3.1 Power connection
If your power output does not have a fuse or some other device that limits the
short-circuit current, place a properly sized fast-blow fuse (no more than 10Amps)
between the power supply and the drive to protect the drive and power supply. Between
the positive side of the power supply and the V+ of the drive.
Connect the positive terminal of the power supply to the V+ of the drive and the
negative terminal of the power supply to the V- of the drive.
!!! Please be careful not to reverse the connection, the drive damage caused by
the power supply is not guaranteed.
Choose the right power source.
Voltage
The chopper driver continuously changes the magnitude and direction of the voltage
at the winding end of the motor while detecting current to obtain accurate phase current.
If both high efficiency and low noise are to be guaranteed, the driver supply voltage is
