I、Summarize
Based on the original stepping motor driver, we developed the 20611D type stepping motor driver. This driver owns many advantages such as lower noise, higher efficiency, lower temperature rise, convenient settings, nicer running characteristic and so on.
II、The using and instruction of the motor driver
Input power wiring point:
Single external power supply link AC 50V-100V 3A
Warning: The value of the power supply shouldn’t be over this range.

Warning：Motor’s wires mustn’t be connected wrongly, Otherwise, the driver will be mangled.
Input signals
The inner interface circuits of the SH20611D are segregated by optically coupled isolators.
There are three connecting mode between the controller and the driver.

DIR：Input port of the direction signal. High/low level controls the CW/CCW of motor. The changing edge of the signal must be at least 2.5us later or earlier than the falling edge of CP;
FREE: Free signal (active low). when this input end is low level，there will be no holding torque of the motor.
CP：Pulse signal input. active by the falling edge，the highest response frequency can be 200kHz，low level pulse width should be not less than 2.5us。
Warning：Input signal must have enough current, (Currently, TTL, COMS signal are not drive firsthand). Otherwise, System can not run normally.
* phase current and subdivision number setting：
Shift switch is adopted to set phase current and subdivision number in CF20611D driver. There-into, Switch 5 is half phase-current (ON means full current, OFF means half), switch 6 is the setting of single or double pulse (ON show single pulse CP, DIR; OFF show double pulse CW,CCW). See Table2，Table3.After the subdivision of driver is set, the step angle in motor is equal to whole step angle divided by subdivision number. For example：if subdivision number is set to 18 and the motor is 2-phase，its subdivision step angle is 1.8°/18=0.1°。
Warning：shift switch ON=0，OFF=1.

III、Installation Dimension
Disperse heat by compelling structure is adopted, so when installing, please keep enough space to elimination of heat when the driver
IV. Signal indication
