4. Figure 8 8 lead motor series connections Parallel Connections An 8 lead motor in a parallel configuration offers a more stable but lower torque at lower speeds But because of the lower inductance there will be higher torque at higher speeds Multiply the per phase or unipolar current rating by 1 96 or the bipolar current rating by 1 4 to determine the peak output current r Pies M Figure 9 8 Lead motor parallel connections 6 Power Supply Selection The DMS03 can match medium and small size stepping motors from NEMA frame size 17 to 34 made by Leadshine or other motor manufactures around the world To achieve good driving performances it is important to select supply voltage and output current properly Generally speaking supply voltage determines the high speed performance of the motor while output current determines the output torque of the driven motor particularly at lower speed Higher supply voltage will allow higher motor speed to be achieved at the price of more noise and heating If the motion speed requirement is low it s better to use lower supply voltage to decrease noise heating and improve reliability Regulated or Unregulated Power Supply Both regulated and unregulated power supplies can be used to supply the driver However unregulated power supplies are preferred due to their ability to withstand current surge If regulated power supplies such as most switching supplies

7. Setting Notes Due to motor inductance the actual curent in the coil may be smaller than the dynamic current setting particularly under high speed condition Standstill Current Setting SWA is used for this purpose OFF meaning that the standstill current is set to be half of the selected dynamic current and ON meaning that standstill current is set to be the same as the selected dynamic current The current automatically reduced to 50 of the selected dynamic current one second after the last pulse Theoretically this will reduce motor heating to 36 due to P I R of the original value If the application needs a different standstill current please contact Leadshine Auto Tuning by SW4 The DMS03 can identify the driven stepper motor and automatically configure the current loop for optical performance Change the modes switch SW4 two times ON gt OFF gt ON or OFF gt ON OFF in one second after powering up The motor parameter will be identified and the drive s current loop parameters are calculated automatically The motor shaft will have a litle vibration during auto configuration Auto Tuning Requirement and Procedure 1 Motor is connected to drive sm s swe 2 Power is connected to drive 3 Tum on the power 4 Make sure there is no pulse applied to drive 5 Switch SW4 two times in one second That is Ot N OFF OFF ON OFF or ON OFF ON D Leadshine abet ed E A 8 Wiring Notes In order to
