M+M_Pidp_Ex_T; Position Type Pid Control (Disable Tracking For Primary Loop/Enable Tracking From Secondary Loop) - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

12.13
Position Type PID Control (Enable Tracking for
primary loop/Enable Tracking from secondary
loop) (M+M_PIDP_EX_T_)

M+M_PIDP_EX_T_

This FB performs position type PID control combining the functions of M+P_IN, M+P_PHPL, and M+P_PIDP_EX_T_ into a
single FB.
It also allows manipulated value bumpless switching and tracking from the primary loop and secondary loop at a change of
control mode.
