INDRAMAT DKC11.3-040-7-FW EcoDrive Servo controller 40A Analog

Buy online your INDRAMAT DKC11.3-040-7-FW EcoDrive Servo controller 40A Analog reference DKC11-3-040-7-FW from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This Bosch Rexroth INDRAMAT EcoDrive axis drive from the DKC11.3 Type 3 SERCOS family provides closed-loop servo control for single-axis tasks on CNC machine tools and automated equipment. In the 40 A class and commonly paired with MKD series servo motors, it is a dependable replacement unit or spare part for maintaining legacy Indramat installations on the production floor.

The unit interfaces with a SERCOS ring for CNC communication while also supporting analog command reference and a RS232 service port for setup and diagnostics. Depending on installed firmware options, it can accept analog velocity or torque reference, step and direction signals, or internal positioning functions, giving maintenance teams flexibility when matching the controller to existing control hardware.

In retrofit and field replacement scenarios, the DKC11.3 platform is valued for stable axis regulation and straightforward commissioning. The reference DKC11.3-040-7-FW identifies the hardware generation and current class as well as the firmware option set, which must match the host control and motor family for reliable operation.

Reference: DKC11-3-040-7-FW

Manufacturer: Bosch Rexroth INDRAMAT

Product type: INDRAMAT DKC EcoDrive Servo drive

Main function: Single-axis digital AC servo controller for MKD motors with SERCOS communication and analog control capability

Applications: CNC machine tools, handling systems, packaging lines, automated assembly equipment, and general industrial motion retrofits

Key technical data: EcoDrive DKC11.3 Type 3 SERCOS Interface, 40 A class axis drive, supports analog reference and step or positioning interfaces depending on firmware, RS232 port for parameterization and diagnostics, designed for use with INDRAMAT MKD servo motors (Analog. version only)

On the shop floor this controller is typically used to restore a failed axis on machines equipped with MKD motors. It is often kept as a stocked spare for critical stations where quick swap and parameter transfer through RS232 reduce machine downtime.

For preventive maintenance or retrofit work, matching the rating and firmware to the motor and CNC interface keeps integration straightforward. Many teams source this model as a CNC replacement component to extend the service life of older equipment without changing the machine’s control strategy.

Each DKC unit can be tested on dedicated CNC simulators with compatible servo motors by skilled engineers to verify communication, enable sequence, current loop stability and basic motion before shipping. Professional packaging helps protect the electronics during transit. Warranty support is available from Cnc-shopping USA. Many stocked items ship directly from our Florida facility, and shipment for this reference is typically within 3 days depending on availability.

When a legacy drive fails unexpectedly, this model is suitable as an emergency spare part to get the axis back online quickly. Cnc-shopping USA supports sourcing of obsolete parts, and repair service or exchange service may be available to help maintain older CNC installations.

Frequently asked questions about DKC11-3-040-7-FW:

Is this DKC drive compatible with MKD motors?
Yes, the DKC11.3 platform is designed for INDRAMAT MKD servo motors. Match the motor feedback and the drive’s firmware option to ensure proper operation and parameter sets.

What communication interfaces are supported?
This type 3 unit supports the SERCOS fiber-optic interface for CNC communication (Interface control PCB needs to be installed on front Slot). It also accepts analog command reference and provides an RS232 service port for commissioning and diagnostics.

What does the 40 A rating indicate?
It identifies the current class of the axis module. Select the same rating as the original unit to maintain proper current capability for the connected servo motor and application load.

Can it accept step and direction signals?
Depending on installed firmware and option configuration, the drive can operate with step and direction inputs or internal positioning functions. Verify the option set to match your control signals.

What should be checked when replacing a DKC failed unit?
Confirm the exact reference including firmware code, match the motor family and feedback type, and ensure SERCOS or analog signaling aligns with the machine’s control. Transfer parameters via RS232 as required by your maintenance procedure.
