SV600 Series User Manual 7 Parameter Description
79
When the simple programmable logic controller (PLC) mode is used as the frequency source,
the running frequency of the inverter can be switched over among the 16 steps. You can set the
holding time and Acc./Dec. time of each step. For details, refer to the descriptions of Group PC.
8: PID
The output of PID control is used as the running frequency. When applying PID as the
frequency source, you need to set parameters of PID function in group PA.
9: Communication setting
The frequency is set by MODBUS communication. For more details, please refer to description
of MODBUS communication the manual.

When used as an independent frequency input channel, the auxiliary frequency source Y is used
in the same way as the main frequency source X (refer to P0-03).
When the auxiliary frequency source is used with main frequency X together, pay attention to
the following aspects:
1) If the auxiliary frequency source Y is digital setting, the preset frequency (P0-08) does not
take effect. You can directly adjust the set main frequency by pressing UP and DOWN arrow
keys on the keyboard (or using the multi-function DI input terminals with UP/DOWN function).
2) If the auxiliary frequency source is analog input (AI1, AI2) or pulse setting, 100% of the
input corresponds to the range of the auxiliary frequency Y (set in P0-05 and P0-06).
3) If the auxiliary frequency source is pulse setting, it is similar to analog input.
Note: The main frequency source X and auxiliary frequency source Y must not use the same channel. That is,
P0-03 and P0-04 cannot be set to the same value.

If main frequency X and auxiliary frequency used together, P0-05 and P0-06 are used to set the
adjustment range of the auxiliary frequency source.
You can set the auxiliary frequency to be relative to either maximum frequency or main
frequency X. If relative to main frequency X, the setting range of the auxiliary frequency Y
varies according to the main frequency X.
