Fmax indicates the maximum setting frequency permitted by inverter. Range of Fmax:
20.00
～
600.00.
F0-17
Fup indicates the maximum frequency permitted to run after inverter start-up. Range of
Fup: Fdown~Fmax.
F0-18
Fdown indicates the minimum frequency permitted to run after inverter start-up.
Range of Fdown: 0.00Hz~Fup.
1. Upper limit frequency and lower limit frequency should be set prudently as per
the actual parameters listed on the nameplate of controlled motor and operational
status. Do not make the motor run for a long time in the lower frequency status.
Otherwise, the service lifespan of motor will be reduced due to overheating.
2. Correlation of maximum frequency, upper limit frequency, and lower limit frequency:
0.00Hz≤Fdown≤Fup≤Fmax≤600.00Hz
