I have some 24ohm, 0.4A, 6 wire unipolar steppers. That means 9.6Volts to the motor. I'm using a PC power supply for 5V logic and 12V for motor power.
Should I leave the center leads disconnected and run the motors as bipolar (to match the block diagram)? By connecting the 12V to M+ on the linistepper and using the appropriate power resistors from the tuning page? That would be 2.5ohm power resistors. The power supply would not be connected directly to the motors.
Or how do you wire unipolar motors to use the center leads? Should I step the 12V down to 9.6V and connect that to the center leads? Leave M+ and GND on the terminal block disconnected?
Steven James Newton of MassMind replies: No. The dotted red wire in the block diagram is used for the Linistepper and SLAm stepper. It is not used only with the THB6064AH drive. For the Linistepper, follow the diagram, including the dotted red wire.+
