Submenu preset frequencies
TAB1
The parameters of this submenu are used to set the three preset speeds. The sign of
the parameter value defines the rotating sense of the motor (+ forward; - reverse).
In order to permit control of the direction of rotation of the preset frequencies via termi-
nal 15, it is necessary to deactivate the sign + or − by simultaneously pressing the
keys INC and DEC after setting the desired value.
Refer to the following table for proper selection of preset frequencies.
Function A: Preset-speed FFIX1 (Default: +5 Hz)
Function B: Preset-speed FFIX2 (Default: +10 Hz)
Function C: Preset-speed FFIX3 (Default: +20 Hz)

Submenu skip frequencies
TAB1
The parameters of this submenu are used to set up to four different skip frequency
bands. A skip band is set by programming an upper and a lower limit for this band.
Skip bands may be programmed to avoid certain mechanical resonances in the drive
system. If upper and lower limits for a Skip band are equal, this band will be deactiva-
ted.
The setting is done programming a lower and an upper limit for each frequency range.
Function a: Skip-band 1 lower limit
Function A: Skip-band 1 upper limit
Function b: Skip-band 2 lower limit
Function B: Skip-band 2 upper limit
Function c: Skip-band 3 lower limit
Function C: Skip-band 3 upper limit
Function d: Skip-band 4 lower limit
Function D: Skip-band 4 upper limit
Range:
