A31431 (F, N)
Encoder 1: Deviation position incremental/absolute too large
Message value:
%1
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction:
NONE
Acknowledge:
NONE
Cause:
When the zero pulse is passed, a deviation in the incremental position was detected.
For equidistant zero marks, the following applies:
- The first zero mark passed supplies the reference point for all subsequent checks. The other zero marks must have
n times the distance referred to the first zero mark.
For distance-coded zero marks, the following applies:
- the first zero mark pair supplies the reference point for all subsequent checks. The other zero mark pairs must have
the expected distance to the first zero mark pair.
Alarm value (r2124, interpret decimal):
Deviation in quadrants (1 pulse = 4 quadrants).
See also: p0491 (Motor encoder fault response ENCODER)
Remedy:
- check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
- replace the encoder or encoder cable.
- Clean coding disk or remove strong magnetic fields.
Reaction upon F:
NONE (ENCODER, IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Acknowl. upon F:
IMMEDIATELY
Reaction upon N:
NONE
Acknowl. upon N:
NONE
A31432 (F, N)
Encoder 1: Rotor position adaptation corrects deviation
Message value:
%1
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction:
NONE
Acknowledge:
NONE
Cause:
For 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).
Reaction upon F:
NONE (ENCODER, IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Acknowl. upon F:
IMMEDIATELY
Reaction upon N:
NONE
Acknowl. upon N:
NONE
A31442 (F, N)
Encoder 1: Battery voltage pre-alarm
Message value:
-
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
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.
