*1. The inverter operates at –10 to 10 V when both A111 and A112 are set to 0.00.
0.00 Hz
A112 FE End Frequency
A113 FE Start Ratio
–100. to FE End Ratio
(Set a start ratio relative to an external
frequency reference of –10 to 10 V)
*2
*2. The ratio relative to an external frequency reference of –10 to 10 V is as follows.
· –10 to 0 V: –100% to 0%
· 0 to 10 V: 0% to 100%
For example, to use an external frequency reference of –5 to 5 V between the FE and FC terminals, set A113 to
–50% and A114 to 50%.
0.

A114 FE End Ratio
FE Start Ratio to 100.
(Set an end ratio relative to an external
frequency reference of –10 to 10 V)
