This parameter is used to determine the resolution of all related frequency parameters.
When the frequency resolution is 0.1Hz, PI500 maximum output frequency can reach
3200Hz, when the frequency resolution is 0.01Hz , PI500 maximum output frequency is
320.00Hz.
Note: when modifying the function parameters, the number of decimal places of all related
frequency parameters will change displayed, the frequency value will change accordingly.

Select inverter master reference frequency input channels. There are 10 master reference
frequency channels in all:
0: Keyboard set frequency (F0.01, UP/DOWN can be modified, power-down without
memory)
Initial value for the set frequency is F0.01 "preset frequency" value. The set frequency
value of the inverter can be changed by using the ▲ key and ▼ key on the keyboard (or multi-
function input terminals UP, DOWN).
The Inverter powers down and then powers on again, the set frequency value will be
recovered as F0.01 "digital preset frequency value".
1: Keyboard set frequency (F0.01, UP/DOWN can be modified, power-down with memory)
Initial value for the set frequency is F0.01 "preset frequency" value. The set frequency
value of the inverter can be changed by using the ▲ key and ▼ key on the keyboard (or multi-
function input terminals UP, DOWN).
The Inverter powers down and then powers on again, the set frequency value is same as the
frequency of the last power-down
Please note that F0.09 is for "digital set frequency stop memory selection ”, F0.09 is used to
select SAVE or CLEAR frequency correction when the inverter stops Besides, F0.09 is not
related to the power-down memory but shutdown.

3: Analog AI2 setting
4: Panel potentiometer setting
6: Multi-speed operation setting
When multi-stage command operation mode is selected, the different input state combination of
DI terminal correspond to the different set frequency value. PI500 can set up more than 4 multi-
stage command terminals and 16 statuses, and any 16 "multi-stage commands "can be achieved
correspondence through E1 group function code, the "multi-stage command" refers to the percent
of F0.19 relative to maximum frequency.
Under the mode, DI terminal function in F1 group parameters will be required to set as the
multi-stage command.
7: Simple PLC program setting
Under the mode, the inverter operating frequency source can be switched between 1 to 16 any
