NOTE: Analog solutions are only applicable to larger machines tools as the cost of engineering/integration is high. This is not intended for Bed/Knee mill applications, nor is it DIY.

Put a NEW Siemens control on your machine for a fraction of the cost, reusing your motors and drives.

This Siemens 828D Control-Only Retrofit Kit is for CNC Milling Machines up to 4 interpolating axes. The following requirements must be met in order to be eligible for an analog control only upgrade: Current Drive command is analog, Drives operational, Enclosure depth from back-plate at least 12", Feedback encoders AqBq TTL, and ratios/pitches required between motors and load. This kit will allow for the eventual upgrade to a full High Performance digital drive/motor system.

For more information please see our 828 Analog Retrofit Brochure.
