Parameter description
Reversible switching process, starting frequency holding time does not work. Start frequency holding time is not included in
the acceleration time, but is included in the running time of simple PLC.
Example 1:
P0-03＝0 Frequency source is digital given
P0-08＝2.00Hz
P6-03＝5.00Hz
P6-04＝2.0s Start frequency holding time is 2.0s At this time, the inverter is in the standby state, the inverter output
frequency is 0.00Hz.
Example 2:
P0-03＝0 Frequency source is digital given
P0-08＝10.00Hz
P6-03＝5.00Hz
P6-04＝2.0s Start frequency retention time 2.0s
At this time, the drive accelerates to 5.00Hz, continued to 2.0s, and then accelerated to a given frequency 10.00Hz.
P6-05
Starting DC braking time / pre-excitation time
P6-06
DC brake is generally used to stop and start the motor running. Pre-excitation is used to make the magnetic field
induction motor and then start to establish and improve the response speed.
DC brake is valid only in the start mode is direct start. This time the frequency setting press Start DC braking current
DC braking, DC braking time after the start and then start running. If the DC braking time is set to 0, no start directly after
DC braking. DC braking current increases, the greater the braking force.
If the startup mode for the asynchronous motor pre-excitation start, the drive set in the pre-press pre-established
magnetic field current, after the set pre-magnetizing time before starting to run. If the set pre-magnetising time is 0, no pre-
excitation processes started directly.
DC brake current / pre-excitation current, the percentage relative to the rated drive current.
P6-07
Select the drive frequency change in the start and stop the process of moving way.
0: Linear acceleration and deceleration The output frequency linear increment or decrement. This provides four kinds of
acceleration and deceleration time. Can be selected via multifunction digital input terminals (P4-00 ~ P4-08).
1: S curve acceleration and deceleration A
Output frequency increases or decreases according to S curve. S curve requires gentle place to start or stop the use, such as
elevators, conveyor belt. P6-08 and P6-09 respectively function code defines the time ratio of S curve acceleration and
deceleration of the initial segment and the end segment
2: S curve acceleration and deceleration B
In the S-curve acceleration and deceleration B, the motor rated frequency f is always the inflection point of the S-curve.
Shown in Figure 6-12. Generally used for high speed area above the rated frequency requires rapid acceleration and
deceleration of the occasion.
