NOTICE
Destruction of the encoder electronics
Operation of a 5 V encoder on the 24 V encoder supply may result in the destruction of its
electronic components!
Make sure that you can operate the connected encoder on a 24 V power supply (e.g. HTL
encoder). This setting can be set in the expert list of the drive in parameter p0400 and in the
following parameters.
