SH-203A used by the US sub-drive high-performance dedicated micro-step away from the computer control chip, the number of segments can be designed according to user needs, open microcomputer according to user requirements to functional design to the drive, consisting of minimum control system.

The controller is suitable for small and medium sized drive any two-phase or four-phase hybrid stepper motor. As a result of new bipolar constant current chopping technique, the high-precision motor running, small vibration, low noise, smooth operation.

Feature

VCC +, GND terminal for external DC power supply voltage range of + 20V ~ + 40V, should not exceed 40V, to avoid damage to the module

CP + CP- step pulse input (rising edge, duration> 10μS), the chopper frequency is greater than 35KHZ, the input signal is compatible with TTL

Subdivision Optional: 1 / 2,1 / 4,1 / 8,1 / 16,1 / 32,1 / 64, the drive current is set by the switch

A +, A- end of Phase A, B +, B- end of the motor phase B

CW +, CW-: direction of the motor control by controlling the terminal level can change the motor running direction, REST +, REST-: emergency stop reset

No CP pulse current automatically reduced by half, the output phase current 0.11,1.28,1.62,1.88,2.28,2.52,2.95,3.5A can drive two-phase or four-phase hybrid stepper motors, optical isolation signal input logic signal input current 10mA-25mA, falling edge of the pulse duration is greater than 5us. Cooling; natural or forced air cooling, use of the environment; avoid dust and corrosive gases.  temperature; 0 ° C- + 50 ° C, and humidity; 40- 89% RH.
