The MHD112A-024-PP1-BN synchronous motor is one such high performance product designed for industrial applications.

The MHD112 series synchronous motor features a characteristic motor speed of 2000 rpm and a rated speed of 2500 rpm. The motor delivers continuous torque ranging from 15.0 Nm to 22.5 Nm depending on the cooling method with a peak current capacity of 59.0 A. Its voltage constant is rated at 116.4 V/1000 rpm and the winding resistance at 20 degrees C is 1.45 Ohm. It includes a torque constant of 1.28 Nm/A which contributes to high operational precision and has four pole pairs. The rated torque varies between 10.1 Nm and 19.4 Nm and the rated current ranges from 6.2 A to 12.4 A across different cooling methods. The motor can generate rated power from 3.2 kW to 6.4 kW with rated voltage options between 314 V and 355 V. The motor operates at a rated frequency of 167 Hz and has an output shaft with keyways.

The MHD112A-024-PP1-BN synchronous motor has a moment of inertia of 110 x 10^-4 kgm^2 and a maximum speed of 4000 rpm. Its insulation is class F that offers high thermal endurance and it has an IP65 degree of protection. This ensures resistance to dust and low pressure water jets. The motor mass is 23 kg and it can operate within a permissible ambient temperature range of 0 degrees C to 40 degrees C. It is equipped with a holding brake that provides a holding torque of 22 Nm operates at a rated voltage of DC 24 V and weighs 1.1 kg.

Fault / Error What it means Corrective action
F218 – Heatsink over-temperature Drive heat-sink has exceeded safe limit Lower cabinet temperature, clean or unblock airflow, replace defective blower
F219 – Motor over-temperature Internal motor thermistor > 155 °C Reduce load, verify motor cooling, check temperature-sensor wiring
F220 – Bleeder-resistor overload Regenerated energy > bleeder capacity Reduce deceleration, add external brake resistor, inspect wiring
F221 – Motor-temperature surveillance defective Open or short in temp-sensor circuit Inspect MT+ / MT– leads, repair breaks or shorts
F226 – DC-bus undervoltage Supply or regenerative energy too low Check mains, inspect DC-bus links, look for short brown-outs or blown fuses
F228 – Position-feedback difference Δ between dual encoders too large Re-reference axis, replace faulty encoder or cabling, verify grounding
F230 – Encoder-1 frequency too high Speed command exceeded encoder limit Verify velocity command, inspect gear ratio/parameter set-up
F242 – External encoder signals too small Encoder 2 failure (low amplitude) Check encoder cable & connector, swap spare cable, replace encoder if needed
F207 – Un-initialised operating mode selected Mode word points to mode “0” Write correct mode into S-0-0032…35, then power-cycle / reset drive
F401 – Double-MST shutdown Two drives detected as master on SERCOS ring Isolate duplicate master, correct SERCOS IDs and fiber routing, reset ring
