Prevention: Use the formula provided in the manual to calculate the actual radial force, ensuring that it is less than the allowable value. For high vibration applications, consider using elastic couplings.
Problem: High oil temperature or oil leakage.
Troubleshooting: Check if the oil level is correct (either too high or too low can cause temperature rise); Check whether the environmental temperature and heat dissipation conditions comply with the heat capacity model (P_t * f_t); Confirm that the breathing valve is not blocked.
Prevention: Regularly check the oil level (the manual recommends monthly checks for intermittent work, and more frequent checks for continuous work); Ensure that there is an appropriate margin for heat capacity when selecting.
Problem: The motor frequently trips due to overload.
Troubleshooting: Check if the actual load torque of the application exceeds the design value; For the variable frequency drive scenario, it is confirmed that the torque reduction is caused by the decrease in the efficiency of the motor cooling fan when operating in the low-speed (such as 6-12Hz) constant torque zone (see tables F22 and F23 in the manual "Inverter Operation").
Prevention: During the selection phase, if it is confirmed to be a variable frequency drive, it is necessary to refer to the "Turn down" data provided in the manual, or choose a motor (IC416) with an independent cooling fan (servo fan) for low-speed applications.
