The FG2-00 parameter
allows jumping to any parameter in FG2 group
without scrolling to it. Press [ENTER] key and
input desired parameter code by using [SHIFT] and
[UP]/[DOWN] keys.
When [ENTER] key is pressed again, the desired
parameter will be on the display.
)* A*0+ & ' ! ' "
The VFD fault history saves information for up to
five last faults. FG2-01 parameter shows the latest
VFD fault. Each registered fault contains the
following information at trip moment: Frequency
(Hz), Current (A), VFD Mode (Acc, Dec, Steady or
Stop) and Run time at trip. In order to read the fault
information press
[ENTER] key and use the
[UP] /[DOWN] keys to cycle trough Hz, Amps,
VFD status, and trip time. Press [ENTER] key to
return to fault parameter.
When all faults are checked, they can be cleared by
setting FG2-06 to Yes. After all faults are erased in
the fault history, FG2-06 parameter will show No.

The following time format [
1:12:30:24:60]
is used
in the VFD. Starting from the left to the right, (1) is
the number of years, (12)- number of months, (30)-
number of days, (24)- number of hours, (60)-
number of minutes.
FG2-07 shows accrued On-Time since last
activation of fault relay.
FG2-08 shows total VFD powered up time.
FG2-09 shows total VFD run time.

When FG2-10 is set to 1~6000sec., the dwell
function is enabled. The VFD will ramp up to FG2-
11 frequency and stay at that frequency for FG2-10
time and then continue ramping up to the speed
reference frequency. This function can be used in
mixer type applications where premixing in lower
speed is required before switching to high speed.
If the SET-34 Sleep Boost Value is set greater than
0 for pump applications, the VFD uses FG2-11
frequency as Sleep Boost Frequency which VFD
will ramp up to in order to increase system pressure
before Sleep Mode is activated.

The Jump (Skip) Frequencies are used to bypass
mechanical system resonance frequencies in order
to protect system from damage by vibration. The
system can have more than one resonance
frequency. When FG2-12 is set to Yes, the Jump
Frequency parameters FG2-13~18 become
available.

The mechanical resonance frequency is actually a
small frequency range. VFD allows setting Low
and High frequencies for each resonance frequency
range up to three ranges total. The diagram below
shows settings for three resonance frequency
ranges.
