7.2.11
Error message ’Encoder lost position’
7.2.12
Error message ’Encoder Reed error’
Message no. / Message
8 / ’Encoder lost position’
Type / Motor action
Unrecoverable error / Motor is set in Passive mode.
Error condition
The absolute multi turn encoder (H3/H4) has lost the position.
Possible cause of this error
•
The reset of the encoder can be caused by a firmware update.
•
The battery level is low and the encoder cannot remember the
position.
Solutions to avoid error
Hints to optimise the battery lifetime:
1. Avoid to place the motor in an environment with high tempera-
tures.
2. Set the running and especially the standby motor current as low
as possible in order not to heat up the motor unnecessarily.
3. Keep the external power applied as much as possible.

How to return to normal
operation
•
Reset the position (special command 354 in register 24), clear
the error bit(s) in register 35 or cycle the power.
•
If the battery level is low, this error will re-appear every time after
power has been off for a while. In that case, the motor must be
returned for service.
•
A the cause have been a encoder firmware update from an older
version an encoder calibration may probably rescue the motor
from this error state. See

Bit 8
Message no. / Message
9 / ’Encoder Reed error’
Type / Motor action
Unrecoverable error / Motor is set in Passive mode.
Error condition
•
The absolute multi turn encoder (H3/H4) has detected a wrong
sequence in the positioning algorithm.
•
This error also occurs after firmware update.
Possible cause of this error
•
This can be caused by a mechanical shock on the shaft or an ex-
ternal magnetic field.
•
Because the encoder has been reset during a firmware update.
Solutions to avoid error
•
Do not place the motor inside a strong magnetic field.
•
Do not expose the shaft or the motor for mechanical shocks.
How to return to normal
operation
•
Reset the position (special command 354 in register 24), clear
the error bit(s) in register 35 or cycle the power.
