Product Information
E5-CAT-ST68D is Shenzhen ECON Technology's new EtherCAT open loop stepper driver,using the latest floating-point 64-bit MCU digital processing technology,the drive control algorithm using advanced variable current technology and advanced frequency conversion technology,the driver low heat,small motor vibration,running smooth.The user can set any ID address within 1-255 and any current value within rated current, motor matching and so on,to meet most occasions application.The bus driver can drive two-phase open-loop stepper motor,three-phase open-loop stepper motor.Due to the built-in micro-step technology, the high subdivision effect can be achieved even under the condition of low subdivision. The low, medium and high speed operation is smooth and the noise is ultra-small.The driver integrates the function of parameter auto-tuning,which can automatically generate optimal operating parameters for different motors to maximize the performance of the motor
