Figure 6.
Connect the boards to the control board by means of the 34-wires flat cable and the
control board to the host PC.
Connect the stepper motor to the P3 and P4 connectors
Put jumpers on JR1, JR2, JR3
Apply 5 V to P1 connector
Apply motor voltage VS to P2 connector
Launch the PractiSPIN™.spmd program on the host PC
Click on "connect to ST7 hardware" and perform calibration
–
–
Click done and enter "speed control mode" or "indexing mode"
Click on calibrate zero and verify that VTP3 is zero.
Click on calibrate max and set the maximum current, corresponding to 100%
current setting in the PractiSPIN™.spmd software, adjusting the RV1 trimmer on
the target board until the voltage on VTP3 corresponds to the motor current. The
relationship between voltage/current is V = 0.165 I
