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
Hand On
3. Press 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
frequency will be stored as the first element in par.4-62
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

6. When the motor has ramped down to stop, press
ically reset to Off. The adjustable frequency drive will stay in
the keypad.
