Adjusting Speed Setting Signal - Omron VS mini J7 User Manual

Adjusting speed setting signal

To provide frequency reference by analog input of control circuit terminal FR or
FC, the relationship between analog input and frequency reference can be set.

• Frequency reference gain (n41)
The analog input voltage value for the max (10V). 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 0V (4mA or 0mA)
can be set in units of 1%. (max. output frequency n09=100%)
Factory setting : 0%
