Max-400 Baldor Servo Drive

The Baldor / Reliance / Electro-Craft Max-400 Series Servo Drives are designed to drive permanent magnet, brushtype, DC servo motors. The drives and motors are intended for use in a broad range of industrial servo applications, including machine tool and robotic applications, along with torque, velocity, and position type servo systems. Each drive is a self-contained unit, ready for mechanical installation and electrical interconnections to the AC power transformer, motor-tachometer, and controller. The Rockwell / Reliance / Electro-Craft MAX-400 series is a controllable power source for brushtype, DC servo motors. Usually configured as a controlled velocity system, the drive interfaces with a controller which provides an analog voltage signal proportional to the desired motor velocity. The MAX-400 series drives can also operate in torque mode (or current mode), such that a controller provides an analog voltage signal proportional to the desired motor torque. The MAX-400 series drives contain circuitry for protection of both motor and drive from effects of various overload and short circuit conditions. The command signal to the power drive can be monitored at the ICMD output. The MAX-400 series is a pulse-width modulation (PWM), switching type drive that reduces system power losses. Motor speed is precisely controlled down to a maximum torque, low velocity condition.
