Product Description

DKCXX.3-100-7-FW is an EcoSeries drive controller. It is designed by Bosch Rexroth. The controller’s rated current output is 100 Amps. The DC bus voltage range is 600 to 800 Volts AC. Nominal value of the DC bus voltage is 700 Volts DC. A firmware specifying the functions of the drive must be ordered separately. The firmware integral to the drive controller determines the functional features. The firmware has its own order number. This means that it is always possible to order the identical firmware version. The firmware is continuously updated to eliminate any possible errors without altering the functionality. It is identified in the type code as the firmware release version. If newer functions are added, then the index of the firmware version is incremented. A firmware type plate is attached to the unit and allows identification of the installed firmware version.

The RS-485 interface is needed for programming, parameterizing and diagnosis during startup operation and service. The RS-485 interface allows the implementation of a serial bus with up to 31 stations, connected by means of a two-wire cable (half duplex mode). RS-485 supports a transmission length of up to 500 meters, data rates of 9600/19200 baud and the implementation of a central PC-based visualization unit. It is possible to connect EcoSeries drives directly to earthed three-phase systems with 380 to 480 Volts AC with ±10% acceptable tolerance. Only fuse protection, a mains contactor, and normally a mains filter are required in the mains input line. If the mains voltage exceeds the permitted input voltage range, the voltage must be matched by means of an autotransformer, which, in turn, has also been designed for a specified voltage range.
