P6.03
=
5.00Hz means the startup frequency is 5.00Hz.
P6.04
=
2.0s means that the startup frequency retention time is 2.0s.
In this case, the inverter will be in the standby status and its output frequency is 0Hz.
Example 2
:
P0.03
=
0 means the frequency source is digital reference.
P0.08
=
10.00Hz means the digital setup frequency is 10.00Hz.
P6.03
=
5.00Hz means the startup frequency is 5.00Hz.
P6.04
=
2.0s means that the startup frequency retention time is 2.0s.
In this case, the inverter accelerates to 5.00 Hz and remains for 2 seconds, and then accelerates to
the setup frequency 10Hz.

★
Pre-excitation is used to establish asynchronous motor magnetic field before startup, which would
improve response speed.
Start dc current braking is only valid when it is direct startup. Inverter first carries out dc braking
according to the setup of start dc current braking , and then carries out operation after start dc braking
time.
If dc braking time is set to 0, inverter directly start without dc braking. The bigger the dc braking current
is , the greater the braking force is.
If start mode is asynchrounous motor pre-excitation start, inverter first establish magnetic field through
pre-excitation current setup, then start to run after pre-excitation time. If set pre-excitation time to 0,
inverter would directly start without pre-excitation process./
Start dc braking current/pre-excitation current is the relative percentage of rated current.

It is used to select the frequency change mode during the inverter start and stop process.
0
:
Straight acceleration/ deceleration
The output frequency increases or decreases along the straight line. HV590 series inverter provides 4
types of acceleration/deceleration time.It can select acceleration/ deceleration time via the multifunctional
digital input terminals.
1
:
S-curve acceleration/ deceleration mode A
The output frequency increases or decreases along the straight line. S curve is generally used in the
applications where start and stop processes are relatively gentle, such as elevator and conveyor belt.The
acceleration/ deceleration time is consistent with the straight acceleration/ deceleration time.Function
codes of P6.08 and P6.09 can be respectively definedthe time proportion of starting-segment and finishing-
segment for S-curve acceleration/ deceleration.

Function code of P6.08 and P6.09 can be respectively defined the time proportion between the S-
curve initial-segment and finishing-segment for S-curve acceleration/ deceleration A. They are required to
meet the standard of P6.08+P6.09≤100.0%.
t1 in the Fig.5-11 is the parameters defined by P6.08, in this period of time which the changing slope
of output frequency is becoming larger and larger. t2 is defined by parameter P6.09, in this period of time
