To make the boards operative, perform the following simple steps:
●
●
●
●
●
●
●
●
If the internal reference of SPMD150STP is used, connect jumpers JR1, JR2, JR5, JR6; in
this way the motor current is fixed and no more controlled by PractiSPIN™.spmd SW.
Figure 8.
Connect them to the control board by means the 34-wire flat cable and the control
board to the host PC
Connect the stepper motor to P3 and P4 connector
Put jumpers on JR1, JR2, JR3A, JR3B
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 in "speed control mode" or "indexing mode"
Click on calibrate zero and trim R18 on control board until voltage on VREFA and
VREFB is zero.
Click on calibrate max and set the maximum current, corresponding to 100%
current setting in the PractiSPIN™.spmd software, adjusting RV1 (VREFA) and
RV2 (VREFB) trimmers on the target board. The relationship voltage/current is
V = 0.165 I
