Product Description:

MSK071E-0300-NN-M1-UG1-NNNN is a MSK series servo motor from Bosch Rexroth. At delivery, MSK motors are packed in cardboard boxes or wooden crates. Retaining straps secure packing units on pallets. MSK motors undergo different electrical and mechanical tests at the factory. As MSK motors undergo standardized inspection test, high-voltage tests at the customer site are not required. Every MSK motor comes with a type listing the designation and relevant technical information. A second type plate is also delivered with each MSK motor. The type plate is provided for motor identification, spare parts procurement, and service information. Suitable lifting devices must be used when handling MSK motors. Personnel should use protective equipment and clothing to prevent injuries. MSK motors must be stored horizontally in their original packaging. The storage environment must be dust-free, dry, vibration-free and safe from direct sunlight.

MSK071E-0300-NN-M1-UG1-NNNN is a MSK servo motor with a multiturn encoder for speed and position feedback. The main shaft has a plain design. The shaft is fitted with a sealing ring for ingress protection. The motor is also equipped with a holding brake. This is a device designed to prevent motor accidental shaft rotation. The brake allows shaft rotation only after receiving an electrical release signal. Holding torque rating of the brake is 23 Nm. The voltage rating is 24 Volts DC and the current draw is 0.79 Amps. The connection time is 35 milliseconds and the disconnection time is 180 milliseconds. Power connector on the MSK071E-0300-NN-M1-UG1-NNNN motor can be rotated 240 degrees. With an IP65 rated housing, the motor can be installed in a range of operating conditions. Only trained professionals should work on the motor.

Fault / Drive Error

Meaning (Likely Cause)

Recommended Corrective Action

Drive shows “bb” (not-ready)

24 V RF (Drive-Enable) or mains still absent

The controller stays in “ready-for-power-up”; restore +24 V at RF and verify 3-φ fuses, then issue a Class-1 reset 

F207 Un-initialised operating mode

At least one S-0-0032…35 mode parameter = 0

Reload a valid mode set, acknowledge with S1 or software reset 

F208 Motor-type change detected

Drive data ≠ ID stored in encoder tag

Upload the correct **MSK071E-0300** data set, run *Basic-Load*, power-cycle drive 

F212 Encoder signals out of range

Sin/Cos amplitude too low or noisy

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, allow cool-down before reset 

F219 Motor over-temperature

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

Reduce duty cycle, let motor cool, check temp-sensor wiring 

F220 Bleeder-resistor over-temperature

Regen energy exceeds resistor rating

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

F226 DC-link undervoltage

while enabled

Mains sag or aged DC-bus capacitors

F228 Excessive control deviation

Command ≠ feedback (axis jam / poor tuning)

Free mechanics, lower acceleration, retune position loop, 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 interface limit

Check gearing & speed limits; fit higher-speed encoder if profile demands

Error Code

Brief Description

F207

Operating-mode not initialised (S-0-0032…35 = 0)

F208

Motor-type change detected – drive data ≠ motor ID

F212

Encoder signal amplitude out of range (low / noisy)

F218

Drive heat-sink over-temperature – amplifier shut down

F219

Motor over-temperature – thermistor trip > ≈ 155 °C

F220

Bleeder-resistor over-temperature – regen overload

F226

DC-link undervoltage while drive is enabled (mains sag / weak caps)

F228

Excessive following-error / control deviation

F229

Encoder-1 quadrant error (phase sequence / noise)

F230

Encoder-1 signal frequency exceeded (axis velocity too high)
