2000 ( step angle of 0.18 degrees)
4000 ( step angle of 0.09 degrees)
8000 ( 0.045 step angle )
- Input pulse mode: single pulse and double pulse optional
- Power supply : AC16V / 0.5A with AC20V ~ 40V / 4A groups
- Matching motor : 57-86 series two -phase hybrid stepper motors

Use step:
(1 ) Reference panel prompts you to set the number of segments required by the DIP switch at CP pulse can allow, try to use a larger number of segments ;
(2 ) Reference panel prompts , set via DIP switch motor phase current , and generally set the rated motor phase currents are equal , if we can drag the load , the motor can be set to be less than the amount ;
Phase current, but can not be set to be greater than the rated motor phase current ;
(3 ) Reference panel prompt , set the drive via DIP switches semi- streaming capabilities . Drive pulse signal is applied to stop about two seconds , it will automatically enter half current state, then the motor phase current is half runtime , in order to reduce power consumption and protect the motor. Choose whether to start the semi- streaming capabilities .
(4 ) Reference panel prompt , set the pulse mode ;
( 5) The reference panel prompt , connect the input signal line ;
(6 ) Reference panel prompt , connect electrical lines ;
(7 ) Reference panel prompt , connect the power cord ;
(8 ) after power was observed lights and electrical operation.

Input Signal Description:
Drive is the weak signal amplification provided by the computer control system for stepper motor can accept high current signal, the control system provides a signal to the driver are mainly to Xia Sanlu :
(1 ) pulse signal CP: This is the most important way to signal , because the principle of stepper motor drive control system is to take the pulse signal emitted into the angular displacement of the stepper motor , or : drive each accept a pulse signal CP, the step of driving the stepping motor rotation angle , the rotation speed is proportional to the CP and the frequency of the stepper motor , the number of pulses CP determines the rotation angle of the stepping motor . Thus, the control system via a pulse signal CP can achieve the purpose of motor speed and positioning .
( 2) The direction level signal DIR: This signal determines the direction of rotation of the motor. For example , this signal is high when the motor is rotated clockwise , the signal is low , compared with the motor in the reverse direction of rotation counter-clockwise. Such commutation mode , which we call single-pulse mode . In addition , there is a double pulse commutation mode : The drive accepts two pulse signal ( labeled as CW and CCW), when one way ( such as CW) when there is a pulse signal , the motor runs forward , while the other way ( such as CCW) have when the pulse signal , the motor running in reverse direction .
Both ways can be selected by setting DIP switches.
(3 ) Offline signal PD: This signal is optional signal is not necessary to use , and use only in some special cases, this ends a 5V input level, the motor is no torque state ; this side is high or dangling not connected , this function is disabled , the motor can be run properly if the user does not use this feature , you can just float this end
