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.
2: Analog AI1 setting
3: Analog AI2 setting
4: Panel potentiometer setting
Refers to that the frequency is determined by the analog input terminal, PI9000 control
panel provides two analog input terminals (AI1, AI2).
Either 0V to 10V voltage input or 0mA to 20mA current input, it is selected by the
jumper on the control board.
The corresponding relationship between AI1, AI2 input voltage value and the target
frequency can be set through F1 function code by user.
Panel potentiometer analog input voltage of 0V to 5V.
5: High-speed pulse setting
Frequency reference is achieved via terminal pulse reference. Pulse reference signal
specifications: voltage range of 9V to 30V, frequency range of 0 kHz to 100kHz. Pulse
reference only can be inputted from the multi-function input terminal DI5. The relationship
between DI5 terminal input pulse frequency and its corresponding setting can be set by F1.26
to F1.29, the correspondence is based on a straight line between 2 points, the pulse input
corresponds to the set 100.0%, , it refers to the percent of F0.19 relative to maximum
frequency
6: Multi-speed operation setting
