4.3 Half / full flow selection
DIP SW4 is used to set the static current value when the motor is stopped
Off means that when the driver's power-on pulse stops, the driver switches the current output to the
motor to half (half current) when it is rotating;
On means that when the driver's power-on pulse stops, the driver maintains the same current output to
the motor as the rotation (full current) ). In general use, SW4 should be set to off, so that the heat of the
motor and driver is reduced, and the reliability is improved.

Solutions
Motor does not
work
Power indicator is off
Check the power supply circuit for normal
power supply
The motor rotor is locked but the
motor does not work
Pulse signal is weak; increase the signal
current to 7-16mA
The speed is too slow
Select the right micro-stepping
Driver is protected
Solve the alarm and re-power
Enable signal problem
Pull up or disconnect the enable signal
Command pulse is incorrect
Check whether the upper computer has
pulse output
The steering of
motor is wrong
