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.
