422969 (MAXON MOTOR)

The 422969 is a small-sized powerful 4-quadrant PWM Servo Controller for the highly efficient control of permanent magnet activated DC motors. The featured operating modes - speed control (closed loop), speed control (open loop) and current control - meet the highest requirements. The ESCON servo controller is designed being commanded by an analogue set value and features extensive analogue and digital I/O functionality and are being configured via USB interface using the graphical user interface «ESCON Studio» for Windows PCs. The servo controller has protective circuits against overcurrent, excess temperature, under- and overvoltage, against voltage transients and against short-circuits in the motor cable. Furthermore it is equipped with protected digital inputs and outputs and an adjustable current limitation for protecting the motor and the load. The motor current and the actual speed of the motor shaft can be monitored by means of the analogue output voltage.
