Cause:
A parameter of encoder 1 was detected as being incorrect.
It is possible that the parameterized encoder type does not match the connected encoder.
The parameter involved can be determined as follows:
- determine the parameter number using the fault value (r0949).
- determine the parameter index (p0187).
Fault value (r0949, decimal):
Parameter number.
Remedy:
- check whether the connected encoder type matches the encoder that has been parameterized.
- correct the parameter specified by the fault value (r0949) and p0187.
A31920 (F)
Encoder 1: Temperature sensor fault
Reaction:
NONE
Acknowledge:
NONE
Cause:
When evaluating the temperature sensor, an error occurred.
Alarm value (r2124, decimal):
1: Wire breakage or sensor not connected (KTY: R > 1630 Ohm).
2: Measured resistance too low (PTC: R < 30 Ohm, KTY: R < 340 Ohm).
Remedy:
- check that the encoder cable is the correct type and is correctly connected.
- check the temperature sensor selection in p0600 to p0603.
- replace the sensor module (hardware defect or incorrect calibration data).
Reaction upon F:
NONE (DCBRAKE, ENCODER, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge
IMMEDIATELY
upon F:
A31999 (F, N)
Encoder 1: Unknown alarm
Reaction:
NONE
Acknowledge:
NONE
Cause:
A alarm has occurred on the sensor module for encoder 1 that cannot be interpreted by the control unit firmware.
This can occur if the firmware on the sensor module for encoder 1 is more recent than the firmware on the control
unit.
Alarm value (r2124, decimal):
Alarm number.
If required, the significance of this new alarm can be referred to in a more recent description of the control unit.
Remedy:
- replace the firmware on the sensor module by an older firmware version (r0148).
- upgrade the firmware on the control unit (r0018).
Reaction upon F:
NONE (DCBRAKE, ENCODER, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge
IMMEDIATELY (power on)
upon F:
Reaction upon N:
NONE
Acknowledge
NONE
upon N:
F32100
Encoder 2: Zero mark clearance error
Reaction:
NONE (DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge:
IMMEDIATELY
Cause:
The measured zero mark clearance does not correspond to the parameterized zero mark clearance (p0425 for rotat-
ing encoders).
Fault value (r0949, decimal):
Last measured zero mark clearance in increments (4 increments = 1 encoder pulse).
Remedy:
- check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
. check the encoder type (encoder with equidistant zero marks).
- adapt the parameter for the clearance between zero marks (p0425).
- replace the encoder or encoder cable.
F32101
Encoder 2: Zero mark failed
Reaction:
NONE (DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge:
IMMEDIATELY
