P25
First fixed frequency (Hz)
00.0 –
400
(00.0)
Fixed frequency.
P26
Second fixed frequency (Hz)
00.0 –
400
(00.0)
Fixed frequency.
P27
Third fixed frequency (Hz)
00.0 –
400
(00.0)
Fixed frequency.
P28
Fourth fixed frequency (Hz)
00.0 –
400
(00.0)
Fixed frequency.
P29
Skip frequency (Hz)
00.0 –
400
(00.0)
This parameter allows a skip frequency to be selected. Operation of the
inverter will be inhibited over the range (skip frequency – 2 Hz) to (skip
fre 2 Hz). If a frequency in this range is selected, the lower or
higher frequency will be selected and displayed. Note that during
ramping the frequency output will ramp continuously and not ‘step’
through the skip range.
P30
Tachometer mode

004
(000)
This parameter enables the tachometer input and selects the
tachometer calculation rate. See section 6 for further details of
tachometer applications.
Tachometer input disabled.
Normal feedback.
Feedback control suspended during ramping.
As 001, except output disabled when frequency falls to P07 (minimum
frequency).
As 002, except output disabled when frequency falls to P07 (minimum
frequency).
