7-3 Description of Functions
Frequency
Time
● 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 input 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.
