The EJ7411 EtherCAT plug-in module provides high control performance in a very compact design for the medium output range of BLDC motors. Due to the fast control technology and the connection of an incremental encoder, both very high speed profiles and dynamic positioning tasks can be implemented. Maximum operational reliability is provided through the monitoring of numerous parameters, such as overvoltage, undervoltage, overcurrent, module temperature or motor load via the calculation of an I2T model.
