Faults and alarms
List of faults and alarms
Remedy: - repeat the operation.
- check the DRIVE-CLiQ connection.
Reaction upon F: NONE (IASC/DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
Reaction upon N: NONE
Acknowl. upon N: NONE
F07551 Drive encoder: No commutation angle information
Message value: Fault cause: %1, drive data set: %2
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2 (IASC/DCBRAKE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The commutation angle information is missing. This means that synchronous motors cannot be controlled (closed-
loop control)
Fault value (r0949, decimal interpretation):
yyyyxxxx dec: yyyy = fault cause, xxxx = drive data set
yyyy = 1 dec:
The motor encoder used does not supply an absolute commutation angle.
yyyy = 2 dec:
The selected ratio of the measuring gear does not match the motor pole pair number.
Remedy: Re fault cause = 1:
- 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 (r0313) is an integer multiple of the
encoder pulse number (p0408).
- activate the pole position identification routine (p1982 = 1).
Re fault cause = 2:
- the quotient of the pole pair number divided by the ratio of the measuring gear must be an integer number: (p0314
* p0433) / p0432.
Note:
For operation with track C/D, this quotient must be less than 8.

factor, motor/load revolutions)
F07552 (A) Drive encoder: Encoder configuration not supported
Message value: Fault cause: %1, component number: %2, encoder data set: %3
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2 (IASC/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 interpretation):
ccccbbaa hex: cccc = fault cause, bb = component number, aa = encoder data set
cccc = 1: encoder sin/cos with absolute track (is supported by SME25).
cccc = 3: Squarewave encoder (this is supported by SMC30).
cccc = 4: sin/cos encoder (this is supported by SMC20, SMI20, SME20, SME25).
cccc = 10: DRIVE-CLiQ encoder (is supported by DQI).
cccc = 12: sin/cos encoder with reference mark (this is supported by SME20).
cccc = 15: Commutation with zero mark for separately-excited synchronous motors with VECTORMV.
cccc = 23: Resolver (this is supported by SMC10, SMI10).
cccc = 65535: Other function (compare r0456 and p0404).
See also: p0404 (Encoder configuration effective), r0456 (Encoder configuration supported)
Remedy: - check the encoder parameterization (p0400, p0404).
- use the matching encoder evaluation (r0456).
