Indramat's DKR digital drives provide the optimum solution for high power applications. The DKR offers all the advantages of digital drive intelligence and the SERCOS™ Interface fiber optic communication. DKR drives connect directly to power lines and include an integral power supply capable of full line regeneration. A wide range of motors permits optimal matching of motor to application, with variation in types of construction, performance, cooling. The following motor feedbacks are supported: Heidenhain/Stegman HSF, sine signal 1V, incremental square-wave, ENDAT, gear wheel Leonard & Bauer. Below are a few features:

	4 different models with different current ratings.
	Direct connection to 380-480V without a transformer.
	Internal Main contactor, fully line regenerative.
	Extensive Diagnostics.
	Configurable Interfaces: SERCOS, +/- 10V Analog.
	Multiple operating modes: torque, velocity, position, phase, speed ratio, cam, and coordinated.
	2 programmable analog outputs.
	Programmable response to internal drive faults.
	Drives induction and brushless servo motors.
	Many optional interface cards: I/O, analog inputs, fieldbus, master encoder, position feedback.

REFudrive offers a complete line of variable frequency inverters stand alone or modular units sharing one common power supply. All REFudrives are parameterized in the same way, so functions, interfaces, handling and options are identical for all range of products. The REFudrive has a removable operator panel that can be used to program a drive, then using a copy function in the removable operator panel, selected parameters can rapidly be transferred to additional drives without a laptop. Also the drive offers a peer-peer coupling with fiber optic cable for a super-fast direct connection between drives. Below are some features at a glance:
