13.1.1 CONNECTION OF MOTOR, DRIVE AND CONTROLLER

Since there are many types of drives, the definitions of interfaces are different, but they all have direction signal
cables and pulse signal cables, as well as the control signal and drive enabling signal. Many drives don't have this
signal, and it is possible to select the enabling mode by setting the drive parameters for some drives. The wiring
mode of pulse output signals:
1. Differential mode:
This mode is suitable for step drives with independent pulse and direction input and most servo drives. Use
this mode to get better anti-interference.
Note: Never connect any two of PU+, PU-, DR+ and DR-; otherwise, the pulse interface will be damaged.
2. Single end mode:
This mode is suitable for the step drives that the anodes of pulse and direction are connected together.
Note: It isn't suitable for the step drives that the cathodes of pulse and direction are connected
together.
Certain drives connect the anodes of optical coupling input, i.e. the common anode connection. At this moment,
connect the wires according to the figure below and do not connect PU+ and DR+ together; otherwise, the
pulse interface will be damaged.
The common cathode connection, i.e. connecting the cathodes of optical coupling input together, isn't suitable
for machine tool controller.
Please note that the PU_COM is only for the non-differential connection of the drive pulse; otherwise, the
controller will be damaged.
