• Adjusting speed setting signal
The relationship between the analog input signal and internal (terminal “FR”)
frequency reference can be set by parameters n41 and n42.
(a) Frequency reference gain (n41)
The analog input voltage level for the maximum output frequency (n09) can be set
in units of 1%. (maximum output frequency n09=100%)
∗ Factory setting : 100%
(b) Frequency reference bias (n42)
The frequency reference provided when the analog input is 0V (4mA or 0mA) can
be set in units of 1%. (Maximum output frequency n09=100%)
∗ Factory setting : 0%
Example settings:
• To operate the inverter with frequency reference of 0% to 100% at 0 to 5V input
FREQUENCY REFERENCE
Gain n41 = 200%
Bias n42 = 0%
