Product Description:

MKD112B-024-KP0-BN is a servo motor designed and produced by Bosch Rexroth. Servo motors are equipped with sensors for measuring speed, position and torque. The MKD series comes with integrated resolver feedback. An additional encoder can be included for absolute position detection. The MKD112B-024-KP0-BN motor is equipped with the additional encoder. Operators can order plain shafts or shafts with key for MKD motors. The main shaft on the MKD112B-024-KP0-BN motor includes a key as well as a shaft seal. Convection cooling is available for out of the box operation. Surface cooling requires installation of an optional blower on the motor. Despite the higher cost, surface cooling provides improved heat dissipation, which allows motor operation with higher output current and torque. Four radial and axial blowers are available for MKD112B motors.

The blowers are available in 115 and 230 Volts AC versions. They provide between 340 and 390 cubic meters per hour airflow. The blower noise level varies between 48 and 52 dB(A). Speed rating of the MKD112B-024-KP0-BN motor is 3500 RPM and the maximum speed is 4000 RPM. Rated output torque of the motor is 31 Nm with surface cooling and 8.8 Nm with convection cooling. The rated current is 17.2 Amps with surface cooling and 4.9 Amps with convection cooling. Mass of the motor is 34 kilograms. The motor comes in an IP65. rated housing. This housing allows motor operation in a wide range of operating environments. A brushless design and use of lifetime lubricated bearings enables maintenance-free operation. Bosch recommends 0 to 40 degrees Celsius ambient temperature. The maximum setup height should not exceed 1000 meters. Only trained professionals should install and operate MKD motors.

Fault/Error What it Means Corrective Action
Motor Overtemperature (F219) Stator temperature exceeded 155 °C; drive executed emergency shutdown Check cooling air paths, fans, & heatsink; reduce mechanical load; allow motor to cool before restart
Motor Encoder Quadrant Error (F229) Corrupted encoder signals detected (quadrant error) causing loss of position Inspect/replace encoder cable; reroute or shield from EMI; replace encoder or feedback interface if needed
Motor-temperature Sensor Defective (F221) Break or short in KTY/PTC sensor wiring prevents reliable temperature monitoring Check wiring continuity; repair or replace sensor leads; replace sensor element if faulty
Undervoltage in Power Section (F226) DC-bus voltage dropped below safe threshold halting the drive Verify mains supply & fuses; inspect power wiring; correct supply issues or replace failing supply unit
Excessive Deviation (F228) Commanded vs. actual position difference exceeded allowable window Check mechanics for binding; verify motion parameters; retune position loop & test again
Excessive Position-feedback Difference (F236) Encoder channels disagree or feedback deviates from model/command Realign or replace encoder; check feedback wiring; replace feedback board if errors persist
Overcurrent (F860) Short in power stage caused current to exceed peak rating Inspect motor-power cables for shorts; test IGBTs; correct parameter limits; replace drive module if damaged
Overvoltage Warning (E825) DC-bus voltage approaching overvoltage limit due to regeneration or mains spikes Monitor mains quality; add braking resistor/regen unit; verify grounding & wiring
Uninitialized Operating Mode (F207) Controller switched into a mode that was not fully configured Complete parameter setup; re-commission drive; save settings and perform controlled restart
Travel-limit Value Exceeded (F630) Axis moved beyond software or hardware travel limits Inspect limit switch wiring; adjust soft limits; re-home axis and verify motion profile
