4-54. Periodic Frequency Changes
The Periodic Frequency Changes Flicker function, see Figure 4-33, provides a fixed
pattern of changes every 4 seconds. Frequency is stepped ±0.25 Hz either side of the
fundamental frequency while voltage steps by up to 1.2 V depending on voltage and
fundamental frequency settings. It should be noted that in a multiphase system the ±0.25
Hz frequency changes will occur on every phase. The voltage changes will occur only on
the selected voltage channel. See Table 4-3.
