HV580L Series Frequency Inverter
124
P6-03
=
5.00Hz The startup frequency is 5.00 Hz.
P6-04
=
2.0s
The startup frequency holding time is 2.0s.
In this example, the AC drive stays in the standby state and the output frequency is 0.00 Hz.
Example 2
:
P0-03
=
0 The frequency source is digital setting.
P0-08
=
10.00Hz The digital setting frequency is 10.00 Hz.
P6-03
=
5.00Hz The startup frequency is 5.00 Hz.
P6-04
=
2.0s
The startup frequency holding time is 2.0s.
In this example, the AC drive accelerates to 5.00 Hz, and then accelerates to the set frequency 10.00 Hz after 2s.
Startup DC braking is generally used during restart of the AC drive after the rotating motor stops.
Pre-excitation is used to make the AC drive build magnetic field for the asynchronous motor before startup to
improve the responsiveness.
Startup DC braking is valid only for direct start (P6-00 = 0). In this case, the AC drive performs DC braking at
the set startup DC braking current. After the startup DC braking time, the AC drive starts to run. If the startup
DC braking time is 0, the AC drive starts directly without DC braking. The larger the startup DC braking current
is, the larger the braking force is.
If the startup mode is pre-excited start (P6-00 = 3), the AC drive builds magnetic field based on the set
pre-excited current. After the pre-excited time, the AC drive starts to run. If the pre-excited time is 0, the AC
drive starts directly without pre-excitation.
The startup DC braking current or pre-excited current is a percentage relative to the base value.

Linear acceleration/deceleration

S-curve acceleration/deceleration A
2
S-curve acceleration/deceleration B
It is used to set the frequency change mode during the AC drive start and stop process.
0: Linear acceleration/deceleration
The output frequency increases or decreases in linear mode. The HV580L provides four group of
acceleration/deceleration time, which can be selected by using P4-00 to P4-08.
• 1: S-curve acceleration/deceleration A
The output frequency increases or decreases along the S curve. This mode is generally used in the
applications where start and stop processes are relatively smooth, such as elevator and conveyor belt. P6-08
and P6-09 respectively define the time proportions of the start segment and the end segment.
