Product Description:

Bosch Rexroth sets a true example of entrepreneurship by acting upon new initiatives with a full spirit and determination and achieved the goals. Building a trustful relationship with their investor, business partners and associates is also the key to their global success. Their working principle totally surrounds this epigram “We deliver what we promise”. With IndraDrive they operate all their products. From welding technology to tightening technology, from industrial hydraulics to mobile hydraulics their dynamic system accommodates all types of product groups. Rexroth controls all automation technology and provides a vast portfolio of services.

Rexroth equips the automation systems with capabilities that one need, in order to continue the standards for performance and innovations. The MSK071D-0300-NN-M1-UG1-NNNN has natural convection, a cooling mode having a length D and a size 071. The AC motor is grounded on a motor cable and over an unconnected ground wire with a cross-section of 4mm2. The maximum operating temperature for these rotors for motors is 115 Celsius. And are only for attachment with the machine. Environmental conditions such as humidity, ambient temperature, vibrations should be checked before installation, they should not exceed the details available in project planning manual. After switching them off, let them cool down for a long time, up to 140 minutes, before accessing them. For the prevention of unwanted motor vibration and for more precise operation, the rotor of motor sold is properly balanced by using new measuring technologies. This motor has great efficiency, with low cost and has proper functioning of encoders, resolvers and techno generators as Rexroth pay full attention in the testing of the motor measuring system. These series hold a greater load as it has the higher torque.

Fault / Drive Error Meaning (Likely Cause) Corrective Action
Drive stays “bb” (not-ready) +24 V RF enable or mains supply absent Restore 24 V at RF input, check 3-φ fuses; issue Class-1 reset 
F207 Un-initialised operating mode One of S-0-0032…35 = 0 Reload correct mode set; acknowledge with S1 or software reset 
F208 Motor-type change detected ID in encoder ≠ dataset in drive Upload MSK070D-0300 file, run *Basic-Load*, power-cycle 
F212 Encoder signals out of range Sin/cos amplitude too low or noisy Reseat feedback plug, separate from power leads ≥ 100 mm, 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 
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 above resistor rating Lengthen decel ramp or fit / up-rate external brake resistor 
F226 DC-link undervoltage Mains sag or aged DC-bus capacitors Check 3-φ supply & caps, tighten power wiring 
F228 Excessive control deviation Command ≠ feedback (axis jam / poor tuning) Free mechanics, lower accel, retune loops, re-reference axis 
F230 Max. encoder-1 signal frequency exceeded Axis velocity above encoder interface limit Review gearing & speed limits; fit higher-speed encoder if required

Frequently Asked Questions about MSK071D-0300-NN-M1-UG1-NNNN:

Q: Can the MSK071D-0300-NN-M1-UG1-NNNN operate effectively without fan unit?

A: Yes, fan units are only required when the MSK071D-0300-NN-M1-UG1-NNNN is used in high repetition rates or continuous operation. Motors with fan units are not suited for applications with continuous shock loads.

Q: Can I order the MSK071D-0300-NN-M1-UG1-NNNN with fan units?

A: The fan unit can be purchased and supplied as a sub-item to the MSK071D-0300-NN-M1-UG1-NNNN.

Q: What are the recommended operating conditions for the MSK071D-0300-NN-M1-UG1-NNNN?

A: The ambient temperature at which the MSK071D-0300-NN-M1-UG1-NNNN is operated should fall between 0 to about 400C, the maximum installation height for the motor is about 1000 meters above sea level. The motor is not suitable for underwater operation.

Q: What type of lubricant can I use with the MSK071D-0300-NN-M1-UG1-NNNN?

A: The MSK071D-0300-NN-M1-UG1-NNNN has been certified to be compatible with a wide range of lubricants, however it is still compulsory for end users to carry out a compatibility test between new lubricants and the motor to prevent damage.

Q: How often should the shaft seal of the MSK071D-0300-NN-M1-UG1-NNNN be greased?

A: Ideally, the shaft seal of the MSK071D-0300-NN-M1-UG1-NNNN is greased for its lifetime, however if the motor is used in unfavorable environmental conditions (grinding dust and metal shavings) maintenance intervals could be necessary.
