SINAMICS S110 List Manual (LH7), 06/2012, 6SL3097-4AP10-0BP3
A31462 (N) Encoder 1: Analog sensor, no channel active
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: Channel A and B are not activated for the analog sensor.
Remedy: - activate channel A and/or channel B (p4670).
- check the encoder configuration (p0404.17).
See also: p4670 (Analog sensor configuration)
Reaction upon N: NONE
Acknowl. upon N: NONE
A31463 (N) Encoder 1: Analog sensor position value exceeds limit value
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The position value has exceeded the permissible range of -0.5 ... +0.5.
Alarm value (r2124, interpret decimal):
1: Position value from the LVDT sensor.
2: Position value from the encoder characteristic.
Remedy: Re alarm value = 1:
- Check the LVDT ratio (p4678).
- check the reference signal connection at track B.
Re alarm value = 2:
- check the coefficients of the characteristic (p4663 ... p4666).
Reaction upon N: NONE
Acknowl. upon N: NONE
A31470 (F, N) Encoder 1: Soiling detected
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: In the case of the alternative encoder system interface on the Sensor Module Cabinet 30 (SMC30), encoder soiling
is signaled via a 0 signal at terminal X521.7.
Remedy: - check the plug connections
- replace the encoder or encoder cable
Reaction upon F: NONE (ENCODER, IASC/DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
F31500 (N, A) Encoder 1: Position tracking traversing range exceeded
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: For a configured linear axis without modulo correction, the drive/encoder has exceeded the maximum possible tra-
versing range. The value should be read in p0412 and interpreted as the number of motor revolutions.
For p0411.0 = 1, the maximum traversing range for the configured linear axis is defined to be 64x (+/- 32x) of p0421.
For p0411.3 = 1, the maximum traversing range for the configured linear axis is pre-set (default value) to the highest
possible value and is +/-p0412/2 (rounded off to complete revolutions). The highest possible value depends on the
pulse number (p0408) and the fine resolution (p0419).
