Product Description:

The DKC02.3-016-7-FW is an EcoDrive controller built by Bosch Rexroth Indramat for the DKC Drive Controllers series. As a velocity and torque regulator for synchronous and induction motors, it forms the axis interface between a motion control system and plant-level power. The unit follows series code 02 and carries design number 3, with design version 3 and interface option 02 to match standard SERCOS or analog command chains used in automated machinery.

The controller supplies a rated output of 16 A, while its continuous current at a 4 kHz switching frequency is limited to 4 A, indicating the long-term thermal capability of the power stage. Short load peaks can be handled with a 4 kHz peak current of 6 A, giving headroom for acceleration or positioning spikes. A DC-bus nominal voltage of 700 V links the drive to common supply modules, and the inverter can generate up to 800 Hz at an 8 kHz carrier to run high-speed spindles. Because an internal DC-bus dynamic brake is not present, external energy-dump circuitry must be used when regenerative deceleration is required. The controller uses an open-chassis housing, so installation in a closed panel with forced air is expected, and ambient conditions must stay within 95% relative humidity, 25 g/m³ absolute humidity, and below 1000 m installation altitude.

Start-up inrush is limited by a 240 Ohm soft-start resistor. That resistor is rated at 0.05 kW, which helps protect upstream fuses and contactors during power-up. The drive weighs 3.2 kg, which helps reduce cabinet loading when multiple axes share one supply section. Its IP20 enclosure is intended for installation inside a control cabinet rather than in an exposed mounting position. The controller is used in conveyor sections, pick-and-place gantries, and similar motion cells.

Fault / Error Code	What It Means	Corrective Action
F207	Drive switched into an un-initialized operating mode because no valid mode was selected.	Set the appropriate operating mode in parameters S-0-0032…35, then reset and re-enable the drive.
F218	Amplifier heat-sink temperature too high.	Lower cabinet ambient below 45 °C, clean or unblock airflow, check blower; replace drive if cooling cannot be restored.
F219	Motor over-temperature shutdown (≥ 155 °C).	Reduce load or duty cycle, inspect motor cooling path, verify temperature-sensor wiring, retune velocity loop if unstable.
F220	Bleeder resistor overload from excessive regenerated energy.	Cut acceleration / deceleration rates or add external brake resistor; clear fault and re-enable.
F226	DC-bus undervoltage in power section.	Check mains supply for brown-outs, verify logic that removes Drive Enable before power loss; restore supply and reset.
F228	Excessive following error – axis cannot track command.	Raise torque limit (P-0-0092) or reduce commanded acceleration; inspect mechanics for jams; retune control loops.
F229	Encoder 1 quadrature error (signal plausibility fault).	Replace or reroute encoder cable, separate from power lines; swap encoder interface if damage suspected.
F230	Encoder 1 signal frequency exceeds interface limit.	Reduce commanded speed or select encoder with lower pulses-per-rev; clear fault and restart.
F234	Emergency-Stop input dropped +24 V.	Remove E-Stop condition, restore +24 V, issue “Reset Class 1 Diagnostics” (S-0-0099) or press S1.
F236	Position feedback 1 vs 2 difference above window.	Verify encoder-2 parameters and gearing constants, inspect mechanics for backlash, replace cable or encoder if noisy.
