0: Valid, and the inverter memorizes when power down. Able to set up frequency
command, and memorize this set frequency when the inverter is power down. When the power
is back, automatically combine it with current frequency setting.
1: Valid, and the inverter does not memorize when power is down. Able to set up
frequency, but when the inverter power is down, this frequency setting is not memorized.
2: Invalid. The frequency set through keyboard and terminal UP/DOWN is automatically
cleared, and the settings through keyboard and terminal UP/DOWN are invalid.
Note: After the user restores the default values of inverter function parameters, the
frequency value, set through keyboard and terminal UP/DOWN, is automatically
cleared.

Selection of inverter frequency command A input channels. There are 8 main frequency
setting channels:
0: Keyboard setting
Accomplish keyboard frequency setting by means of modifying the value of function code
P0.10 “Keyboard frequency setting”.
1
Analog AI1 setting
2
Analog AI3 setting
This means that the frequency is set up through analog input terminals. CHV series
inverter standard configuration provides 2 analog input terminal paths, and besides, optional
multi-function I/O extension card can provide 2 analog input terminals (AI3 and AI4). Terminal
AI1, AI3 and AI4 are 0-10V voltage input mode, while AI2 can be 0-10V voltage input and also
can be 0 (4)-20mA amperage input. Voltage input and current input can be switched by
Jumper J18.
The 100.0% setting of analog input is corresponding to the maximum frequency (Function
Code P0.07), and -100.0% is corresponding to maximum reverse frequency (Function Code
P0.07).
3
High speed pulse setting (HDI1)
This means that inverter frequency setting is set through terminal high speed pulse input.
CHV series inverter standard configuration provides 1 path of high speed pulse input (HDI1),
and besides, optional multi-function I/O extension card can provide another one path of high
speed pulse input (HDI2).
Pulse setting signal Rating : pulse voltage range 15-30V, and pulse frequency range
0.0-50.0KHz.
The 100.0% setting of pulse input is corresponding to the maximum frequency (Function
Code P0.07), and also -100.0% is corresponding to the maximum reverse frequency (Function
Code P0.07).
