Check the gear unit fastening/base Check the coupling (if present) and adjust as necessary In case of operation with a frequency inverter, check the inverter’s parameters and match it with the motor data Check whether the vibration results from the application itself (resonance frequency) The vibration frequency implies the source (e.g. high-frequency vibrations indicate the motor or the input shaft) If necessary, carry out a vibration analysis by qualified personnel or contact NORD DRIVESYSTEMS Consult NORD DRIVESYSTEMS
