The override functions calculate output frequency by the following expression:
Frequency command value × (1+ )+Value [Hz] selected with
f660
1) Additive override
In this mode, an externally input override frequency is added to operation frequency command.
[Ex.1: VIA (Reference frequency), VIC (Override input)] [Ex.2: VIB (Reference frequency), VIA (Override input)]
Ex.1:
f660=3 (VIC input), f661=0 (disabled)
Output frequency = Reference frequency + Override (VIC input [Hz])
Ex.2:
f660=1 (VIA input), f661=0 (disabled)
Output frequency = Reference frequency + Override (VIA input [Hz])
