F31111 (N, A) Encoder 1: Absolute encoder EnDat, internal fault/error
Drive object: All objects
Reaction: A_INFEED: NONE
SERVO: ENCODER (IASC / DCBRAKE, NONE)
VECTOR: ENCODER (IASC / DCBRAKE, NONE)
Acknowledge: PULSE INHIBIT
Cause: The EnDat encoder fault word supplies fault bits that have been set.
Fault value (r0949, interpret binary):
Bit 0: Lighting system failed.
Bit 1: Signal amplitude too low.
Bit 2: Position value incorrect.
Bit 3: Encoder power supply overvoltage condition.
Bit 4: Encoder power supply undervoltage condition.
Bit 5: Encoder power supply overcurrent condition.
Bit 6: The battery must be changed.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy: Re fault value, bit 0 = 1:
Encoder is defective. Replace the encoder, where the motor encoder has a direct DRIVE-CLiQ socket: Replace the
motor.
Re fault value, bit 1 = 1:
Encoder is defective. Replace the encoder, where the motor encoder has a direct DRIVE-CLiQ socket: Replace the
motor.
Re fault value, bit 2 = 1:
Encoder is defective. Replace the encoder, where the motor encoder has a direct DRIVE-CLiQ socket: Replace the
motor.
Re fault value, bit 3 = 1:
5 V power supply voltage fault.
When using an SMC: Check the plug-in cable between the encoder and SMC or replace the SMC.
When a motor encoder with a direct DRIVE-CLiQ connection is used: Replace the motor.
Re fault value, bit 4 = 1:
5 V power supply voltage fault.
When using an SMC: Check the plug-in cable between the encoder and SMC or replace the SMC.
When using a motor with DRIVE-CLiQ: Replace the motor.
Re fault value, bit 5 = 1:
Encoder is defective. Replace the encoder, where the motor encoder has a direct DRIVE-CLiQ socket: Replace the
motor.
Re fault value, bit 6 = 1:
The battery must be changed (only for encoders with battery back-up).

F31112 (N, A) Encoder 1: The error bit is set in the serial protocol
Drive object: All objects
Reaction: A_INFEED: NONE
SERVO: ENCODER (IASC / DCBRAKE, NONE)
VECTOR: ENCODER (IASC / DCBRAKE, NONE)
Acknowledge: PULSE INHIBIT
Cause: Serial communication protocol transfer error between the encoder and evaluation module SMCxx.
