● Pulse frequency wobbling can only be activated under the following conditions (p1810.2 =
1):
– The drive is pulse suppressed.
– p1800 < 2 x 1000 / p0115[0]
● p1811 (Pulse frequency wobbling amplitude) can only be set under the following
conditions:
– p1802.2 = 1
– p0230 (output filter) < 3 (no sine-wave filter)
● When pulse frequency wobbling is activated and impulses are enabled, the maximum
pulse frequency (p1800) can be set as follows:
– For p1811 = 0: p1800 ≤ 2 x 1000 / p0115[0]
– For p1811 > 0: p1800 ≤ 1000 / p0115[0]
● When pulse frequency wobbling is activated and impulses are enabled, if the maximum
pulse frequency (p1800) is set to be greater than 1000 / p0115[0], then p1811 is set to 0.
● When pulse frequency wobbling is activated and impulses are suppressed, if the
maximum pulse frequency (p1800) is set to be greater than 2 x 1000 / p0115[0], then
p1811 and p1810.2 are set to 0.
