3.3.5 Adjusting the Encoder Supply Voltage
The encoder power voltage at the encoder input part must be between 4.75 and 5.25 V. If
the encoder cable is long, adjust the encoder supply voltage by setting the following pa-
rameter.
Cn-2C
Encoder Power
Voltage
Adjustment
Unit: 0.1 mV Factory Setting: 52500 For Speed/Torque
Control and
Position Control
The following values apply to standard cables:
Length of cables
Encoder
3 m 5 m 10 m 15 m 20 m
15-bit absolute encoder 55000 57000
12-bit absolute encoder
Incremental encoder
52500 54000 55500
Note that the system may fail to operate normally or break down if the setting is too high or
too low.
