The Indramat DKR drive is specifically designed for high power, high stiffness applications such as printing, packaging, and textile operations. Essentially, the DKR drives were an outgrowth and an upgrade of the classic Indramat RAC drive. Bosch-Rexroth updated this family of drives and controllers, using HMV-R as the new name.
Now these are in the IndraDrive family, the new Rexroth drives which honor — in their name — the Indramat legacy. Rexroth acquired Indramat at the end of the 20th century.
DKR drives can handle motor resolutions of up to 1/4,000,000 of a rev. They work with a number of different interfaces and loop control may be internal or external. As with most Indramat drives, the power supply module for the DKR can supply a variety of drives with different power requirements. Several different motors can be used, but parameters and cables will need to be chosen according to the motor used.
If you have a DKR drive in your facility, you might be ready to consider reman even if you don’t need factory repair. With reman, all wearing parts are required and you receive a new warranty for your like-new part.
Making this decision can keep your old gear running for some time, reducing costs and avoiding downtime.
