KE300A Inverter Parameter Description
109
P6-03
Start frequency
Factory default
0.00Hz
Setting range
0.00Hz ~ 10.00Hz
P6-04
Start frequency holding time
Factory default
0.0s
Setting range
0.0s ~ 100.0s
Set proper start frequency can increase the start torque.
If the reference frequency is less than start frequency, inverter will be at stand-by status, and has no
output.
The start frequency could be less than the lower frequency limit.
P6-04 takes no effect during FWD/REV switching.
Example 1:
P0-03=0
Frequency source is digital reference
P0-08=2.00Hz
Digital setting frequency is 2.00Hz.
P6-03=5.00Hz
Start frequency is 5.00Hz.
F6-04=2.0s
Start frequency holding time is 2.0s.
At this time, the inverter is at standby status, and the output frequency is 0Hz.
Example 2:
P0-03=0
Frequency source is digital setting.
P0-08=10.00Hz
Digital setting frequency is10.00Hz.
P0-03=5.00Hz
Start frequency is 5.00Hz.
P0-04=2.0s
Start frequency holding time is 2.0s.
At this time, the inverter accelerates to 5Hz, and further to the reference frequency 10Hz in 2s.
P6-05
DC braking current before start/pre-excitation
current
Factory default
0%
Setting range
0% ~ 100%
P6-06
DC braking time before start/pre-excitation time
Factory default
0.0s
Setting range
0.0s ~ 100.0s
DC braking is used to make the running motor stop & restart. Pre-excitation is used to establish
asynchronous motor magnetic field, then start, improve the response speed.
DC braking is only valid when start directly, the inverter performs DC braking according to P6-05 firstly, and
runs after P6-06. If DC braking time is 0, the inverter starts directly. The bigger the DC braking current is,
the greater the braking force is.
If the start mode is pre-excitation start, then the inverter establishes magnetic field according to the set
pre-excitation current firstly, runs after the set pre-excitation time. If the pre-excitation time is 0, the inverter
starts directly.
DC braking current before start/pre-excitation current refers to the percentage of the inverter rated current.
P6-07
ACC/DEC mode
Factory default
0
Setting range
0
Linear ACC/DEC
