The override functions calculate output frequency by the following expression:
Frequency command value × (1+
1) Additive override
In th1is mode, an externally input override frequency is added to operation frequency command.
[Ex.1: RR/S4 (Reference frequency), VI/II (Override input)] [Ex.2:RX (Reference frequency), VI/II (Override input)]
