Product Description:

The MSK076C-0300-NN-M1-UG0-NNNN from Bosch Rexroth is a high-performance synchronous servo motor. It is best for tasks related to industrial automation. Known for precision and efficiency, it has natural convection cooling and a multiturn absolute Hiperface optical encoder with 128 increments. This enables accurate position feedback. The motor also has a rotatable plug connector that turns 240 levels, which allows flexibility in connection and setup. With its IP65 protection score, it is built to face challenging conditions while maintaining high reliability and constant output.

The MSK076C-0300-NN-M1-UG0-NNNN servo motor operates with a non-stop torque of 12 Nm at 60K overtemperature and 13.5 Nm at 100K. It has continuous currents of 7.2 A and 8.1 A, respectively. It can accomplish a maximum torque of 43.5 Nm and a peak cutting edge of 32.4 A. This performance is supported via a winding resistance of 1.85 Ohms at 20 degrees C and a torque consistent of 1.84 Nm/A. Additional specifications include a voltage steady of 113 V/min and a winding inductance of 12.6 mH. With four pole pairs, the motor can have a pace of 4,700 rpm which makes it suitable for instant-paced and particular obligations. The MSK076C-0300-NN-M1-UG0-NNNN servo motor has a moment of inertia of 0.0043 kgxm^2 (with brake) and a thermal time of 60 minutes. This contributes to its smooth movements and power efficiency.

Operating inside a temperature variety of 0 degrees C to 40 degrees C, the MSK076C-0300-NN-M1-UG0-NNNN have sound pressure level below 75 dB(A). This preserves operational noise to a minimum. Weighing approximately 13.8 kg, it can be integrated into automation setups without significantly impacting structural load. Its leakage capacitance is 6.5 nH which includes the motor's stability during prolonged use. This motor is engineered for applications requiring precision, endurance, and ease of maintenance.

Fault / Drive Error

Meaning (Likely Cause)

Corrective Action

Drive not-ready (“bb” on H1)

+24 V *RF* enable or 3-φ mains absent

Restore control voltage & mains fuses, then issue a Class-1 reset 

F207  Operating-mode not initialised

One of S-0-0032…35 = 0

Reload valid mode parameters; acknowledge with S1 or software reset

F208  Motor-type change detected

Drive dataset ≠ motor ID tag

Upload the correct **MSK076C-0300** file, run *Basic-Load*, power-cycle drive

F212  Encoder signals out of range

Sin/cosine amplitude too low / noisy (shield, cable or encoder)

Reseat feedback plug, route ≥100 mm from power leads, replace encoder if needed

F218  Drive heat-sink over-temperature

Cabinet airflow blocked or fan failed

Clean filters, verify fan, improve ventilation; cool drive before reset

F219  Motor over-temperature

Thermistor > ≈155 °C (over-load or poor cooling)

Reduce duty cycle, allow motor to cool, inspect temperature wiring

F220  Bleeder-resistor over-temperature

Regenerative energy above resistor rating

Lengthen decel ramp or fit / up-rate external brake resistor

F226  DC-link undervoltage (drive enabled)

Mains sag or aged DC-bus capacitors

Check 3-φ supply, supply module, replace weak capacitors

F228  Excessive control deviation

Command ≠ feedback (axis jam / poor tuning)

Free mechanics, lower acceleration, retune loops, re-reference axis

F229  Encoder-1 quadrant error

Phase sequence or noise on encoder signals

Inspect/replace feedback cable, improve shielding & grounding

F230  Max. encoder-1 signal frequency exceeded

Axis velocity above encoder interface limit

Check gearing & speed limits; fit higher-speed encoder if required
