Introduction
MPA Amplifiers represent a series of amplifiers that are high performance, reliable, and
efficient. The amplifiers are 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. MPA
amplifiers operate over ac voltage ranges 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 high power switching devices are state of
the art IGBT modules. The logic supplies are switch mode designs 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 amplifiers have 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.
The ANF3 Feedback Board is available as a means of providing multiple configuration and
extended features to the MPA Servo Amplifier.
