Mounting
Warning! Before installation, switch off the drive power supply.
Wait for five minutes to ensure that the capacitor bank of the drive
is discharged. Switch off all dangerous voltages connected from
external control circuits to the inputs and outputs of the drive.
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 encoders should be connected to the FEN-11 with a shielded
instrumentation cable, preferably with twisted pairs. See also the
encoder 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
Absolute encoder maximum cable length:
• 25 m (0.5 mm
• 50 m (two parallel 0.5 mm
• 75 m with an external power source for the encoder
TTL encoder emulation maximum cable length: 100 m
Tightening torque is 0.3 Nm (2.7 lbf·in.) for the plugs.
