Product Description:

Bosch Rexroth is a worldwide supplier of various automation products. The company produces sustainable and affordable products for its customers.

The DKR02.1-W200N-BE32-01-FW model is developed to provide high operational reliability in various industrial sectors such as machine tools, handling systems, printing machines, and robotics. It is mainly used to control and monitor the operations of Indramat AC electrical motors. The model is equipped with an RS-232 serial interface for connecting VT-terminals or PC and the error/faults can be diagnosed via an H1 status display. The DKR02.1 drive controller is equipped with a built-in power supply module that takes electrical connection directly from the 3-phase power source and the rated current requirement for this model is 200 A. The AC 3 × 400 – 480 V of supply voltage is required to operate the drive controller. The DKR02.1 drive controller comes with a 4/8 kHz drive which operates at the power voltage of 0 – 380 V with the system frequency of 800/1600 Hz. The current requirement for the 4/8 kHz drive is 120/95 A with a continuous power delivery of 47/37 kW.

The model DKR02.1-W200N-BE32-01-FW is trusted by our customers around the globe and it is widely used to produce efficient motion control systems. The basic unit of the drive controller consists of 5 plug-in slots. U1 slot is equipped with a SERCOS interface whereas, a digital servo and resolver feedback is installed in this model. The operating software of the controller is installed into the firmware module (ESM 02.3) which can be mounted into the U5 slot of the basic unit. The controller housing comes under IP 20 protection category and it can operate ideally at the maximum altitude of 1000 m/sea level. The maximum bearable temperature for the DKR02.1 drive controller is +55 degree Celsius, with derating. Wake Industrial provides state-of-the-art industrial automation products to its clients along with a one-year replacement warranty.

Fault / Error Code What it Means Corrective Action
F2-05 Drive tried to switch into an operating mode that has not been initialized Load the correct operating mode in parameters S-0-0032…0035, save, then issue Reset Class 1 Diagnostics or cycle power.
F2-18 Heatsink temperature exceeded shutdown limit Lower cabinet ambient ≤ 45 °C, verify blower airflow, clean filters; replace fan or relocate drive if cooling cannot be restored.
F2-19 Motor thermal sensor signalled over-temperature Reduce load or duty cycle, inspect motor blower path, check temperature-sensor wiring, allow cool-down and re-enable.
F2-20 Internal brake/bleeder resistor overheated due to excess regenerated energy Extend decel ramps or add an external brake resistor; clear fault and restart.
F2-26 DC-bus undervoltage detected while drive was enabled Check mains for brown-outs, verify “Drive Enable” is removed before power loss; restore supply and reset.
F2-28 Following-error (position deviation) exceeded permissible window Reduce commanded accel/decel, verify mechanics for binding/backlash, retune velocity/position loops.
F2-29 Encoder 1 quadrant-error (signal plausibility fault) Inspect encoder cable routing, separate from power lines, replace encoder or interface card if error persists.
F2-30 Encoder 1 signal frequency above interface limit Lower maximum speed or fit encoder with fewer pulses-per-revolution; clear fault and resume.
F2-33 External +24 V control-supply missing/out of tolerance Verify 24 V supply capacity, tighten terminals, replace PSU if sag detected; reset once stable.
F2-34 Emergency-Stop chain opened (+24 V removed at E-Stop input) Investigate E-Stop circuit, restore +24 V, perform fault reset after the safety circuit is closed.
