Typical Connection Example

1. Connection method of single potentiometer duty cycle/closed-loop speed control with incremental motion control

The working process of using potentiometer speed regulation in jog control mode is as follows: press B1, the motor rotates forward, and use potentiometer speed regulation; B1 pops up, the motor stops; When the motor stops after the forward limit is reached, pressing B1 again is ineffective; Press B2 to reverse the motor and use the potentiometer to adjust the speed; B2 pops up, the motor stops; When reversing the limit, the motor stops, and pressing B2 again is ineffective.

2. Dual potentiometer duty cycle/closed-loop speed regulation connection method

The dual potentiometers of this connection can be divided into independent control and cooperative control. When it is independent control, the forward and reverse rotation of the motor are regulated separately. The motor can be enabled and the direction of rotation can be switched by the switch, and the forward and reverse rotation is limited by the limit switch; When coordinating gear control, set the voltage of potentiometer 2 as the reference voltage and adjust the voltage of IN1 and IN2 for motor speed and direction adjustment.

3. Single chip PWM signal duty cycle/closed-loop speed control method connection

The working process of this connection method is: 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 and emergency braking.

4. Connection of single-chip microcomputer pulse signal position control

The working process of this connection method is: connect the power supply ground of the microcontroller to the COM port of the driver module; IN1 is connected to the IO1 of the microcontroller to determine the number of pulses used for motor position control; VO is connected to the IO0 of the microcontroller to complete signal control; IN2 and IN3 are connected to two IO ports of the microcontroller to control the forward and reverse rotation of the motor and emergency braking. Note: The VO output is a 3.3V logic level. If the microcontroller does not accept the 3.3V logic level, it needs to be converted to a 5V logic level.

5.Connection method of PLC analog signal duty cycle speed regulation

The working process of this connection method is: IN1 is connected to the AO port of the PLC for speed regulation; IN2 and Y2 of PLC control the forward rotation of the motor; Connect IN3 to Y1 of PLC to control motor reversal.

6. Connection method for PLC pulse signal position control

The working process of this connection method is: IN1 is connected to Y3 of the PLC to determine the number of pulses used for motor position control; IN2 and IN3 are connected to two IO ports of the microcontroller to control the direction of the motor and emergency braking; After connecting a 240 Ω resistor in series with VO, an optocoupler is indirectly connected to COM. The optocoupler output is connected to+24V and X1 of the PLC, which is used to feedback the completion signal to the PLC.

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.
