This stepper motor module is used to control up to 4 stepper motors with a rated voltage of 24 VDC ±25% at a motor current up to 1 A (1.5 A peak).

By individually adjusting the coil currents, the motor is only operated with the current it actually needs. This simplifies selection of the available motors and prevents unnecessary heating. Because the latter reduces energy consumption and thermal load, the effects are positive on the lifespan of the complete system. Complete flexibility is achieved by using the values for holding current, boost current and continuous current, which are completely independent of each other. The current for microsteps is automatically adjusted to the configured current values.

A stall detection mechanism is integrated to analyze the motor load. The stall is recognized using a configurable threshold. This allows an overload or motor standstill to be detected precisely in many different types of applications.
