BMD-40DIN ver.2 - DC brush motor controller

BMD-40DIN ver.2 is a driver designed to control torque, speed, direction, acceleration and deceleration of a DC brush. There are current limiting and second speed functions.

BMD-40DIN ver.2 provides adjustable current limiting function to protect the motor from overload. There is a brake control function. The function of switching during operation to a second preset speed using an external discrete signal has been implemented in the device.

Control methods:

 - analog speed control;
 - analog torque control.

Motor speed and output torque control signals:

 - built-in potentiometer;
 - external potentiometer;
 - analog signal 0...10 VDC;
 - analog signal -10...+10 VDC;
 - analog signal 4...20 mA;
 - PWM signal.

Discrete control signals:

 - START - start and stop of the motor;
 - DIR - rotation direction;
 - BRAKE - brake control;
 - SPEED 2 - switch to second speed;
 - HARD_STOP - emergency motor stop.

BMD-40DIN ver.2 driver performs the following functions:

 - start and stop a DC brush motor using a button at the front panel of the driver or an external signal;
 - analog speed and torque control of a DC brush motor;
 - switching to a second preset rotation speed on an external signal. The second speed is set with the built-in potentiometer;
 - control the direction of motor rotation with a button on the front panel or an external signal;
 - motor brake control;
 - setting the ratio of acceleration and deceleration;
 - motor overload protection with adjustable rated current value;
 - user setting of motor stop option: with the motor rotor closed to itself or with the motor rotor open;
 - short circuit protection;
 - emergency stop of a DC brush motor «HARD STOP» in case of opening of the electrical protective circuit;
 - temperature protection of power stages.
