Semi-Automatic Bypass Speed Set-up
The Semi-Automatic Bypass Speed Set-up can be used to facilitate the programming of the frequencies to be
skipped due to resonances in the system.
The following process is to be carried out:
1. Stop the motor.
2. Select Enabled in par.4-64
Semi-Auto Bypass Set-up.
3.
Press
Hand On
on the keypad to start the search for frequency bands causing resonances. The motor will
ramp up according to the ramp set.
4.
When sweeping through a resonance band, press
OK
on the keypad when leaving the band. The current
frequency will be stored as the first element in par.4-62
Bypass Speed to [RPM] or par.4-63 Bypass Speed
To [Hz] (array). Repeat this for each resonance band identified at the ramp-up (maximum four can be ad-
justed).
5. When maximum speed has been reached, the motor will automatically begin to ramp-down. Repeat the
above procedure when speed is leaving the resonance bands during the deceleration. The current frequen-
cies registered when pressing
OK
will be stored in par.4-60 Bypass Speed From [RPM] or par.4-61 Bypass
Speed From [Hz].
6.
When the motor has ramped down to stop, press
OK
. The par.4-64 Semi-Auto Bypass Set-up will automat-
ically reset to Off. The adjustable frequency drive will stay in
Hand
mode until
Off
or
Auto On
are pressed on
the keypad.
If the frequencies for a certain resonance band are not registered in the right order (frequency values stored in
By Pass Speed To
are higher than those in
By Pass Speed From
) or if they do not have the same numbers of
registrations for the
By Pass From
and
By Pass To
, all registrations will be canceled and the following message
is displayed:
Collected speed areas overlapping or not completely determined. Press [Cancel] to abort
.
