Used with 8192 encoder feedback motors on smaller linear way machines. The AMP-0040C is a digital version of the legacy AMP-0040 and is suitable as a drop in replacement. Many of the thru hole components have been replaced with surface mount components to increase product reliability. This amplifier can be used with AC axis motors with 8192 encoders. Wiring is identical to the AMP-0040. Pot location and adjustment is the same as the AMP-0040. Produces identical ball bar results as the legacy version. Can be programmed for other motors if required. Replaces AMP-0043 and AMP-0039.
