Uncontrolled motor motion due to incorrect commutation
Incorrect commutation can result in uncontrolled motor movements.
• Only carry out the work associated with replacing the encoder if you have been
• When replacing an encoder, ensure the correct commutation setting.
Note
General mechanical conditions
Take into account the permissible velocity, limit frequency of the encoder and Control Unit.
When configuring, mounting and adjusting the encoder refer to the appropriate
documentation issued by the manufacturer!
Mechanical integration of the encoder
The mechanical integration of an encoder is defined by certain influencing factors, e.g.:
● The requirements specified by the encoder manufacturer (mounting specifications,
ambient conditions)
● The closed-motor control (commutation) requires an adequately accurate connection
between the motor and encoder without any play
