Product Description:

The KSM01.2B-061C-35N-M1-HP0-NN-D7-NN-FW Servo Motor is engineered for precise motion control in industrial automation systems. Designed by Bosch Rexroth, this motor offers a compact design and includes a multi-turn absolute optical encoder for accurate positioning. Key features include a high-power rating of 6 kW, a SERCOS interface for communication, and natural convection cooling. This makes it suitable for systems that demand high efficiency and reliability.

The KSM01.2B-061C-35N-M1-HP0-NN-D7-NN-FW servo motor operates with an input voltage range of 540-750 V DC and can reach a maximum speed of 4300 RPM. It delivers a maximum torque of 25 Nm, with a standstill torque of 6 Nm. The motor supports a maximum current of 14.9 A and a continuous current of 3.3 A that ensures stable performance under varying load conditions. The natural convection cooling system eliminates the need for additional cooling mechanisms that reduce installation complexity. The motor's IP65 protection rating ensures it is completely dust-tight and protected against low-pressure water jets that allow it to perform reliably even in challenging conditions. With its SERCOS interface, the KSM01.2B-061C-35N-M1-HP0-NN-D7-NN-FW servo motor communicates efficiently with control systems that ensure fast and precise control in industrial automation setups. The integrated hybrid connector simplifies the wiring by combining power, control, and communication into one cable reducing installation time and minimizing potential errors.

The motor's compact design allows for easy installation in spaces with limited room. The wide operating temperature range of 0 degrees C to 40 degrees C ensures optimal performance. The KSM01.2B-061C-35N-M1-HP0-NN-D7-NN-FW motor can be stored at temperatures between -20 degrees C and +85 degrees C without damage to ensure long-term durability. Depending on the configuration, its weight ranges from 5.5 kg to 14.5 kg which makes it lightweight and easy to integrate into various automation systems. The motor can operate in environments with relative humidity levels ranging from 5% to 95%.

Fault / Error Code  Likely Meaning Recommended Troubleshooting Step
F218 Drive-integrated heat-sink temperature exceeded shut-down threshold Improve machine / cabinet airflow, clean the axial blower on the motor, allow unit to cool < 45 °C, then perform a Class-1 Reset before re-enabling.
F219 Motor winding thermistor signalled over-temperature (~155 °C) Reduce load or duty cycle, check whether the motor housing is clogged with dust/oil, verify thermistor wiring; re-enable only after the motor is cool to the touch.
F226 DC-link undervoltage detected while drive was enabled Inspect the hybrid-cable supply for loose connectors or brown-outs, make sure Drive Enable drops before mains contactor opens, restore supply and reset.
F227 DC-link over-voltage during braking (regen energy too high) Lengthen decel ramps, add or up-size an external brake resistor in the Mi chain, clear the fault when bus voltage ≤ 730 V.
F8022 Encoder-1 signal incorrect (noise, cable fault, or encoder damage) Reseat/replace the hybrid cable, keep it separated from motor-power leads, replace the encoder if the fault recurs.
F8028 Over-current in power stage (IGBT trip) Check motor phases for shorts, verify current limits & correct motor data, test IGBT module if fault repeats.
F8064 Interruption of one motor phase (open conductor) Examine the hybrid-cable crimps at both ends, megger motor windings, repair or replace the damaged conductor, then reset.
F8070 +24 V control-supply undervoltage Measure 24 V at X31 of the Mi supply, tighten terminals, up-size the PSU if the rail sags below 22.8 V under load.
F8135 Velocity threshold exceeded (trend monitoring) Investigate for mechanical jams, verify gear-ratio parameters, reduce commanded acceleration, retune velocity loop.
F2100 Invalid access to command-value or parameter memory Power-cycle the drive; if the fault returns, reload firmware/project via IndraWorks or replace the control section MMC.
