Tab. 2-32:
Set according to the motor (encoder).
Prepare an encoder's power supply (5 V/12 V/15 V/24 V) according to the encoder's output voltage.
When the encoder output is the differential line driver type, only 5 V can be input.
NOTE The SW2 switch is for manufacturer setting. Do not change the setting.
