With the X20SM1436-1 module, B&R has added to its portfolio a new X20 module for direct control of stepper motors. The module can be used to operate stepper motors with operating voltages from 18 to 60 VDC at rated currents up to 2.5 A. In addition, the 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 depending on the operating situation and load, the module allows energy savings of up to 75 percent.
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
