3.2 Power supply input

The power supply of the driver is DC power, the input voltage range is between 18V

~ 48V.

Do not reverse the polarity of the input power ! ! !

The working mode of the driver is constant current control. When working, the

driver outputs the input power supply to the motor in the form of PWM chopper.

Therefore, the power input can affect the performance of the drive.

Power selection reference:

Voltage:

Stepper motor has the characteristics of torque decrease with the increase of motor

speed, and the input voltage will affect the amplitude of high-speed torque

reduction. Properly increasing the voltage of the input power supply can increase

the output torque of the motor at high speed.

Therefore, if you want to get better high-speed performance, please increase the

power supply voltage of the driver. For low-speed applications, choosing a slightly

smaller voltage can appropriately reduce the heat of the motor.

Current:

The working process of the driver is to convert the input high-voltage and low-

current power supply into the low-voltage and high-current at both ends of the

motor winding. Therefore, the current of the power supply will be lower than the

current value that the driver outputs to the motor.

In actual use, the appropriate power supply should be selected according to the

motor model, load torque and other factors.

The effects of regeneration voltage:

When the stepper motor is working, it also retains the characteristics of the

generator.When decelerating, the kinetic energy accumulated by the load will be

converted into electrical energy through the drive circuit. This part of the energy will

be superimposed on the driver circuit and input power supply, causing protection of

the driver circuit and power supply.

When setting the motor running command, pay attention to the setting of

acceleration and deceleration time.

In addition, when the driver is powered off, the driver's LED indicator will be on

when the load is pulled to make the motor move. This phenomenon is also related

to the above reasons.

Power selection:

The output current of the switching power supply is not less than 7A, and the power

is not less than 200W.
