2.13 FC Multi-reference and Simple PLC
FC-00
Multi-reference 0
Address:
0xFC00
Min.:
‑100
Unit:
%
Max.: 100 Data type: Int16
Default:
0
Change: In real time
Value Range:
‑100.0% to +100.0%
Description
This parameter indicates the frequency reference of each speed. FC‑00 to FC‑15
correspond to 16 (from 0 to 15) frequency setting values. The frequency setting
values are calculated as percentages corresponding to the maximum frequency.
The value 100% corresponds to F0‑10 (Maximum frequency). The AC drive
provides four multi‑reference terminals, which have 16 state combinations,
corresponding to 16 frequency setting values.
When the simple PLC is used as the main frequency source, you need to set
parameters in group FC. In some industrial applications, the AC motor is only
used to realize the functions of start/stop, time‑ and segment‑based speed
regulation, and simple automatic forward and reverse run. A PLC is required for
other control functions. However, the simple PLC is able to provide the control
functions without a PLC. Simple PLCs are typically used in industrial equipment
such as mixture mixing and industrial washing machines. When the simple PLC is
used as the main frequency (F0‑03 = 7),
the parameters in group FC need to be set.
