It is used to bind the three running command sources with the nine frequency sources, facilitating to implement synchronous
switchover.
For details on the frequency sources, see the description of P0.04 (Main frequency source X selection).Different running command
sources can be bound to the same frequency source.
If a command source has a bound frequency source, when the process of frequency source is effective, the command source set
in P003 to P007 will no longer work.

Pre-excited start (asynchronous motor)
0: direct start
If the DC braking time is set to 0, the AC drive starts to run at the startup frequency. If the DC braking time is not 0, the AC drive
performs DC braking first and then starts to run at the startup frequency. II is applicable to small-inertia load application where
the motor is likely to rotate at startup.
1: Rotational speed tracking restart
The AC drive judges the rotational speed and direction of the motor first and then starts at the tracked frequency. Such smooth
start has no impact on the rotating motor. It is applicable to the restart upon instantaneous power failure of large-inertia load. To
ensure the performance of rotational speed tracking restart, set the motor parameters in group P2 correctly.
2: Pre-excited start (asynchronous motor)
It is valid only for asynchronous motor and used for building the magnetic field before the motor runs. For pre-excited current and
pre-
excited time, see parameters of P1.05 and P1.06. If the pre excited time is 0, the AC drive cancels pre
-excitation and starts to
run at startup frequency. If the pre-excited time is not 0, the AC drive pre-excites first before startling, improving the dynamic
response of the motor.
P1.01
Rotational speed tracking mode
Default
0
Setting Range
0
Start from stop frequency
1
From zero speed
2
From maximum frequency
To complete the rotational speed tracking process within the shortest time, select the proper mode in which the AC drive tracks
the motor rotational speed.
0: From frequency at stop to track down. It is the commonly selected mode.
1: From zero frequency to track down.
It is applicable to restart after a long time of power failure. 2: From the maximum frequency to track down.
It is applicable to the power-generating load.
P1.02
Rotational speed tracking speed
Default
20
Setting Range
1 ~100
In the rotational speed tracking restart mode, select the rotational speed tracking speed. The larger the value is, the faster the
tracking is. However, too large setting value may cause unreliable Tracking.
P1.03
Startup frequency
Default
0.00Hz
Setting Range
0.00Hz-10.00Hz
