Number
Cause
Check and action
1: Item
Fast set position change leads to
acceleration that cannot be
performed
Check the current set acceleration against the
maximum permitted acceleration in the drive
controller (E64, E69) and reduce the set value
change in the controller or change the motor
type if necessary
2: Velocity
Fast set velocity change leads to
acceleration that cannot be
performed
Check the current set acceleration against the
maximum permitted acceleration in the drive
controller (E64, E69) and reduce the set value
change in the controller or change the motor
type if necessary
