Note: Correct installation of the screw is essential for fulfilling the EMC
requirements and for proper operation of the module.
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 encoder and resolver should be connected to the FEN-21 with a
shielded instrumentation cable, preferably with twisted pairs. See also
the encoder and resolver manual for additional requirements.
TTL encoder maximum cable length:
• 30 m with a 5 V encoder (0.5 mm
• 60 m with a 5 V encoder (two parallel 0.5 mm
• 100 m with a 10...30 V TTL incremental encoder
Resolver maximum cable length: 100 m
TTL encoder emulation maximum cable length: 100 m
Tightening torque is 0.3 Nm (2.7 lbf·in.).
Note: Do not route the encoder cables parallel to power (e.g. motor)
cables.
Programming
The FEN-21 is programmed through drive parameters. These parameters
must be checked and adjusted according to the encoder and resolver
data sheet. For further information, see the drive Firmware manual.
