Page 3: Introduction, Features And Applications
Avoid dust, oil fog and corrosive gases Environment 0 ℃ －50 ℃ (32℉－122℉) The M752 is a high performance microstepping driver based on pure-sinusoidal current control Ambient Temperature technology. Owing to the above technology and the self-adjustment technology (self-adjust current 40%RH－90%RH... -
Page 4: Pin Assignment And Description
The M752 can accept differential and single-ended inputs (including open-collector and PNP output). reverse by inside jumper J2. The M752 has 3 optically isolated logic inputs which are located on connector P1 to accept line Enable signal: This signal is used for enabling/disabling the driver. High level driver control signals. -
Page 5: Connecting The Motor
5. Connecting the Motor motors should be run at only 70% of their rated current to prevent over heating. The M752 can drive any 2-pahse and 4-pahse hybrid stepping motors. Connections to 4-lead Motors 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding Figure 7: 6-lead motor full coil (higher torque) connections inductance. -

7. Selecting Microstep Resolution and Driver Output Current The M752 can match medium and small size stepping motors (from NEMA frame size 17 to 43) This driver uses an 8-bit DIP switch to set microstep resolution, and motor operating current, as made by Leadshine or other motor manufactures around the world. -

Theoretically, this will reduce motor heating to 36% (due to P=I *R) of the original value. If 5000 the application needs a different standstill current, please contact Leadshine. -
