Using an Analog Voltage Input or Analog Current Input
To use an analog voltage input or analog current input to set the inverter frequency reference, set the
parameters as follows.
This enables the frequency reference input (voltage reference) or frequency reference input (current
directive) terminal.
If inputs are made to both the frequency reference input (voltage reference) and frequency reference
input (current reference) terminals, the sum of the two analog input values will be set as the inverter
frequency reference.
V
• Frequency reference input (Voltage reference), between terminal FV and FC: 0 to 10 VDC
• Frequency reference input (Current reference), between terminal FI and FC: 4 to 20 mA
Note By default, each analog input signal is set to reach the maximum frequency at 9.8 V or 19.8 mA.
Parameter No.
