Program Explanation
• When the input condition M2 turns on, PID auto tuning operation executes at no.0 parameter.
• When auto tuning finished, PID operation executes with calculated P,I,D parameter.
• PID execution status registrate D0000 and the output value of control result registrate D0001
• If SV Ramp is designated, current SV is registrate D0005
• D/A module converts the MV to analog signal and output to the actuator (power converter).
• When the input condition M2 turns off, output 0 to the D/A conversion module
When M0002 turns on, auto tuning starts.
Calculated P,I,D parameters are saved to D0002, D0003, D0004
When auto tuning ends,
M0001 turns on and PID control starts.
7-37
When M0002 turns off,
Output 0 to D4980
