Faults and Alarms
List of faults and alarms
F07551
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 can-
not be controlled (closed-loop control)
Fault value (r0949, decimal):
The fault value includes the drive data set number involved.
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 rotor position identification routine (p1982 = 1).
F07552 (A)
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).
Reaction upon A:
NONE
Acknowledge
NONE
upon A:
F07553 (A)
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. In p0430, bits may only be requested that are signaled
by the sensor module in r0458 as being supported.
Fault value (r0949, decimal):
Encoder data set number.
Remedy:
- check the encoder parameterization (p0430).
- use the matching encoder evaluation (r0458).
Reaction upon A:
NONE
Acknowledge
NONE
upon A:
F07560
Drive encoder: Number of pulses is not to the power of two
Reaction:
OFF2 (DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge:
IMMEDIATELY (power on)
Cause:
For rotary absolute value encoders, the pulse number in p0408 must be to the power of two.
Fault value (r0949, decimal):
The fault value includes the encoder data set number involved.
Remedy:
Check parameterization (p0408, p0404 Bit 0 and Bit 1).
Upgrade the sensor module firmware.
F07561
Drive encoder: Number of multiturn pulses is not to the power of two
Reaction:
OFF2 (DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge:
IMMEDIATELY (power on)
Cause:
The multi-turn resolution in p0421 must be to the power of two.
Fault value (r0949, decimal):
The fault value includes the encoder data set number involved.
Remedy:
Check parameterization (p0421, p0404 Bit 0 and Bit 1).
Upgrade the sensor module firmware.
