Analog input setting - compressor application
RVBS supports the frequency command to source external analog voltage input port which allows 0V to 10V
by setting F01=1. The analog input is processed to be used for frequency reference following next parameters
setting: - Analog Input Voltage Offset (C10) C10 specifies real time editable offset factor for analog input
voltage. - Analog Input Voltage Gain (C11) C11 specifies real time editable gain factor for analog input voltage.
- Frequency at Minimum Analog Input (C12) When Frequency Command Source is set to the Analog input
(F01=1), this parameter determines the Analog input frequency reference (D17) at minimum analog input
voltage, 0 V. - Frequency at Maximum Analog Input (C13) When Frequency Command Source is set to the
terminal input (F01=1), this parameter determines the Analog input frequency reference (D17) at maximum
analog input voltage, 10 V.
- Minimum Analog Input Offset (C14) C14 specifies offsets the minimum analog input reference corresponding
to C12.
➢
Example: if set to 10%, minimum analog voltage value becomes 1 V.
- Maximum Analog Input Offset (C15) C15 specifies offsets the maximum analog input reference
corresponding to C13.
➢
Example: if set to 90%, maximum analog voltage value becomes 9V. For any reference above C15,
the inverter holds the value in C13.
