Page 15: Adapter For Incremental Encoders
The adapter records the data between the encoder and drive and makes it available to the PNOZ ms2p TTL (Coated Version) via the RJ45 socket. Pilz supplies complete adapters as well as ready-made cable with RJ45 connector, which can be used when making your own adapter. The range of products in this area is con- stantly being expanded. -

If the "Overspeed" output (see red marking) = "0", either the maximum permitted speed has been exceeded or the speed monitor has recognised a fault. "Overspeed" output = "0" must lead to the shutdown of the relevant axis.
