Operation Under Vibrational Or Shock Stress Conditions; Drive Coupling - Siemens 1FT7 Configuration Manual

Information on the application of motors

7.6 Operation under vibrational or shock stress conditions

7.6 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 1FT703⃞ to 1FT710⃞ may be operated with
higher loads, with the restriction that the service life will be reduced. In this case, only
operation outside the mounted natural frequency is permissible.

Drive coupling

Function description
In order to achieve optimum drive-out characteristics, ROTEX
KTR should be used. The advantages of ROTEX
● 2 to 4x torsional stiffness of a belt-driven gearbox
● No intermeshing teeth (when compared to belt gearboxes)
● Low moment of inertia
● Good control behavior
They must be optimally harmonized with existing machine masses, the mounted mechanical
system, the machine stiffness, etc.
KTR provides assistance in the selection of the coupling, refer to http://www.ktr.com
