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.
Vibrational velocity V
DIN ISO 10816
Deviating from the specified standard, motors 1FK702⃞ to 1FK710⃞ 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.
