Encoder 3: Parameteriz. error
Reaction:
NONE (DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge:
IMMEDIATELY
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 (p0189).
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 p0189.
A33920 (F)
Encoder 3: 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, OFF1, OFF2, OFF3, STOP1, STOP2)

A33999 (F, N)
Encoder 3: Unknown alarm
Reaction:
NONE
Acknowledge:
NONE
Cause:
A alarm has occurred on the sensor module for encoder 3 that cannot be interpreted by the control unit firmware.
This can occur if the firmware on the sensor module for encoder 3 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, OFF1, OFF2, OFF3, STOP1, STOP2)
