5 Basic Settings
Using an Analog Voltage Input or Analog Current Input by Switching
To switch between analog voltage and analog current inputs to set the frequency reference, set the
parameters as follows.
This enables switching between the frequency reference input (voltage reference) and frequency
reference input (current reference) terminals.
To switch between these analog input signals, use the terminal AT (Analog input switching) allocated to
a multi-function input terminal.
V
• Frequency reference input (Voltage reference), between terminal FV and FC: 0 to 9.8 VDC
• Frequency reference input (Current reference), between terminal FI and FC: 4 to 19.8 mA
Note By default, each analog input signal is set to reach the maximum frequency at 9.8 V or 19.8 mA.
