2.6 Vibration and shock
The adjustable frequency drive has been tested according to the procedure based on the shown standards:
The adjustable frequency drive complies with requirements that exist for units mounted on the walls and floors of production premises, as well as in
panels bolted to walls or floors.
IEC/EN 60068-2-6: Vibration (sinusoidal) - 1970
IEC/EN 60068-2-64: Vibration, broad-band random
2.7 Advantages
2.7.1 Why use an adjustable frequency drive for controlling fans and pumps?
An adjustable frequency drive takes advantage of the fact that centrifugal fans and pumps follow the laws of proportionality for such fans and pumps.
For further information, see the text
The Laws of Proportionality .
2.7.2 The Clear Advantage - Energy Savings
The very clear advantage of using an adjustable frequency drive for controlling the speed of fans or pumps lies in the electricity savings.
Compared to alternative control systems and technologies, an adjustable frequency drive is the optimum energy control system for controlling fan and
pump systems.
Figure 2.1: The graph is showing fan curves (A, B and C) for
reduced fan volumes.
Figure 2.2: When using a adjustable frequency drive to re-
duce fan capacity to 60%, more than 50% energy savings
may be obtained in typical applications.
