Downtime rarely waits for perfect sourcing. If your machine runs on EcoDrive DKC drive controllers, the fastest replacement is the one that is both available and correctly matched to your type code. Indramat-USA is a premier independent source for EcoDrive DKC drive controllers, supporting refurbishment-backed replacements, new surplus when available, and legacy or obsolete sourcing for installed-base equipment.
This page focuses on the three most common EcoDrive03 amp sections—040, 100, and 200—and provides a compatibility-first quote path that reduces wrong-part risk. Other EcoDrive current classes are also available across the broader DKC family, including 004, 008, 012, 016, and 018, but 040, 100, and 200 remain the most commonly requested configurations for replacement, repair, and spare-parts support.
What is EcoDrive?
EcoDrive is a cabinet-mounted servo drive platform designed to manage both motor power delivery and closed-loop axis control within a single integrated system. It combines a regulated power section, high-speed drive control electronics, feedback processing for rotor position and motion monitoring, and a diagnostic and parameter structure that determines how the axis performs in operation. Depending on the specific model and firmware configuration, EcoDrive systems support closed-loop functions such as torque control, speed control, and position control. Certain versions also support drive-based interpolation, allowing commanded target positions to be processed and executed directly within the drive.
How to match the correct DKC drive controller
Correct matching starts with the complete type code on the nameplate. The amp section (040/100/200) is critical, but it is not the entire story. Voltage category and firmware requirements can affect interchangeability. For that reason, a “close match” is often a costly mistake in legacy motion systems.
If you are unsure, requesting verification using a nameplate photo is the safest path. It allows your quote to be aligned with your exact controller family and configuration.
An example of a properly formatted DKC type code is:
Compare AMP Sections 040 vs 100 vs 200
The amp section is tied to the controller’s peak “type current” and to continuous current limits that depend on switching frequency. The table below clearly separates peak/type current from continuous current at 4 kHz and 8 kHz. Other voltage categories and current ratings exist in the broader DKC family; specifications below focus on common EcoDrive03 variants and should be verified against your exact type code.
Parameter | 040 | 100 | 200 |
Peak/type current | 40 A | 100 A | 200 A |
Continuous current @ 4 kHz | 16 A | 40 A | 100 A |
Continuous current @ 8 kHz | 12.5 A | 32 A | 68 A |
Input voltage range (common high-voltage variants; voltage category dependent) | 200–480 VAC ±10%, 1φ or 3φ | 200–480 VAC ±10%, 1φ or 3φ | 200–480 VAC ±10%, 1φ or 3φ |
DC bus voltage range (mains dependent) | 300–800 VDC | 300–800 VDC | 300–800 VDC |
Form factor (H × D × W) | 360 × 261 × 65 mm | 360 × 261 × 105 mm | 360 × 261 × 230 mm |
Weight | 5.7 kg | 9.7 kg | 19.5 kg |
Typical applications | Smaller axes, compact cabinets, lighter duty cycles | General automation “workhorse” axes, common replacements | Higher-demand axes, heavier loads, higher regen sensitivity |
Compatible motors (examples; confirm feedback + firmware) | MKD/MHD/MKE | MKD/MHD/MKE | MKD/MHD/MKE |
Common faults | F218, F226, F229, F860 | F218, F220, F226, F229, F860 | F220, F226, F229, F860 |
016 Amp Section
The 16 amp DKC class is commonly associated with the DKC**.1-040-7-FW configuration, a compact EcoDrive controller designed for cabinet-mounted servo applications that require dependable closed-loop motor control without moving into a larger current class. In this configuration, the drive uses a three-phase 380 to 480 VAC input with selectable 4 or 8 kHz switching and is supported by a 24 VDC control supply, making it well suited for legacy motion systems where footprint, electrical compatibility, and exact part-number matching all matter.
040 Amp Section
The 040-amp section is a frequent installed-base replacement in compact systems. It is typically selected where the application requires the 040 peak/type class and where cabinet space is constrained. For continuous-duty applications, switching-frequency-dependent continuous current matters; provide duty cycle details if your axis demands sustained torque.
100 Amp Section
The 100-amp section is a common “workhorse” class across many EcoDrive03 installations. It is often used where the 040 class is undersized for continuous operation or peak acceleration requirements. If your application has frequent decel events or high inertial loads, include that detail so braking and regeneration behavior can be assessed as part of the quote.
200 Amp Section
The 200-amp section is a larger physical frame and is typically encountered on higher demand axes. Because regen energy and thermal load can be more significant at higher power levels, it is common to evaluate cabinet airflow and braking strategy alongside the controller replacement.
Common Fault Code Errors and Repair Service
EcoDrive controllers use front-panel alphanumeric diagnostics to help identify the source of a shutdown or performance issue. Common downtime conditions include heatsink overtemperature shutdowns, DC bus undervoltage faults, low battery voltage alerts tied to absolute encoder feedback, and overcurrent shutdowns caused by motor cable shorts or internal power section failures.
In some cases, these issues can be corrected by restoring proper cooling airflow, improving cabinet thermal conditions, correcting wiring faults, or addressing unstable incoming power. In other cases, the fault points to a failure within the power section or feedback circuitry and calls for professional repair or replacement. Because EcoDrive systems are highly configuration-sensitive, Indramat-USA can help evaluate both repair and replacement options to reduce downtime and support a more cost-effective long-term maintenance strategy.
