RS232 open/close loop controller, 40A, 12~48v, 800w, 1000w, 1500w BLDC MOTOR

1. Overview
MT-BLDCMD-40A is an intelligent brushless DC motor controller. It adopts 32-bit high-performance MCU,Advanced motion control algorithm is suitable to the outside of the quadrature encoder input to complete the open loop and closed loop speed, under the closed loop torque of motor sport. Controller with multiple analog input port, the pulse input port and digital I/O port, can through the special software to redefine its functions. Universal RS232 serial port communication, CAN bus, the USB communication, CAN be widely used in automation.
 
2. Product Features
1) Wide-range voltage input, 10-55V.
2) Intelligent PID control loop.
3) Working mode: Speed open-loop, close-loop control, torque close-loop control, position close-loop control.
4) External potentiometer, 0-5V analog quantity or pulse command control mode, RC (pulse width signal outputted by the receiver of aeromodelling remote control) control mode.
5) Safety forward & reverse control, four-quadrant operation, support regeneration.
Enable control function.
6) Enable control function.Maximum current control.
7) 4-way input port; the function can be defined as analog input, pulse input or digital input functions.
8) 2-way digital (MOS tube open-drain) output, Generally as 24V 1A output (maximum load capacity of 40V 1A), can be used to loosen the brake or other attachments.
9) Abnormalities like overcurrent, overheating, overvoltage and short circuit will start the protection function.
