stepper Motor driver Specification :
Input Power supply :
PWM constant current chopping ，two phase Sine wave output current
Suitable stepper motor
85，86，110,130 series two phase stepper motor
-10℃～55℃ 15～85%RH、No condensation. Non-corrosive, flammable, explosive, conductive gas, liquid and dust
－40℃～+55℃, ＜93%RH，No condensation, no frost
Microstep subdivision setting :
Users can set the driver Microstep by the SW1-SW5 five switches，total 28 micro-step. When you set the microstep , pls stop the driver working。The setting of the specific Microstep subdivision, please refer to the instructions of the driver panel figure .
Output current setting
Users can set the driver Microstep by the SW1-SW5 five switches. The setting of the specific Microstep subdivision, please refer to the instructions of the driver panel figure..
Double pulse setting
SW7 sets pulse mode, setting “on'' as double pulse mode, setting “off'' as pulse + direction mode.，CW+/CW is Clockwise ，CCW+/CCW- is Counterclockwise , need to confirm the wire of stepper motor 。
Automatic half current function
Users can set the driver half flow function by SW6. "OFF" indicates the quiescent current is set to half of the dynamic current, that is to say, 0.5 seconds after the cessation of the pulse, current reduce to about half automatically. "ON" indicates the quiescent current and the dynamic current are the same. User can set SW6 to "OFF", in order to reduce motor and driver heating and improve reliability.
Self test function
When SW1-SW5 is OFF , Inner of drive send 1K pulse to test whether the motor，wire，and self is normal。
PUL+ and PUL- are the positive and negative side of control pulse signal; DIR+ and DIR- are the positive and negative side of direction signal; ENA+ and ENA- are the positive and negative side of enable signal .
A+ and A- are connected to a phase winding of motor; B+ and B- are connected to another phase winding of motor. If you need to backward, one of the phase windings can be reversed .
It uses DC power supply，recommended working voltage is 110－220VAC，power is over 500W，voltage shouldn’t be over 230VAC and below 110VAC。
There are two indicator lights. Power indicator is green. When the driver power on, the green light will always be lit. Fault indicator is red, when there is over-voltage or over-current fault, the red light will always be lit; after the driver fault is cleared, if re-power the red light will be off.。
The size of motor driver is 180X76X130 mm，mounting holes is 185mm。Chest and upright installation are ok，we suggest upright installation。 During installation, it should be close to the metal cabinet for heat dissipation.
signal interface and sequence in time :
Inner electric circuit of motor drive :
Connection of Output alarm:
Note : OC is output of photoelectric isolation , Max voltage capability is 30VDC ,maximum saturation current is 100 MA motor driver .
Output optocoupler is not conducted under the normal working condition .
Interface connection and installing size :
This nema 51 step motor driver with lower noise, high accuracy, high efficiency and short circuit, comes from Weitong which is one of the leading manufacturers and suppliers in this field.
