5 / 10 page  GS-D500A CONNECTORS PINS DESCRIPTION CONNECTOR J1 J1-1 Phase A output J1-2 Phase B output J1-3 Phase C output J1-4 Phase D output J1-6 Ground CONNECTOR J2 J2-1 Motor Supply Voltage J2-3 Auxiliary Supply Voltage (+12V) J2-2,4 Ground CONNECTOR J3 Pin Function J3-1 Step clock isolated input (see fig. 3): this is a logic input that performs the step function, i.e. on every transition of this input the motor is moved one step in the proper direction. J3-2 Direction isolated input (see fig. 4): the logic state applied to this pin decides the rotation direction of the motor shaft. J3-4 Microsteps/step rate remote program- ming (SW1). J3-5 On board +5V output J3-6,7 Return path for on board +5V output J3-8 Disable input (see fig. 6): a logic high level applied to this input causes the power driver outputs to float. This condi- tion allows the manual positioning of the system. Care must be used when this input is activated because the detention torque is lost. J3-9 Optocoupler supply voltage J3-10 Zero current control isolated input (see fig. 5): when activated the phase current is reduced to zero J3-12 Microsteps/step rate remote program- ming (SW2) J3-13 Fault logic output (see fig. 9): this ouput is at a low logic level whenever an anomalous condition is detected. J3-15 Microsteps/step rate remote program- ming (SW3) Figure 3. Stepclock input circuit Figure 4. Direction input circuit 5/10 GS-D500A |
