## Description

Specification: Item Type: Motor Speed Controller Voltage: DC 12-50V Current: Maximum 20A, recommended no more than 15A Size: 7.6 x 5 x 5cm / 3 x 2 x 2in(including heat sink)  Packing List:  1 * Motor PWM Speed Controller    Wiring Method: 1)GND: 12-50 VDC power supply negative 2)12-50 V: 12-50 VDC power supply positive 3)M+, M- are connected to two wires of DC motor, no need to distinguish  positive or negative. 4)PWM+: Positive terminal for external PWM signal and for MACH3 control cards,  negative terminal of PWM for PLC 5)PWM-: Negative terminal for external PWM signal and for MACH3 control cards,  negative terminal of PWM for PLC 6) NPN-E: Alarm NPN output transmitter pole. Connected to the GND for MACH3 cards. 7) NPN-C: Alarm NPN output collector pole. Connected to the P10 input terminal for MACH3 cards. 8) OC-ADJ-T: Over-current setting potentiometer. A letter corresponds to 2A, the maximum can be set as 20A.

## Features

- 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.
- Power input only supports DC input, with reverse-input protection, and the voltage range is DC12-50V.
- 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.
- 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
- 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
