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 fre Override (VIC input [Hz])
Ex.2:
f660
=
1
(VIA input),
f661
=
0
(disabled)
Output frequency = Reference fre Override (VIA input [Hz])
