AQMD3630NS-A DC motor driver features:
Support motor voltage 9V~36V, rated load current 30A (can work for a long time), 30A fuse
Support single/dual potentiometer, 0~5V analog signal and TTL level, -5V~+5V differential analog signal and RS485 control mode
Support pulse width speed regulation (pressure regulation), torque control (steady current), self-test closed-loop speed regulation (steady speed), external tachometer generator closed-loop speed regulation (steady speed) a variety of speed regulation methods
Motor current PID regulation and control, current control accuracy 0.15A, maximum starting/load current, brake (brake) current can be configured separately; Support motor overload and blocked current limit to prevent overcurrent damage to the motor; Support constant current braking (brake), short motor braking time and small impact force; The direction switching process is automatically controlled by current, quickly and without shock vibration
The built-in high-power brake resistor can provide 6A continuous braking current, which can brake or reverse frequently with high current
Support motor forward and reverse bidirectional speed regulation, two potentiometers can be used to adjust the forward and reverse speed speed of the motor separately; The forward/reverse speed can be preset and stored through the serial port, and the start-stop and direction can be controlled by switch or button
Support motor forward and reverse limit, can be connected to two stroke switches to forward and reverse limit
Support motor commutation frequency (speed) self-measurement and speed stabilization, support motor stall detection/stall limit stop
Support RS485 multi-machine communication, support MODBUS-RTU communication protocol, facilitate a variety of controllers (such as single-chip microcomputer, PC or PLC) communication control, support communication interruption shutdown protection
PWM frequency of 18kHz, this frequency is close to the upper limit of human ear hearing, and the motor does not shout when adjusting the speed
Extremely small PWM dead zone, only 0.2us, PWM effective range: 0.1%~99.9%
All interfaces ESD protection for complex environments
Using ultra-thick aluminum alloy large radiator case, built-in cooling fan, the heat dissipation is very good.
The size is 16.0cm×9.6cm ×5 .6cm. The aperture of the mounting hole is 4mm, and the distance from the center of the mounting hole to the side is 9mm
