Cause: For rotary absolute value encoders, the pulse number in p0408 must be to the power of
two.
Fault value (r0949, decimal):
The fault value includes the encoder data set number involved.
Remedy: Check parameterization (p0408, p0404 Bit 0 and Bit 1).
Upgrade the sensor module firmware.
207561 <location>Drive encoder: Number of multiturn pulses is not to the power
of two
Reaction: OFF2 (DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The multi-turn resolution in p0421 must be to the power of two.
Fault value (r0949, decimal):
The fault value includes the encoder data set number involved.
Remedy: Check parameterization (p0421, p0404 Bit 0 and Bit 1).
Upgrade the sensor module firmware.
207565 <location>Drive: Encoder fault/error in PROFIdrive encoder interface 1
Reaction: NONE
Acknowledge: NONE
Cause: An encoder error was signaled for encoder 1 via the PROFIdrive encoder interface
(G1_ZSW.15).
Alarm value (r2124, decimal):
Error code from G1_XIST2, refer to the description regarding r0483.
Remedy: Acknowledge the encoder error using the encoder control word (G1_STW.15 = 1).
207566 <location>Drive: Encoder fault/error in PROFIdrive encoder interface 2
Reaction: NONE
Acknowledge: NONE
Cause: An encoder error was signaled for encoder 2 via the PROFIdrive encoder interface
(G2_ZSW.15).
Alarm value (r2124, decimal):
Error code from G2_XIST2, refer to the description regarding r0483.
Remedy: Acknowledge the encoder error using the encoder control word (G2_STW.15 = 1).
207567 <location>Drive: Encoder fault/error in PROFIdrive encoder interface 3
Reaction: NONE
Acknowledge: NONE
Cause: An encoder error was signaled for encoder 3 via the PROFIdrive encoder interface
(G3_ZSW.15).
Alarm value (r2124, decimal):
Error code from G3_XIST2, refer to the description regarding r0483.
Remedy: Acknowledge the encoder error using the encoder control word (G3_STW.15 = 1).
207575 <location>Drive: Motor encoder not ready
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The motor encoder signals that it is not ready.
- initialization of encoder 1 (motor encoder) was unsuccessful.
- the function "parking encoder" is active (selected using the encoder control word
G1_STW.14 = 1).
- the sensor module is defective.
Remedy: Evaluate other queued faults via encoder 1.
