Adjusting Speed Setting Signal
The relationship between the analog inputs and the frequency reference
can be set to provide the frequency reference by analog input of control
circuit terminal FR or FC.
• Frequency reference gain (n41)
The analog input voltage value for the max. output frequency (n09)
can be set in units of 1% (max. output frequency n09=100%).
* Factory setting: 100%
• Frequency reference bias (n42)
The frequency reference provided when analog input is 0 V (4 mA
or 0 mA) can be set in units of 1% (max. output frequency
n09=100%).
* Factory setting: 0%
Typical Settings
• To operate the Inverter with a frequency reference of 50% to
100% at an input voltage of 0 to 5 V
( ) indicates the value when a current
reference input is selected.
