Ex.1:
H= (VI/II input), H= (disabled)
Output frequency = Reference frequency + Override (VI/II input [Hz])
Ex.2:
H= (VI/II input), H= (disabled)
Output frequency = Reference frequency + Override (VI/II input [Hz])
2) Multiplicative override
In this mode, each output frequency is multiplied by an externally override frequency.
[Ex.1: RR/S4 (Reference frequency), VI/II (Override input)] [Ex.2: RX (Reference frequency), VI/II (Override input)]

Ex.1:
H= (Disabled), H= (VI/II input), HOQF=(RR/S4 input), HJ=, WN=

VI/II input (H=, H=, H=, H=)
⇒ Setting of RR/S4 input: Refer to Section 7.3.1, Setting of VI/II input: Refer to Section 7.3.2.
Output frequency = Reference frequency × {1 + Override (VI/II input [%]/100)}
Ex.2:
H= (Disabled), H= (VI/II input), HOQF= (RX input), HJ=, WN=
RX input (H=, H=, H=, H=)

⇒ Setting of RX input: Refer to Section 7.3.3, Setting of VI/II input: Refer to Section 7.3.2.
Output frequency = Reference frequency × {1 + Override (VI/II input [%]/100)}
