When there is vibration source (such as a driller) close to the installation position, please use a vibrating absorber
or a vibration resistant rubber gasket.
When multiple drives are installed in the control cabinet, please pay attention to reserve enough space for
sufficient heat dissipation. If necessary, you can configure cooling fans to ensure good heat dissipation conditions
in the control cabinet.
3. Drive Port and Connection
3.1 Port function description
connect two terminals of
motor’s phase-B winding
connect two terminals of
motor’s phase-A winding
3.3 ~ 24V level
compatible
Direction input interface
3.2 Power supply input
The power supply of the drive can be both AC power and DC power, and the input voltage range is 24V~50VDC.
Input power polarity should not be reversed!!!
The drive
’
s work mode is constant current control. The drive output the voltage to motor by changing the input
power into PWM chopping wave when it is working. In this case, the input power will affect the performance of
drive.
Power selection reference:
Voltage:
The stepper motor has the characteristic of torque decreasing as the motor speed increases, and the voltage of
the input power supply will affect the declining amplitude of the motor torque at high speed. Increasing the
voltage of the input power supply appropriately can increase the output torque of the motor at high speed. And
