KE300A Inverter Parameter Description
100
P4-12
UP/DN change rate
Factory default
1.00Hz/s
Setting range
0.001Hz/s ~ 50.000 Hz/s
Terminals UP/DOWN is used to adjust the change rate when setting frequency.
When P0-22 is set to 2, the range is 0.001~50.000Hz/s.
When P0-22 is set to 1, the range is 0.01~50.00Hz/s.
P4-13
AI curve 1 minimum input
Factory default
0.00V
Setting range
0.00V ~ P4-15
P4-14
AI curve 1 minimum input
corresponding setting
Factory default
0.0%
Setting range
-100.00% ~ 100.0%
P4-15
AI curve 1 maximum input
Factory default
10.00V
Setting range
P4-13 ~ 10.00V
P4-16
AI curve 1 maximum input
corresponding setting
Factory default
100.0%
Setting range
-100.00% ~ 100.0%
P4-17
AI1 filter time
Factory default
0.10s
Setting range
0.00s ~ 10.00s
The above function codes define the relationship between the analog input voltage and analog input
setting value.
When the analog input voltage is bigger than P4-15 (maximum input of AI curve 1), then calculate the
analog voltage according to maximum input. When the analog input voltage is smaller than P4-13
(minimum input of AI curve 1), then calculate the analog voltage with minimum input or 0.0% according to
P4-34 (AI below minimum input setting selection).
When the analog input is current input, 1mA current equals to 0.5V voltage.
AI1 input filter time is used to set AI1 software filter time, when the site analog signal can be easily
disturbed, please increase filter time to stable the detected analog signal, but the bigger the filter time is,
the slower the response speed of the analog detection is . So please set this parameter according to the
situation.
In difference applications, 100% of analog input corresponds to different nominal values. Refer to all the
application parts for details.
Several setting examples are shown in the following figures:
