2.1.6 Operation under vibrational or shock stress conditions
In order to ensure problem-free operation and a long service life, the vibration values defined
in DIN ISO 10816 should not be exceeded.

Deviating from the specified standard, motors 1FK702 to 1FK710 may be operated with
higher loads, with the stipulation that the service life will be reduced. In this case, only
operation outside the mounted natural frequency is permissible.
