Note: Before mounting the module, set the supply voltage
jumpers as described above.
• Insert the module carefully into the option slot until the retaining
clips lock the module into position.
• Fasten the screw (included) to the stand-off.
Note: Correct installation of the screw is essential for fulfilling the
EMC requirements and for proper operation of the module.
Wiring
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
supply)
• 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.) for the plugs.
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.
