1, the direction of the stepper motor is opposite to the requirements, how to adjust?

You can change the direction signal of the control system, or you can change the direction by adjusting the wiring of the motor.

details as follows:

For two-phase four-wire motors, simply swap one of the motor wires into the drive, for example, swap A+ and A-.

2, the motor is normal at low speed, when the frequency is slightly higher, there is a stall phenomenon?

This situation is mostly caused by the power supply voltage applied to the driver is not high enough; if the input voltage is increased, it can solve this problem, but it can’t be higher than the highest voltage marked on the power supply end of the driver; otherwise it will cause the drive to burn. For example, if the original power supply voltage is 24V DC; it can be connected to 36V.

3. After the driver is powered on, the motor is shaking; can’t run?

In this case, first check if the winding of the motor and the driver are connected incorrectly; if there is no error, check if the input frequency CP is too high.

4. How is the step angle of the motor calculated after subdivision?

For two-phase and four-phase motors, the stepped angle of the subdivision is equal to the full step angle of the motor divided by the number of subdivisions. For example, the subdivision number is set to 2 to drive a 0.9 degree/1.8 degree motor, and the subdivision step is The angle is 1.8/2=0.9 degrees; if the subdivision number is set to 8, the motor is driven by 0.9 degrees/1.8 degrees, and the subdivision step angle is 1.8/8=0.225 degrees
