Installation and Wiring
Connect an Encoder
Use twisted-pair, individually-shielded cable to connect encoders and
drives. Refer to your encoder or drive manual for proper cable type
and maximum length.
IMPORTANT
The drive or encoder and the MSR57P power supply reference
must be the same.
IMPORTANT
The MSR57P relay has an internal resistance of 600Ω on each
of the encoder signals to achieve an equivalent load resistance
of 100Ω if used with a drive that has 120Ω internal terminating
resistors. Your encoder may require that the equivalent load
resistance be 100Ω or greater. Refer to your encoder user
manual to make sure the equivalent termination resistance
does not exceed the encoder signal loading specification.
ATTENTION
Do not use external terminating resistors with PowerFlex or
Kinetix drives. Doing so may cause permanent damage to the
drive.
The following illustrations show simple examples of how to connect
an MSR57P relay with an encoder, with or without a drive.
