Note:
(1) The inverter has 7 Acc/Dec time. Herein just 1 Acc/Dec is defined. The other 2~7
Acc/Dec time are defined by P3.14~P3.25 function parameter.
(2) It can select time unit by P0.09 for all 1~7 Acc/Dec time. The factory default setting
unit is second.

P0.19,P0.20 parameter defines the upper and lower limit of output frequency. FH,FL is upper
limit frequency and lower limit frequency respectively shown as Fig.6-2.
When actual setting frequency is lower than lower limit freq., the inverter output frequency will
decrease in Dec time which has been set. As it reaches the lower limit frequency, if P0.21=0 ,
the inverter will run at lower limit frequency. If P0.21=1, the inverter will keep decreasing the
output frequency to 0.
