7. Mechanical Dimensions
8. Power Supply
The driver can work normally with power supply range between DC12V to DV40V, it is
better to use unregulated DC power supply, or it is workable to use transformer + bridge
+ filter capacitance, the capacitance can be 1100 uF or so. Be reminded that the voltage
peak value not exceed 40V after adjusting current, otherwise the driver will be damaged.
It is recommended to use 24-36V DC power supply, it can avoid the voltage fluctuation
exceed the rate voltage range. MotionKing can supply the suitable DC power supply.
Using regulated switch power supply, please set the output current range to be the
maximum.
Attention:
1. Not to reverse the power positive and negative when connecting;
2. It is recommended to use non-stable power
3. The voltage not to exceed the max. when the electric net power supply is fluctuant.
4. When using unregulated supply, the current output rating must more than the driver
setting current by 60%. Using regulated power supply, must more than the driver’s
setting current.
5. In order to lower the cost, two or three drivers can share the same power supply.

9. Selection Microstep resolution and driver current
This driver uses a 6-bit DIP switch to set microstep resolution, dynamic current and standstill
current, details as below:
Microstep Resolution Selection
Microstep resolution is set by SW4, SW 5, SW 6 of the DIP switch as shown in the
following table:
Microstep
Steps/rev.(for1.8o motor) SW4 SW5 SW6
1 200 ON ON ON
2 400 OFF ON ON
4 800 ON OFF ON
8 1600 OFF OFF ON
16 3200 ON ON OFF
32 6400 OFF ON OFF
64 12800 ON OFF OFF
Current Settings
Peak current (A) SW1 SW2 SW3
0.21A OFF ON ON
0.42A ON OFF ON
0.63A OFF OFF ON
0.84A ON ON OFF
1.05A OFF ON OFF
1.26A ON OFF OFF
1.50A OFF OFF OFF
Note: Due to motor inductance, the actual current in the coil may be smaller than the
dynamic current settings, particularly under high speed condition.
