characteristic use

1. Connection method of single potentiometer duty cycle speed control jog control

When using a potentiometer for speed regulation in the jog control mode, the triggering mode should be configured as jog mode. The working process is as follows: switch K1 is closed, the motor rotates forward, and the potentiometer is used for speed regulation; K1 disconnected, motor stopped; When the motor stops after the forward limit is reached, closing K1 again is ineffective; K2 is closed, the motor is reversed, and the potentiometer is used for speed regulation; K2 disconnected, motor stopped; When reversing the limit, the motor stops, and closing K2 again is ineffective.

2. Connection method for PWM speed regulation of microcontroller

This connection can achieve motor speed regulation through the PWM signal of the microcontroller: Connect the power supply ground of the microcontroller to the COM port of the driver module; The IN1 pin is connected to the PWM output of the microcontroller for speed regulation; IN2 and IN3 are connected to two IO ports of the microcontroller to control the forward and reverse rotation of the motor.

3. PLC simulation voltage PWM speed control method connection

This connection can achieve motor speed regulation through PLC analog signals, switch motor rotation direction through relays/transistors, and limit forward and reverse rotation through limit switches. When the analog AO voltage value is 0V, the motor stops running; When the AO voltage value is 0-10V, the output duty cycle is proportional to the AO voltage value.

4. Connection method of dual potentiometer duty cycle speed regulation

This connection can be used to adjust the speed of the motor in both forward and reverse directions using a potentiometer. The motor can be enabled and the direction of rotation can be switched by a switch, and the forward and reverse directions can be limited by a limit switch.

5. Method for preset forward and reverse speed self-protection control

The working process of this self-protection contact control method is as follows: press B1 once to make the motor rotate forward, press B3 once or until the forward rotation limit switch triggers the motor to stop, or press B2 once to make the motor rotate in reverse; Press B2 to reverse the motor, press B3 or until the reverse limit switch triggers the motor to stop, or press B1 to make the motor rotate forward; B3 is the forced stop button. During the movement, regardless of whether the motor rotates forward or backward, the motor can be stopped by pressing the forced stop button B3.

If there is significant environmental interference, a 104 capacitor can be connected in parallel between AI1 and COM, as well as between AI2 and COM. If using a battery to power the driver, it is recommended to connect a 10A fuse in series with the power interface.

6.485 Multi site Control Connection

The 485 communication lines of each drive are connected in parallel in the A-A and B-B directions, followed by a 485 master station. The 485 master station independently operates each drive based on the slave station address configured by the drive. The address configured for each drive should be unique and cannot be duplicated with other drives.

sample program

Provide PC sample programs (including source code) that can be used to configure parameters, debug motors, or for secondary development.

Special Features:For high-power motors (usually with no-load current above 0.5A), no speed measuring device is required, and this drive can directly measure the commutation frequency of the motor commutator. The speed of the motor is calculated by dividing the commutation frequency by the number of commutation times the motor rotates once, and then multiplying by 60 (motor speed=60 * commutation frequency/number of commutation times the motor rotates once). Based on the self testing speed function, this driver can achieve locked rotor judgment and speed stabilization function (i.e. when the load changes and the speed changes, the driver will automatically adjust the speed to the previous speed).
