Control Mode (Buffer Memory Address 50, 82: Un\G50, Un\G82) - Mitsubishi Electric MELSEC-Q Series User Manual

3 SPECIFICATIONS

3.5.23 Control mode (buffer memory address 50, 82: Un\G50, Un\G82)

3 - 92
(1) A control mode (normal control mode, manual control mode, or program control
mode) is set.
• Normal control mode
• Manual control mode 1
• Program control mode
• Manual control mode 2
*1: The settings and setting ranges of MAN output setting differ between the
manual control mode 1 and 2 (refer to Section 3.5.24).
(2) The mode switching completion can be checked with Control mode monitor
(buffer memory address: 30).
(3) When switching normal control/program control to manual control, the
manipulated value calculated in PID operations is transferred to MAN output
setting (buffer memory address: 51, 83) to prevent a sudden change of the
manipulated value. (Bumpless switching)
After the mode is switched, the value of Control mode monitor (buffer memory
address: 30) is updated.
The manipulated value of the manual control mode 1 and 2 should be set after
the updated value is checked.
(4) Select "Normal control mode" at auto tuning execution.
If any other mode is selected, auto tuning is not executed.
: Set 0.
The manipulated value calculated in PID
operations is used for control output.
The set value needs to be changed manually.
: Set 1.
The manipulated value written in MAN output
setting (buffer memory address: 51, 83) is used
*1
for control output.
: Set 2.
The control is performed changing the set value
automatically in accordance with the program
pattern. The manipulated value calculated in PID
operations is used for control output.
: Sets 3.
The manipulated value written in MAN output
setting (buffer memory address: 51, 83) is used
*1
for control output.
