoder: Encoder configuration not supported
Reaction: OFF2 (DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The requested encoder configuration is not supported. Only bits may be requested in
p0404 that are signaled as being supported by the encoder evaluation in r0456.
Fault value (r0949, decimal):
Encoder data set number.
See also: p0404, r0456
Remedy: - check the encoder parameterization (p0400, p0404).
- use the matching encoder evaluation (r0456).
207553 <location>Drive encoder: Sensor module configuration not supported
Reaction: OFF2 (DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The requested sensor module configuration is not supported.
Possible causes:
- bits are set in p0430 (requested functions) that are not set in r0458 (supported functions).
This does not apply for bit 19 (safety position actual value sensing), bit 29 (phase
correction), bit 30 (amplitude correction) and bit 31 (offset correction).
- p1982 > 0 (pole position identification requested), but r0458 bit 16 = 0 (pole position
identification not supported).
Fault value (r0949, decimal):
Encoder data set number.
Remedy: - check the encoder parameterization (p0430).
- check the pole position identification routine (p1982).
- use the matching encoder evaluation (r0458).
207560 <location>Drive encoder: Number of pulses is not to the power of two
Reaction: OFF2 (DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
