3.4 A Group Parameters
A group holds extended frequency control Parameters and VFD operational Parameters.
A01 Frequency Setpoint Source
0: Potentiometer on keypad
1: Control Terminal Input (O-L: Voltage, OI-L: Current)
2: Up/Down Keys on keypad
3: Remote Operator 1 (RJ45 Port, RS485 Communication), Except 300LF~750LF
4: Remote Operator 2 (RXP-RXN, RS485 Communication)
5: Fieldbus (option)
Determined the source of the frequency command.
Related Parameters: F01, A05~A10, A61~A64, b17, b28~b29, b31
A02 Run Source
0: Run/Stop Key on keypads
1: Control Terminal Input ((FW, RV Connect)
2: Remote Operator 1 (RJ45 Port, RS485 Communication), Except 300LF~750LF
3: Remote Operator 2 (RXP-RXN, RS485 Communication)
4: Fieldbus (option)
Determined the source of the run command.
Related Parameters: F04, d06, C1~C12, b17, b28~b29, b31
A03 Base Frequency Setpoint
Range: 0.00 ~ Maximum Frequency(A04) in 0.01 Hz
Frequency at which the maximum voltage is reached.
Should be set to the motor rated frequency.
Related Parameters: None
A04 Maximum Frequency Setpoint
Range: A03 ~ 400.00 Hz in 0.01 Hz
If Sensorless Vector Control (A31=2): Base Frequency (A03) ~ 300 Hz in 0.01 Hz
Maximum frequency the VFD will output.
Related Parameters: F02, F03
A05 Frequency at Min. Analog Input
Range: 0.00 ~ Maximum Frequency(A04) in 0.01 Hz
When Frequency Command Source is set to the terminal input (A01=1), this parameter
determines the Frequency Setpoint (F01) at minimum analog input current, 4mA (or
voltage, 0 V)
Related Parameters: A01, A07
A06 Frequency at Max. Analog Input
Range: 0.00 ~ Maximum Frequency(A04) in 0.01 Hz
When Frequency Command Source is set to the terminal input (A01=1), this parameter
determines the Frequency Setpoint (F01) at maximum analog input current, 20mA (or
voltage, 10 V)
Related Parameters: A01, A08
