MTS Automation MPA-03/06/09 Volt Amplifiers Simple Type: Volt Amplifier

The MPA-03/06/09 amplifier is high performance, reliable, and efficient. The amplifier is designed to be used with high performance brushless servo motors. Extreme care has been taken to assure robust operation. Design consideration for electrical transients have been implemented on the ac inputs and all I/O lines. The amplifier operates over an ac voltage range of 80 to 260 Vac from 45 to 65 Hz. The motor feedback device is a resolver to assure normal operation at elevated motor temperatures of 115° C for the case, and 155° C for the motor windings. The resolver allows for both position and velocity feedback. The motor is further protected by a thermal shutdown thermostat in the motor windings. The amplifier power switching devices are state of the art IGBT modules. The logic supply is a switch mode design reducing undesired heat. LED indicators for diagnostics are provided. Encoder simulated TTL compatible differential quadrature outputs plus an index output are provided for external pulse or position control. The amplifier has inrush current protection to allow for normal turn on. This is especially worthwhile for multiple axis. Consideration for dissipation of regenerative energy is included with internal shunt regulators.
