Wiring
Warning! You can connect a motor temperature sensor to the encoder
module only if there is double or reinforced insulation between the live
parts of the motor and the sensor. The module does not provide a safe
isolation from the drive. Refer to the drive manuals for more information.
The encoders should be connected to FEN-31 with a shielded
instrumentation cable, preferably with twisted pairs. See also the
encoder manual for additional requirements.
Maximum cable length for encoders:
• 300 m for differential push-pull HTL encoders
• 200 m for single-ended push-pull HTL encoders
• 100 m for open collector / open emitter HTL encoders
Tightening torque is 0.5 N·m (5 lbf·in) for the plugs.
Note: Do not route the encoder cables parallel to power, eg, motor
cables.
Programming
FEN-31 is programmed through drive parameters. These parameters
must be checked and adjusted according to the encoder data sheet. For
further information, see the drive Firmware manual
