KE300A Inverter Parameter Description
84
KE300A series inverter offers three ACC/DEC time units, they are 1s, 0.1s, 0.01s.
Note: When modifying this function parameter, 4 group ACC/DEC time display decimal place
changes, the corresponding ACC/DEC time also changes.
P0-21
Auxiliary frequency source offset
frequency when combination
Factory default
0.00Hz
Setting range
0.00Hz ~ P0-10 (maximum frequency)
This function code is only valid when frequency source is set to be main/auxiliary calculation.
When frequency source is set to be main/auxiliary calculation, P0-21 is offset frequency, which can be
combined with main/auxiliary calculation result setting as reference frequency.
P0-22
Frequency command resolution
Factory default
2
Setting range
1
0.1Hz
2
0.01Hz
This parameter is used to determine the resolution of all the function codes related to frequency.
When frequency resolution is 0.1Hz, the MAX. output frequency is 3000.0Hz. When frequency resolution is
0.01Hz, the MAX. output frequency is 300.00Hz.
Note: When modifying this parameter, the decimal place of all the parameters related to frequency
changes, the corresponding frequency value changes too.
P0-23
Digital setting frequency storage
selection when stop
Factory default
1
Setting range
0
Not store
1
store
This function is only valid when frequency source is set by keypad
0: No store means that the keypad setting frequency value would recover to the value of P0-08 (preset
frequency) after the inverter stopped. The frequency modification by keys “
▲”, “▼” or terminal UP, DOWN
would be cleared.
1: Store means that the keypad setting frequency would recover to the last frequency when inverter
stopping. The frequency modification by
keys “▲”, “▼” or terminal UP, DOWN is valid.
P0-25
ACC/DEC time reference frequency
Factory default
0
Setting range
0
P0-10 (maximum frequency)
1
Setting frequency
2
100Hz
ACC/DEC time is ACC/DEC time from 0Hz to the frequency set by P0-25, figure 6-1 is ACC/DEC time
schematic diagram.
When P0-25 is set to 1, ACC/DEC time is related to setting frequency. The motor acceleration will change if
setting frequency changes frequently.
