L1 and L2 are AC input terminals, and the input voltage level is 115 / 230VAC;
I1 and I2 are start stop signal terminals, and I2 is the low end. When disconnected, the motor runs, and when connected, the motor stops;
P3 p2 p1 is the external potentiometer terminal, P3 is the signal power supply, P2 is the signal input end, P1 is the low end of the signal, when using the external signal 0-10V control, F - and P2 can be used as the input end, and the input signal is an isolation signal;
F + F - is the motor excitation terminal, and the maximum current is 1a,
