(6) Condition to perform PID control
The condition to be able to perform PID control
*1
depends on the settings of the followings.
Setting/operation mode instruction (Yn1) ( Page 56, Section 3.3.3 (1))
PID continuation flag (Un\G169)) ( Page 131, Section 3.4.2 (43))
•CH PID control forced stop instruction (YnC to YnF) ( Page 58, Section 3.3.3 (7))
•CH Stop mode setting (Un\G33, Un\G65, Un\G97, Un\G129) ( Page 103, Section 3.4.2 (13))
The following table shows the relationship between the status of PID control
*1
and each of the settings above.
: Performed ×: Not performed
*1 Here, this is the generic term for two-position control, P control, PI control, PD control, and PID control.
*2 For the timing of each, refer to Page 50, Section 3.3.2 (2).
Even though the conditions above are met, PID control is not performed when CH Unused channel setting
(Un\G61, Un\G93, Un\G125, Un\G157) is set to Unused (1). ( Page 126, Section 3.4.2 (35))
The manipulated value (MV) and manipulated value (MV) for output with another analog module of when CH PID control
forced stop instruction (YnC to YnF) is turned on from off are as follows.
When CH PID control forced stop instruction (YnC to YnF) is turned off from on, the forced stop of PID control is released.
After the release, PID operation starts from the beginning.
