3.3 Vibration response
The vibration response of build-in motors in operation essentially depends on the
machine design and the application itself.
As a result of an unfavorable machine design, configuration or system settings,
resonance points can be excited, so that vibration severity level A according to
EN 6003414 is not reached.
Excessive vibration caused by resonance effects can frequently be avoided by making
suitable settings. Contact Application & Mechatronic Support Direct Motors if you
require help in applying remedial measures. You can find contact data in the Introduction
under "Technical Support".
3.4 Noise emission
WARNING
Hearing damage
Hearing damage may occur if the motor exceeds a sound pressure level of 70 dB (A)
due to the type of mounting or pulse frequency.
• Reduce the sound pressure level by implementing sound damping and/or
soundproofing measures.
The following components and settings influence the noise levels reached when built-in
motors are operational:
• Machine design
• Encoder system
• Bearing
• Controller settings
• Pulse frequency
As a result of unfavorable machine designs, configuration or system settings, measuring
surface sound pressure levels of over 70dB (A) can occur. Contact Application &
Mechatronic Support Direct Motors if you require help in applying remedial measures.
