Internal Amplifier and Drive Options

The DMC-40x0, DMC-41x3, and DMC-500x0 can be optionally equipped with a multi-axis internal servo or stepper motor drive that resides inside the metal enclosure. Controllers with 5 - 8 axes can mix and match two of the following drives. Complete documentation of the amplifiers that are listed below can be found in the appendix of the DMC-40x0 user manual, DMC-41x3 user manual, and DMC-500x0 user manual.

Drives are only available as part of a DMC-40x0, DMC-41x3, or DMC-500x0. Please see the DMC-40x0, DMC-41x3 or DMC-500x0 Part Number Generator for more information.
