Drive with encoder/safety encoder

If an encoder/safety encoder is mounted onto the drive, then this must be disassembled before performing motor and brake maintenance.

WARNING

Loss of the safety functions due to a faulty mechanical connection between the motor and the safety encoder.
Severe or fatal injuries.
  • To ensure the exclusion of any faults in the mechanical connection between the motor and the safety encoder, comply with the following points in accordance with EN 61800-5-2:
  • Perform a proper disassembly/assembly according to the corresponding documentation.
  • Replace worn or damaged components.
  • Adhere to the tightening torques specified in the corresponding documentation.

Note that the work steps for a safety encoder differ from an encoder without safety technology (standard encoder).

First, check the FS logo on the motor nameplate to ascertain whether a safety encoder is installed (see chapter FS mark).
