2、智能控制Intelligent Control (1)软启动:电机低速慢启动,防止电源冲击 It will start up in lower speed, than up. (2)脉宽调速:可以通过控制脉冲宽度调节电机转速It contain speed controller if it connected to impulse controller (3)过流保护功能:负载过重时,电路自动保护 The current will shut down if the motor is over current or over load 3、 故障与检查Malfunction & Self-check 在电机控制板正常情况下,电机不转。请检查以下情况: If the motor can not run, please check the following things:
