When main frequency reference and auxiliary frequency reference are used for calculation (nal
frequency reference is set by "main and auxiliary calculation"), pay attention to the following
aspects:
● If auxiliary frequency reference is digital setting, preset frequency (F0-08) does not take
effect. You can directly adjust auxiliary frequency reference by pressing keys
and
on the operating panel (or using the UP/DOWN function of input terminals) based on main
frequency reference.
● If auxiliary frequency reference is set via analog input (AI1, AI2 and AI3) or pulse reference,
100% of the input corresponds to range of the auxiliary frequency reference (set in F0-05
and F0-06). This is valid for main and auxiliary calculation.
● Main frequency reference and auxiliary frequency reference must not use the same setting
channel. That is, F0-03 and F0-04 cannot be set to the same value.
● Main & auxiliary calculation can be used for closed-loop speed control. An example of this is
to use main frequency reference to set a required frequency reference and to use auxiliary
frequency reference for automatic adjustment. Closed-loop control is implemented when this
method is used with switchover performed by an external DI terminal signal.
