A07531

Drive: Command Data Set CDS not present

Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The selected command data set is not available (p0836 > p0170). The command data set was not changed over.
See also: p0810 (Command data set selection CDS bit 0), r0836 (Command Data Set CDS selected)
Remedy: - select the existing command data set.
- set up additional command data sets.
A07541

Drive: Data set changeover not possible

Message value: -
Message class: Application / technological function faulted (17)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: NONE
Acknowledge: NONE
Cause: The selected drive data set changeover and the assigned motor changeover are not possible and are not carried out.
For synchronous motors, the motor contactor may only be switched for actual speeds less than the speed at the start
of field weakening (r0063 < p0348).
See also: r0063 (Speed actual value)
Remedy: Reduce the speed to below the speed at the start of field weakening (r0063 < p0348).
A07550 (F, N)

Drive: Not possible to reset encoder parameters

Message value: %1
Message class: Hardware / software error (1)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
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, interpret decimal):
Component number of the encoder involved.
Remedy: - repeat the operation.
- check the DRIVE-CLiQ connection.
Reaction upon F: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, 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
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: OFF2 (IASC/DCBRK)
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, interpret decimal):
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.
