1、Power input only supports DC input, with reverse-input protection, and the voltage range is DC12-50V. 2、By setting, it can supports motors with multiple parameters.Adjust OC-ADJ-T for potentiometer matching.Maximum matching current 20A.General coarse adjustment, factory setting is at about 2A. 3、When the motor is controlled manually and independently, the PWM fundamental frequency of the motor can be controlled by the jumper, which can be used to match different motors and to minimize the noise at different speeds. Fundamental frequency has 3 le 4、There are two ways to control the motor: whether to independently and manually control motor by the jumper or to control the motor by external PWM signal connection with control card or PLC. External PWM input requirements are level of 3.5-12V VPP, frequ 5、The controller has alarm output function. When the motor is stalling, it can send a signal to the control card or PLC, let the control card or PLC stop and other related actions.
