● IHOLD Signal:
The terminal to lock the integral operation of PID control and hold the integral value.
ON： Lock the integral operation of PID control and hold the integral value.
Don't clear integral value in ON, hold the previous value.
OFF： Carry out normal PID control.
● ICLEAR Signal:
The terminal to stop the integral operation of PID control and clear the integral value.
ON： Stop the integral operation of PID control and clear the integral value.
OFF：Carry out normal PID control.
Note: When clearing the integral output, sometimes the current output frequency may change rapidly.
【Timing Switch of PID Control】
The function to automatically switch from PID1 control to PID2 control within the preset time period.
● Use the following function code and input signals of external multi-function terminals (DI1~DI8).
Selection of PID control action
· F3201=5: switch the PID function timely.
PID1/PID2 switching time
· F3207=0.1～6000 minute(s): set the switching time.
RPID1 Signal
The terminal to forcibly switch the control into PID1 control after switching to PID2 control.
ON： Switch the control in PID2 control to PID1 control.
During this period, the time count of timing switch will be stopped.
OFF： Continue the time count for timing switch.
● When set F3201=5, the switch will be carried out automatically through PID1 and PID2 controls set by F3207.
The control will start from PID1 control, when setting time is reached, it will switch to PID2 control.
In PID2 control, if RPID1 signal is connected, it will return to PID1 control again.
If RPID1 signal is OFF, the timer for timing switch will continue to count and carry out the same action.
Note 1: During stop, the timer for timing switch will stop (hold). When power is OFF, the time on the timer will also be
recorded.
Note 2: After startup of the timer for timing switch, the timer will work.
Note 3: During operation of the timer for timing switch, when the settings of F3207 are changed, they will be switched into
changes.

【External Terminal Switching PID Control】
The external terminal switching PID control is the function to coordinate various PID controls and system status, and then make a
switch through the external terminals. It can be applied in the following systems.
⑴ When the motor load is changed and the controls in the same PID control are difficult.
⑵ When switching motor or load according to the status of the system.
Each PID control is selected by the selection of function code or external multi-function terminal input signal (DI1~DI8).
Use inverter as the component of the PID controller, this can control the external peripheral devices.
● Use the following function codes and external multi-function terminal input signals (DI1~DI8).
PID control action selection
·F3201=4: external terminal switching PID control
PIDH/PIDL Signal: PID switching terminal
With the status of the two terminals, the PID control will be switched as follows.
PID2 control
- 140 -
PID1 control
Stop
PID2 control
