Drive function description

Drive function	Instructions
Microstep subdivision setting	4 microstep subdivisions can be set for the Driver through 2 dial switches SW5~SW6. The Driver shall be stopped while setting subdivision. See driver panel instruction for microstep subdivision settings.
Output current setting	8 output currents can be set for the Driver through 3 dial switches SW1~SW3. See driver panel instruction for output current settings.
Automatic half -flow function	Automatic half current function can be set for the Driver through switch SW4. OFF means that quiescent current is set to half of operating current; ON means that quiescent current and dynamic current are the same. SW4 shall be set as OFF for general use to reduce heat generation of the motor and the driver and to improve reliability. About 0.3s after pulse train stops, current will automatically reduce 50%(actual value 55%) and theoretically, heat generation will reduce 65%.
Signal interface	PULis the negative terminal of pulse signal control; DIR is the negative terminal of direction signal; ENA is the negative terminal of enable signal; OPT is the positive terminal of pulse/direction/enable signal (5V public terminal).
Motor interface	A+ and A- connect to positive and negative terminals of A phase winding of stepper motor; B+ and B- connect to positive and negative terminals of B phase winding of stepper motor. When A and B phase windings are switched, the Motor direction will be reversed.
Power connector	DC power supply, operation input voltage range: 18V-36VDC, 24V DC is suggested
Indicator light	There is 1 green indicator light and 1 red indicator light on the Driver. The green one is power indicator light, it illuminates when the Driver is connected to power supply; the red one is failure indicator light, it illuminates when over-voltage or over-current failure occurs.Red indicator ight goes off after failure is eliminated. Failure ofthe Driver can only be eliminated by re-connecting to power supply and reusing.
Installation Notes	Dimensions of the Driver: 86x55x20.5mm, installation pitch of holes: 79mm. Both horizontal and vertical installations can be selected (vertical installation is suggested). The Driver shall be installed closely against metal cabinet for heat dissipation.
