Three-line control mode 1
(1) When need to run, must be closed DIn terminals first, implemented by DIx or DIy pulse rising to
realize the motor forward or reverse control;
(2) When need to stop, it should be done by disconnect DIn terminal signal;
(3) The DIx, DIy, DIn is DI1 ~ DI5, HDI1 multi-function digital quantity input terminals, DIx, DIy for
pulse effectively, the DIn of level effectively;

(1) When need to run, must be closed DIn terminals first, produced by DIx pulse rising along the
motor run signals, DIy status produce motor rotating direction signals.
(2) When need to stop, it should be done by disconnect DIn terminal signal.
(3) The DIx, DIy, DIn is DI1 ~ DI5, HDI1 multi-function input terminals, DIx for pulse effectively, DIy,
DIn for level effectively.
