  • Page 2 Introduction, Features and Applications WM540 Driver is a high performance microstepping driver based on the most advanced technology in the world today. It is suitable for driving 2-phase and 4-phase hybrid step motors (current 4.0A). By using advanced bipolar constant- current chopping technique, it can output more speed and power from the same motor, compared with traditional technologies such as L/R drivers.

DIP setting for current during standstill: SW4 is used for this purpose, the half current setting will reduce motor heating at standstill. OFF meaning that the standstill current is set to be half of the dynamic current and ON meaning that standstill current is set to be the same as dynamic current.
