How to Use:
1. Before using, please adjust the external speed knob to 0 to avoid generating instantaneous large current and damaging the controller.
2. The rear wiring terminal AC indicates the AC input voltage, M+ and M? indicate that the DC power output is connected to the DC motor, and P1 and P2 indicate the emergency stop terminal. When P1 and P2 are shorted, the motor stops running.
3. This product uses a built in tube for overcurrent or short circuit protection. If it is fused, please replace it with a tube of the same specification. The panel action switch only controls the action
