2nd skip frequency. This parameter helps to prevent prolonged operation w ithin an adjustable range around the regulated
frequency. This function can be used to help to prevent a speed, w hich would cause resonance, being reached. Setting the
function to 0 renders it inactive. See page 183.
JF3
[3rd Skip Frequency]
0 to 599 Hz 0 Hz
3rd skip frequency. This parameter helps to prevent prolonged operation w ithin an adjustable range around the regulated
frequency. This function can be used to help to prevent a speed, w hich would cause resonance, being reached. Setting the
function to 0 renders it inactive. See page 183.
JFH
*
[Skip.Freq.Hysteresis]
0.1 to 10 Hz 1 Hz
Parameter visible if at least one skip frequency
[Sk ip Freque ncy]
(JPF),
[Sk ip Freque ncy 2]
(JF2) or
[3rd Sk ip Freque ncy]
(JF3) is different from 0.
Skip frequency range: betw een
(JPF
–
JFH)
and
(JPF
+
JFH)
for example.
This adjustment is common to the 3 frequencies
(JPF, JF2, JF3).
