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

BMD-40DIN ver.2 is a driver designed to control torque, speed, direction, acceleration and deceleration of a DC brush motor with a power of up to 1000 W.

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.
