100.00%.
F09.02=5: PULSE high-frequency pulse (X5)
The set percentage of PID is directly dependent on the HDI (percentage).
For the details of AI1-AI2 and X5, see the description of F00.04. When used as the PID
setting, the percentage will directly turn the set value, and the maximum output is 100.00%.
F09.02=6: communication setting
The PID feedback percentage is directly dependent on the communication (percentage).
If the master-slave communication (F10.05=1) is enabled and the inverter works as the
slave (F10.06=0), the specific feedback percentage is “700FH (master-slave
communication setting) * F10.08 (slave receiving proportional coefficient)”, and the
700FH data range is -100.00% to 100.00%, as detailed in Table 12-31.
For the general communication (F10.05=0), the specific feedback percentage is “7005H
(communication setting of process PID feedback)”, and the 7005H data range is
-100.00% to 100.00%, as detailed in Table 12-31.
