Cause:
On track A/B, pulses have been lost or too many have been counted. These pulses are presently being corrected.
Alarm value (r2124, interpret decimal):
Last measured deviation of zero mark in increments (4 increments = 1 encoder pulse).
The sign designates the direction of motion when detecting the zero mark distance.
Remedy:
- check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
- replace the encoder or encoder cable.
- check encoder limit frequency.
- adapt the parameter for the distance between zero marks (p0424, p0425).

A32442 (F, N) Encoder 2: Battery voltage alarm threshold reached
Message value:
-
Drive object:
All objects
Reaction:
NONE
Acknowledge:
NONE
Cause:
When switched-off, the encoder uses a battery to back up the multiturn information. The multiturn information can no longer
be buffered if the battery voltage drops even further.
Remedy:
Replace battery.
Reaction upon F: Servo: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)

A32443 (F, N) Encoder 2: Signal level track C/D outside tolerance (alarm)
Message value:
Fault cause: %1 bin
Drive object:
All objects
Reaction:
NONE
Acknowledge:
NONE
Cause:
The unipolar level (CP/CN or DP/DN) for encoder 2 is outside the permissible tolerance.
Alarm value (r2124, interpret binary):
Bit 0 = 1: Either CP or CN outside the tolerance.
Bit 16 = 1: Either DP or DN outside the tolerance.
The unipolar nominal signal level of the encoder must lie in the range 2500 mV +/- 500 mV.
The response thresholds are < 1700 mV and > 3300 mV.
Note:
The signal level is not evaluated unless the following conditions are satisfied:
- Sensor Module properties available (r0459.31 = 1).
- monitoring active (p0437.31 = 1).
Remedy:
- check that the encoder cables and shielding are routed in compliance with EMC.
- check the plug connections and contacts of the encoder cable.
- are the C/D tracks connected correctly (have the signal cables CP and CN or DP and DN been interchanged)?
- replace the encoder cable.
Reaction upon F: Servo: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
