adjusted in range 4...12 V
the resolver must be such that sine and cosine signals remains in
range 2...7 V
TTL Encoders
The FEN-21 is compatible with TTL incremental encoders with
1...65535 pulses / rev and supports reference mark.
Setting the supply voltage X301
The supply voltage for the TTL encoder can be selected by
vertically mounted jumper as described by the following figure
TTL Encoder (X51)
+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.
