12 to 48 VDC, plus a logical supply rated 5 VDC. The PractiSPIN™.spmd system is designed to operate the target module under the control of the PractiSPIN™.spmd software. Figure 1. The PractiSPIN™.spmd system block diagram AM04219v1 October 2009 Doc ID 15599 Rev 2 1/15 www.st.com...
System overview UM0696 System overview The purpose of this document is to illustrate the operation of the complete system made up by a module specific demonstration board (target board), the control board PractiSPIN™, the SW PractiSPIN™.spmd and a stepper motor. For details concerning PractiSPIN™, STEVAL-SPMD250V1, STEVAL-SPMD250V2, STEVAL-SPMD150V1 and STEVAL- SPMD150V2, please refer to the specific application notes.
UM0696 Starting PractiSPIN™.spmd Starting PractiSPIN™.spmd Since the PractiSPIN™.spmd system is capable of supporting several module demonstration boards the user must first select the module that is evaluated. ● Module demonstration board set up: configure the jumpers/switches on the target board and the control board as described in the paragraph for the specific demonstration board being used.
Starting PractiSPIN™.spmd UM0696 Figure 3. Calibration window AM04221v1 ● To null out the offset, click on calibrate zero (for details please refer to the specific target board section). ● To set the maximum current click on calibrate max (for details please refer to the specific target board section).
UM0696 Stepper motor driver Stepper motor driver After the system has established the connection to the control board, it initializes the settings to the last stored settings and open the PractiSPIN™.spmd GUI. For the stepper motor, the system can operate in either a constant speed or positioning (indexing) mode. The constant speed mode can easily be used to see that the system is working.

Stepper motor driver UM0696 ● Running speed: set running speed to about 100 steps/sec ● Deceleration rate: set deceleration rate to about 1000 steps/sec ● Acceleration current: set acceleration current to about 25%. This is an initial guess as to the required setting and may need further adjustment. Generally higher acceleration rate settings require higher acceleration current settings so that the stepper motor does not start to "slip poles"...
UM0696 Stepper motor driver Indexing mode Figure 5. PractiSPIN™.spmd indexing mode window AM04223v1 The system can be switched to operate in the positioning (indexing) mode by clicking on "switch to indexing mode". In the indexing mode a new box appears on the right of the screen.
