The minimum resonance frequency given should be interpreted as the frequency of the robot
mass/inertia, robot assumed stiff, when a foundation translational/torsional elasticity is added, i.e.,
the stiffness of the pedestal where the robot is mounted. The minimum resonance frequency should
not be interpreted as the resonance frequency of the building, floor etc. For example, if the equivalent
mass of the floor is very high, it will not affect robot movement, even if the frequency is well below
the stated frequency. The robot should be mounted as rigid as possibly to the floor.
Disturbances from other machinery will affect the robot and the tool accuracy. The robot has
resonance frequencies in the region 10 – 20 Hz and disturbances in this region will be amplified,
although somewhat damped by the servo control. This might be a problem, depending on the
requirements from the applications. If this is a problem, the robot needs to be isolated from the
environment.
At low environmental temperature < 10ºC is, as with any other machine, a warm-up phase
recommended to be run with the robot. Otherwise there is a risk that the robot stops or run with
lower performance due to temperature dependent oil and grease viscosity.
According to IEC 60529.
The protection class of the ballscrew area is IP20. For more information, please contact ABB.
