Setting the supply voltage X301
Warning! Selecting the wrong supply voltage may damage or
break the encoder.
The supply voltage for TTL encoders can be selected by vertically
mounted jumpers as described by the following figure.
TTL Encoder (X31) TTL+ Encoder (X32)
+24 V
Note: If an external power supply is used, the appropriate jumper
must be removed.
Note: If another FEN interface's TTL emulation output is
connected to TTL input, the appropriate jumper must be removed.
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.
+5.5 V +5.5 V +24 V
