Product Description:
The DKC11.3-100-7-NW drive controller is manufactured by Bosch Rexroth Indramat within the DKC Drive Controllers series. It serves as a digital servo amplifier that manages torque, speed, and position loops for Indramat synchronous and asynchronous motors used in material-handling cells, packaging lines, and CNC stations. The controller works as the power and regulation stage between the supply section and the connected motor, allowing commanded motion profiles to be followed with closed-loop control. By converting rectified mains power into a regulated DC bus and exchanging data with a motion-control PLC, the unit coordinates axis movement and braking energy flow in multi-axis industrial automation.
This controller operates from a shared DC link that is held at a nominal potential of 700 V, allowing regenerated energy from braking axes to be reused across the system. During continuous operation, it can deliver a rated motor phase current of 100 A, while the upstream supply must be sized for a peak draw of 40 A on the AC side during acceleration events. Under these load conditions, the internal heat sink and fan assembly dissipate up to 420 W of power loss, which must be considered when planning cabinet ventilation. The electronic components are intended for ambient temperatures up to 45 °C without derating, so the drive can be mounted in standard factory enclosures that stay within that limit.
The housing weighs 4.5 kg, which helps limit the load placed on swing-out mounting plates inside a control cabinet. Its internal layout corresponds to Design 3, which places the power terminals and integrated brake transistor in the arrangement used for this version. Communication with higher-level controllers is provided through Interface Option 11, which includes standardized RS-232 diagnostics alongside SERCOS command channels. The module is classified as an EcoDrive and supports energy sharing on the DC bus.
