Multi-segment instructions can be used in three cases: as a frequency source, as VF
separation of the voltage source, as the process PID set the source.
In the three applications, the dimension of the multi-segment instruction is the relative
value, the range is -100.0% ~ 100.0%, which is the percentage of the relative maximum
frequency when it is the frequency source. When the VF is the isolated voltage source,
Percentage; and since the PID reference is originally a relative value, the multi -segment
instruction as the PID setting source does not require dimension conversion.
Multi-segment instructions need to switch according to the different state of multi-
function digital S, please refer to the relevant instructions for the P4 group.

Set range
Simple PLC functions have two functions: as a frequency source or as a voltage source
for VF separation.
Figure 6-30 is a schematic diagram of a simple PLC as a frequency source. Simple PLC
as a frequency source, PC-00 ~ PC-15 positive and negative determine the direction of
operation, if the negative value that the inverter running in the opposite direction.
As a frequency source, PLC has three operating modes, as VF separation voltage source
does not have these three ways. Among them:
