Product Description:

The MHD090B-035-NP0-UN is a permanent magnet motor brought to market by Rexroth Bosch. This particular motor is made with electronic commutation. Being a magnet motor, its special magnets allow for the motor to be designed with low inertia masses.

This magnet motor can be used in a number of applications in connection with any of the intelligent drive controllers brought to market by Rexroth Bosch. With this motor, you can provide the functionality to a number of automation systems. The unit can be useful in industries such as the machine tools industry, the paper and printing industries, the packaging industries, the handling, and automation industries and in the food industry as well.

The MHD090B-35-NP0-UN offers high operational reliability in any application for which it is used. With a brushless design, it allows for maintenance-free operation. Along with that, it features bearings that have been pre-greased and will last for the full-service life of the magnet motor.  The motor is designed to a number of top quality specifications that make it a great choice. It is designed to work under adverse environmental conditions if necessary. The motor features temperature monitoring to protect from overload as well as heat dissipation that ensures that the motor, in fact, has a high overload capability.

On top of being a top quality motor in build, design, and technology the motor is easy to attach and can be installed in any position you wish. This is thanks to DIN 42948 flange. It can be directly overhung with belt pulleys and pinons as the bearing are designed for high radial loads. Cabling is easy, with many cable sets being available in a variety of designs. This product is available from Wake Industrial with a one-year warranty period.

Drive / motor message What it means Corrective action
F218 – Heatsink over-temperature shutdown The drive’s internal heatsink exceeded its safe limit (≈ 95 °C) and switched off to prevent damage.  Let the unit cool, clear dust from fins, improve cabinet airflow, and verify the fan (if fitted).
F219 – Motor over-temperature shutdown PTC/NTC sensor in the motor signalled > 155 °C.  Reduce mechanical load, check ambient ≤ 40 °C, inspect cooling path or external blower.
F220 – Bleeder/regen resistor overload Dynamic-braking resistor became too hot. Lengthen deceleration ramps, install larger or forced-air resistor, verify wiring.
F221 – Motor-temperature surveillance defective Temperature sensor open/short or monitor circuit fault. Test PTC leads, repair cable, replace sensor if resistance is out of range.
F226 – DC-bus undervoltage Link voltage fell below minimum; drive shut down.  Check mains fuses and wiring, measure incoming VAC, inspect power-supply module.
F230 – Encoder 1 max-frequency exceeded Resolver/encoder frequency above interface limit (usually due to overspeed or noise). Verify speed parameters, check for runaway axis, replace damaged feedback cable.
F234 – Emergency-stop activated +24 V control dropped at the E-Stop input. Inspect E-Stop chain, reset safety relay, restore control-voltage feed.
F236 – Excessive position-feedback difference Two encoder values disagree beyond window S-0-0391.  Realign external encoder, correct resolution parameters, check mechanical backlash.
F242 – Encoder 2 signal too small Optional external encoder sine/cosine amplitude < 1 V.  Replace or re-route cable, improve shielding, confirm encoder supply voltage.
F401 – Double MST error shutdown Drive missed two SERCOS master-sync telegrams and halted.  Clean/replace fibre-optic leads, reduce loop length/attenuation, reseat SERCOS plugs.
