Action: Check the connected position encoder: If further
error messages occur in conjunction with the
encoders, then eliminate their cause first.
Check the motor and encoder cable / screening
on motor and drive side. EMC malfunctions can
trigger the error.
Check the setpoint specifications / Movement
profiles of the controller: Do they contain
impermissibly high temperatures above the limit
value for acceleration monitoring (P06.07)?
Check whether the limit value for acceleration
monitoring was parameterised correctly - the limit
value (P06.07) should be at least 30% ... 50%
above the maximum acceleration actually
occurring.
In case of an angle jump in the position data
transmitted from the basic device - Acknowledge
error once.

Rotational speed / angle difference,
encoder 1 - 2
Cause: Rotational speed difference between encoder 1
and 2 of one µC outside the permissible range for
longer than the allowed time.
Angle difference between encoder 1 and 2 of one
µC outside the permissible range for longer than
the allowed time.
Action: Problem may occur if two position encoders are
used in the system and they are not “rigidly
coupled”.
Check for elasticity or looseness, improve
mechanical system.
Adjust the expert parameters for the position
comparison if this is acceptable from an
application point of view.
