Specification and Description / Product Characteristic This closed-loop speed controller is designed with the latest type IGBT and MOS power devices. It takes advantage of DC brushless motor’s Hall signal to double frequency for closed-loop speed control. PID control links with the speed controller. The control system is stable and reliable, especially at low speed, it always can reach the maximum torque, The speed control range is from 150 to 20000rpm. PID speed, current double loop regulator Electrical stop to ensure the quick action Over load ratio larger than 2, the torque can always...

Terminal Connection Hall signal A phase input Hall signal B phase input Hall signal C phase input Hall signal power line Terminal Name CW/CCW terminal Stop/Start terminal Brake terminal Analog signal input terminal Speed output terminal Alarm output terminal +5V power output terminal Signal ground Built-in potentiometer R-SI : Adjust the motor speed gain, which can be adjusted from 0~100%. Built-in potentiometer R-CS : Maximum protection current setting, built-in potentiometer can be set 0%~100% continuous current protection.

Speed Adjustment Method This driver provides the user below three-speed control method: Inner potentiometer speed adjustment : Rotate the potentiometer on the driver panel counterclockwise, the rotate speed decrease, rotate the potentiometer on the driver panel clockwise, the rotate speed becomes higher. Please make sure the potentiometer is set in the minimum state when you use external input mode to adjust the speed. External input adjustment : Connect the terminals of the external potentiometer to the GND and +6.25v terminal, connect the regulator terminal to SV, then you can adjust the...

Functions and Usage / Communication Method Brake the Motor to Stop (BK) You can break the motor to stop if need. The motor will run when the terminal “BK” not connects to “GND”, but if you connect these two terminals, the motor will stop quickly. And the motor stopping time will be decided by inertia and load adding on the motor. If you are not necessary to stop the motor quickly, please DO NOT use this function, cause it has some electrical and mechanical impact on the motor and driver. Speed Signal Output (PG) The speed pulse output port is 0C, output 30V/10mA max. You can connect with a...

Communication Method support multiple communication rates (see parameter table for details). If the communication mode control motor is required, it must be performed under the MBUS control mode and the internal control terminal. Function parameters support 03H multi-register read, 06H single register write.
