Maxon announced ESCON 36/2 DC 4-quadrant PWM servo controller. With desirable bandwidth for optimal motor current/torque control, this digital current controller provides drift-free dynamic speed behavior through a speed range of 1 to 150,000 rpm. It can work in various operating modes (speed controller (closed loop), speed controller (open loop), current controller). The controller is controlled by means of an analog set value which can be specified. It also features the ability to enable or disable the power stage depending on the direction of rotation, or to use speed ramps for acceleration and deceleration. The speed can be regulated via a digital incremental encoder, DC tacho or without encoder.

When the servo controller is connected to a PC, it can easily be configured with the “ESCON Studio” graphical user interface. During startup and configuration of the inputs and outputs, monitoring, data recording and diagnostics, the user has access to a large variety of functions and is assisted by user-friendly software wizards, as well as an automatic procedure for fine-tuning the controller. It comes fully equipped with everything that is needed. No additional external filters or motor chokes in need and pre-assembled cables for the startup are available as accessories.

The ESCON 36/2 DC features protective circuits against over current, excess temperature, under- and over-voltage, against voltage transients and against short-circuits in the motor cable. It also has protected digital inputs and outputs and an adjustable current limitation to protect the motor and the load. The analog output voltage can monitor the motor current and the actual speed of the motor shaft.
