FAQ

Question?

What is the significance of the "-FW" suffix on the model number DKC01.1-040-7-FW?

The "-FW" indicates that the drive's personality and functionality are determined by a separate firmware module. This particular unit comes with the FWA-ECODRV-ASE-01VRS-MS firmware. It is crucial to match the firmware to your application requirements or existing system.

Can this DKC series drive be used with motors from other manufacturers?

While technically possible in some scenarios with extensive parameter tuning, Rexroth DKC drives are specifically designed and optimized for use with Rexroth MHD, MKD, and MKE series servo motors. Using non-Rexroth motors is not recommended and can lead to performance issues or system instability.

My old drive failed. Is this a plug-and-play replacement?

It can be, provided the model number and firmware version match your old unit exactly. However, you will still need to load your machine-specific parameters from a backup. The drive does not store these parameters permanently after a complete power loss without a battery-backed parameter module. Always ensure you have a parameter backup before swapping drives.
