Interface for stepper motor controllers (pulse/direction)

This interface can be used to connect the servo amplifier to a third-party stepper-motor
controller. The parameters for the servo amplifier are set up with the aid of the setup soft-
ware (electrical gearing). The number of steps can be adjusted, so that the servo ampli-
fier can be adjusted to the pulse/direction signals of any stepper-motor controller. Various
monitoring signals can be output. The analog input is inactive.

AGND (terminal X3/1) must be connected to the ground of the control system!
Observe the limit frequency!

Speed profile and signal diagram

Note:
Connecting an A quad B encoder offers more EMI supression.
