● Each PID command value can be gained by F3013 (PID1)/F3113 (PID2).
● Each PID command value will be limited according to the upper frequency limit after the gain, then acceleration/deceleration will
be processed.
When PID command value is beyond the frequency setting, the acceleration/deceleration time will be based on reference
frequency: F1011 is the reference, run the operation according to 3
Note 1: The PID control of acceleration/deceleration (beyond the frequency setting) will share the 3
acceleration/deceleration time used in normal operation, this is a fixed use.
Note 2: During the 3
acceleration/deceleration will not be carried, the PID command target value will be directly used as PID
command value.
The following shows the formation of PID command value.

Note 3: The judgment of inverter startup condition is not the command values of PID, like the normal operation, it is
determined by the status of target frequency, start frequency and operation startup frequency.
Therefore, when the setting is beyond the frequency of F3001/F3101≠1, the input switching of PID command
value during operation startup is required to set the multi-speed target frequency larger than start frequency
and operation startup frequency.
Note 4: PID command value input switching: when the setting is beyond the frequency of F3001/F3101≠1, since the
control value is different from normal frequency command, the functions based on normal frequency will not
work, such as acceleration/deceleration characteristics, constant-speed protection, speed tracking and so on.
Please pay attention to this.

The function to select the feedback value of PID control.
The function to select feedback input, F3002 for PID1 and F3102 for PID2.
● Select the following PID feedback value in the settings of F3002/F3012.
· F3002/F3012=0: no input
When the feedback input is not selected, the PID control selected by PID1 and PID2 will be noneffective. The normal open
loop operation will be carried out.
· F3002/F3012=1~9: various analog feedback input values (VIF1~VIF3)
Input feedback value through various analog inputs (VIF1~VIF3).
Analog input is the same as normal frequency command, the input value will be switched into frequency by gain frequency
and bias frequency of F1401~F1406, this frequency will be used as feedback value for PID control.
· F3002/F3012=10: the values set by F3018 (PID1)/F3118 (PID2) are the feedback values.
When feedback value is input by communication function, please enter the data in F3018 (PID1)/F3118 (PID2).
The values set by F3018 (PID1)/F3118 (PID2) are switched into frequency by the frequency set by F3019 (PID1)/F3119
(PID2).
The maximum value (6000) of F3018 (PID1)/F3118 (PID2) will be switched into the frequency set by F3019 (PID1)/F3119
(PID2).
Example) When F3118=1200 and F3119=100Hz, the feedback value of PID2 is 20Hz.
· F3002/F3012=99: The speed is switched into frequency by PG feedback pulse input (A+, A-/B+, B- terminals), the
frequency will be used as feedback value input.
For PG feedback pulse input and setting method, please refer to Chapter 4 "Connection of PG Sensor" and "Function
