3.2 Power supply input
The power supply of the driver can be both AC power and DC power, and the input voltage range is
20V~80VAC or 24V~100VDC.
Please do not connect to commercial electricity(220VAC) directly!
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.
Stepper servo has a higher speed and torque output than ordinary stepper. Therefore, if you want to
get better high-speed performance, you need to increase the power supply voltage of the driver.
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. 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 and
superimposed on the driver circuit and input power supply.
Pay attention to the setting of acceleration and deceleration time to protect the driver or power
supply.
When the driver is powered off, you will see the driver's LED indicator on when the load is pulled to
make the motor move, which is also affected by this.
