Product Description:

MSM031C-0300-NN-M0-CH0 is a MSM series servo motor from Bosch Rexroth. It is a synchronous motor: its speed is in synch with the input current frequency. The motor cools via natural convection. For rated output, the ambient temperature should be between 0 and 40 degrees Celsius. Between 40 and 55 degrees Celsius, the output derates at a rate of 2% per Kelvin. For rated output, the installation altitude should be between 0 and 1000 meters. Relative humidity during operation should be between 5 to 95% and the absolute humidity should between and 1 and 29 grams per cubic meter. The MSM031C-0300-NN-M0-CH0 has smooth shaft without seal for a non-positive shaft-hub connection without play and excellent running smoothness. Operators can use clamping sets, clamping sleeves or tensioning elements to couple the motor to the driven machine elements.

The motor is equipped with an multiturn absolute encoder with 17-bit resolution. An electrical cable is provided for the power connection. Rated power output of the MSM031C-0300-NN-M0-CH0 motor is 0.4 kilowatts. The continuous torque at standstill is 1.3 Nm and the continuous output torque is 2.6 Amps. Peak torque output of the motor is 3.8 Nm and the peak current output is 7.7 Amps. The motor has four pole pairs. Its maximum speed is 5000 RPM. Weight of the motor, which does not feature a holding brake, is 1.2 kilograms. The storage temperature range for MSM motors is -20 to 60 degrees Celsius. The transport temperature range for MSM motors is -20 to 80 degrees Celsius. Icing and condensation are not permitted during storage or transportation. Protection rating of the motor is IP54. Only trained personnel should work on the motor.

Fault / Error Code meaning (common cause) Corrective action
Drive not-ready, H1 shows “bb” not “Ab” +24 V “Drive-Enable” signal or 1-φ 230 V mains missing The drive only reports bb (ready-for-power-up) until RF is high and DC-bus present; restore 24 V and mains fuses, then issue a Class-1 reset
F207 Switching to an un-initialised operating mode (one of S-0-0032…35 = 0) Reload a valid mode set, acknowledge with S1 or a software reset
F208 Motor-type change detected – drive data set ≠ motor ID tag Upload the correct **MSM031C** parameter file, power-cycle the drive
F212 Encoder signals out of range – amplitude too low / noisy Check shield & plugs, reseat M17 connector, replace encoder if faulty 
F218 Amplifier heat-sink over-temperature – cabinet airflow blocked Clean filters, verify fan, add auxiliary ventilation if required
F219 Motor over-temperature – internal thermistor > 155 °C Reduce load, allow cooldown, improve ambient airflow
F220 Bleeder-resistor over-temperature – regen overload Lengthen decel ramp or fit a higher-rated resistor module
F226 DC-link undervoltage while drive enabled – mains sag / weak capacitors Check AC feed, DC fuses & capacitors; tighten power wiring
F228 Excessive control deviation – axis jammed or poor tuning Free mechanics, lower acceleration, retune loops, re-reference axis
F230 Max. encoder-signal frequency exceeded – axis ran too fast Check gearing & speed parameters; fit higher-speed encoder if needed 
F234 Emergency-stop activated – +24 V removed at E-Stop input Trace safety chain, clear cause, then reset drive
