source is set in F0-18, as follows:
1 Main f
requency source X: The main frequency source is directly used to set the target
running frequency.
2 Au[iliary f
requency source Y: The au[iliary frequency source is directly used to set the
target running frequency.
3 X and Y superposition: The taget running frequency is set by means of X and Y
superposition.
4 Frequency switchover: A DI terminal is used to switch over between the preceding
three frequency setting channels.
The following figure shows how to set the relationship in F0-18, in which the bold line
indicates the default setting.
