9.13.2 Connection to stepper motor controllers (step and direction)
You can connect the servo amplifier to a third-party stepper-motor controller. Parameter set-
ting for the slave amplifier is carried out with the aid of the setup software (electronic gear-
ing). The number of steps can be adjusted, so that the servo amplifier can be adapted to
match the step-direction signals of any stepper controller. Various monitoring signals can be
generated.
Using an A quad B encoder provides better EMC noise immunity.
