Universal motor controller

The DAC1005 axis controller is a universal motor controller for one axis. DC-, two- or three-phase stepper, servo and linear motors can be connected. Powerful algorithms and high sampling rates guarantee high quality control. The interfaces for limit switches, digital and analog inputs and outputs, and encoders are integrated. The DAC1005 axis controller has two industrial-standard communication interfaces: the CAN interface and the EIA-232 (RS-232) interface.

The DAC1005 axis controller meets the CANopen standards CiA 301 and CiA 402 and has been certified by "CAN in Automation".
