Function Application
‑525‑
A large value of this parameter enhances the anti‑interference capability, but slows
down the response to adjustments. A small value of this parameter speeds up the
response to adjustments, but weakens the anti‑interference capability. When onsite
pulse signal is subject to interference, increase the filter time to stabilize the detected
pulse signals. However, long filter time slows down the response to pulse signal
detection. Therefore, set the filter time based on the actual application environment.
3.1.3 Start/Stop Mode
3.1.3.1 Startup Modes
The AC drive supports three start modes: direct start, flying start, and pre‑excitation
start. Set F6‑00 to select a start mode for the AC drive.
Direct Start
When F6‑00 is set to 0, the AC drive uses the direct start mode. This mode is
applicable to most loads.

Start with the startup frequency is applicable to lifting loads, such as elevators and
cranes.
