A31811 (F, N) Encoder 1: Encoder serial number changed
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The serial number of the motor encoder of a synchronous motor has changed. The change was only checked for
encoders with serial number (e.g. EnDat encoders) and build-in motors (e.g. p0300 = 401) or third-party motors
(p0300 = 2).
Cause 1:
- The encoder was replaced.
Cause 2:
- A third-party, built-in or linear motor was re-commissioned.
Cause 3:
- The motor with integrated and adjusted encoder was replaced.
Cause 4:
- The firmware was updated to a version that checks the encoder serial number.
Note:
With closed-loop position control, the serial number is accepted when starting the adjustment (p2507 = 2).
When the encoder is adjusted (p2507 = 3), the serial number is checked for changes and if required, the adjustment
is reset (p2507 = 1).
Proceed as follows to hide serial number monitoring:
- set the following serial numbers for the corresponding Encoder Data Set: p0441= FF, p0442 = 0, p0442 = 0, p0444
= 0, p0445 = 0.
- parameterize F07414 as message type N (p2100, p2101).

Remedy: Re causes 1, 2:
Carry out an automatic adjustment using the pole position identification routine. Acknowledge the fault. Initiate the
pole position identification routine with p1990 = 1. Then check that the pole position identification routine is correctly
executed.
SERVO:
If a pole position identification technique is selected in p1980, and if p0301 does not contain a motor type with an
encoder adjusted in the factory, then p1990 is automatically activated.
or
Set the adjustment via p0431. In this case, the new serial number is automatically accepted.
or
Mechanically adjust the encoder. Accept the new serial number with p0440 = 1.
Re causes 3, 4:
Accept the new serial number with p0440 = 1.
Reaction upon F: NONE (ENCODER, OFF2)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
F31812 (N, A) Encoder 1: Requested cycle or RX-/TX timing not supported
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A cycle requested from the Control Unit or RX/TX timing is not supported.
Fault value (r0949, decimal interpretation):
0: Application cycle is not supported.
1: DRIVE-CLiQ cycle is not supported.
2: Distance between RX and TX instants in time too low.
3: TX instant in time too early.
Remedy: POWER ON all components (switch the power off and then back on again).
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
