Introduction
The AMP-20542 is a four-axis PWM servo amplifier designed for direct plug-in to the DMC-
21x3 motion controller. It requires a single input DC power supply of 18-60V, is capable of
handling up to 200 W continuous per axis, and is rated at 3.3A continuous, 5A peak. The axes
are individually software configurable for brush or brushless operation, as are the axes gains of
0.1, 0.25, or 0.5 A/V.
There are two software-configurable modes of operation to suit low inductance motors. These
modes are Inverter (for motors with 500 μH or greater inductance) and Chopper (for motors
with 200-500 μH inductance), configured by the AU command. The amplifier cannot be used
with controllers other than the DMC-21x3.
