The DKC21.3-040-7-FW is servo-drivecontroller manufactured by Rexroth Indramat. Designed with great compatibility for most MKD type servo motors (produced by the same manufacturer), this servo drive is built with high quality materials, optimized for excellent performance in controlling single-axis and multi-axis rotary or translational motion, and exceedingly reliable.
Typically featuring within the ECODRIVE03 drive system, the DKC21.3-040-7-FW is defined by its type-code. ‘DKC’ indicates its product type as a drive controller, and the ’21.3’ specifies its product series and version (series 21 and version 3). This drive has a type-current of 40A, as designated by the ‘040’ code, and it has a voltage category of ‘7’. Based on the series type, this drive comes with the RS232 / RS485* for inter-connectivity. Also, it features an analog interface and the ‘parallel interface 2’. Incorporating actual position detection for improving precision in servo motor control, this drive is well-suited for driving high accuracy automation operations. Depending on the intended application of the entire ECODRIVE, this servo drive could be coupled with a bleeder module or a capacitance module.
These can also help to dissipate excess regenerative energy within the system. In terms of electrical specifications, this drive can be operated in either the single-phase or three-phase mains configuration. In any of the configurations, the input voltage is expected within a range of 200 – 480 VAC, and at a frequency of either 50Hz or 60Hz. It has two specific switching frequencies for specifying current delivery/generation in both continuous and maximum capacities: 4kHz or 8kHz. At default, its full current capacity is same with the type code capacity, but it can also deliver 16A or 12.5A when frequency is switched to 4kHz or 8kHz respectively. Overall, this drive is convenient to operate, efficient, and comes with an IP20 protection against tampering.
