Q : GD20-EU will turn on the fan as long as it is running, how to stop the fan?
A: There are two ways: by setting P08.39 function code or combining with sleep function._x000D_ For example, set P00.05=1, P01.19=2,P05.01=1. S1 is the forward rotation (Zero speed) and S2, S3, S4 multistep speed,S1 is always bridge with the GND and the fan is always in operation. Use S1 and GND to stop the fans. P01.19 turn to 2 and the lower Hz will be 1Hz. Then the inverter when goes to 0 goes to sleep mode.
