Product Description:

The DKC11.3-040-7-FW servo drive controller is part of the DKC series and designed for precision control in various demanding industrial environments. It operates on a three-phase AC input voltage between 380 and 480 V and supports a DC bus voltage range of 152 degrees CE" 420 V. With a rated current of 40 A and a peak current also at 40 A, this drive ensures robust power delivery for applications such as CNC machines, robotics, and printing presses. This DKC device features firmware version 7 which enhances its control capabilities and functionality. The firmware must be ordered separately as it is not the part of the product. It also offers a soft-start resistor of 4.7 ohms aiding in smooth start-up operations while minimizing energy surges. The operation and installation of the model must be performed by a highly trained technician in order to get maximum performance. The DKC11.3-040-7-FW module has RS232 and Analog communication interfaces. The RS232 is a serial communication interfaces used for long-distance, reliable data exchange between drive controllers and devices in industrial environments. The Analog interface transmits variable signals for precise control.

The DKC11.3-040-7-FW servo drive has a compact design with high power density that allows for installation in tight spaces without compromising on performance. The model has an operating temperature range of 0 to 40 degrees C and it is rated for an altitude of up to 1000 meters. The device is protected by an IP20 enclosure that ensures safe operation in moderate industrial environments. The DKC series servo drive supports multiple communication interfaces and can be customized with add-on cards for compatibility with different motors including MKD motors used in both single and multi-axis systems.
