In pulse & direction mode, PLC sends stream of pulses with direction signal to modify motor position incrementally. This is the de-facto standard for driving stepping motors. However with Granite Devices drives, any motor type can be operated with step & direction interface. | In pulse & direction mode, PLC sends stream of pulses with direction signal to modify motor position incrementally.

| − | Drawback of this method is the extra work of porting SimpleMotion C library to PLC. If you implement SimpleMotion for PLC, and wish get good karma by contributing your work to the community, please [[Granite Devices support|contact us]]. | + | Drawback of this method is the extra work of porting SimpleMotion C library to PLC.
