12.3 Optional external EMC filters
EMC filters can be sourced directly from Schaffner and Epcos. See
Table 12-33 for details.
Table 12-33 Quantum MP and EMC filter cross reference
* This filter is required if the input current to the Quantum MP will be
greater than 66Amps.
12.3.1 Typical short-term overload limits
The maximum percentage overload limit changes depending on the
selected motor
Variations in motor rated current will result in changes in the maximum
possible overload as detailed in the Advanced User Guide.
Figure 12-1 can be used to determine the maximum overload duration
available for overloads between 100% and 150%. For example the
maximum overload available for a period of 60 seconds is 124%.
Figure 12-1 Maximum overload duration available
Overload of 150% for 30s is available with ambient temperature of 40ï‚° C up to a maximum of 10 repetitions per hour.
It is essential that line rectors be connected between the filter
terminals and the power input terminals. Failure to observe
this requirement could result in destruction of the thyristors.
