4-102 ECODRIVE03 DKC**.040, DKC**.100, DKC**.200 ECODRIVE03 Drive Controllers
Control inputs for stepper motor mode (SM1+, SM1-,
SM2+, SM2-)
Note: The control of the stepper motor interface with dierential
signals is preferable to single-channel control because the
noise immunity of dierential signals is better than zero-
referenced signals.
