The new X20SM1436-1 module from B&R is a new X20 module for direct control of stepper motors. The module runs stepper motors with operating voltages from 18 to 60 Vdc at currents to 2.5 A. Plus integrated current reduction function increases performance and reduces energy consumption.

With the current reduction function, B&R has integrated sensorless load-dependent current control, which significantly increases the performance of the module. By regulating the current downwards de-pending on the operating situation and load, the module allows energy savings of up to 75%.

Smoother operation: The current reduction function also significantly reduces power dissipation and heat accumulation in the module. At the same time, current control also results in the stepper motor running more smoothly. For self-protection, the stepper motor module has an inrush current limiter and a motor outlet with short circuit and overload protection.

Digital inputs with open circuit monitoring: The module has four digital 24 Vdc inputs. Three of them can be configured as ABR encoder inputs with a counter frequency of 50 kHz for 4x evaluation. In addition, all digital inputs have open circuit monitoring, which increases operational security. To detect slippage, the module has been equipped with stall detection.

The new stepper motor module from the X20 series offers sensorless and load-dependent current control.
