3.5.32 Unused channel setting (buffer memory address 61, 93: Un\G61, Un\G93)

3.5.33 FeRAMs PID constant read command
(buffer memory address 62, 94: Un\G62, Un\G94)
3 - 78
(1) This setting is used for making unused channels where the PID control will not
be performed and sensors will not be connected.
• Used
: sets 0 (default value).
• Unused : sets 1.
(2) For the channels set as unused, the ALM LED will not be flicker even if a sensor
is not connected.
(3) Making default setting registration (Yn9: ON) turns the unused channel setting
into the default value (used).
When there are channels where the PID control is not performed and sensors
are not connected, make unused channel setting again after the completion of
default setting registration.
(1) This command reads PID constants from FeRAM to buffer memory.
Set this command to "1" (With command) to read FeRAM values to the following
buffer memory addresses.
Buffer memory address name
Proportional band (P) setting
Integral time (I) setting
Derivative time (D) setting
Loop disconnection detection judgment time
(2) This function is the most suitable for use when you want to use the initial settings
of the utility and the PID constants backed up on FeRAM together.
If you want to change afterwards the items set in the initial setting of GX
Configurator-TC at Q62HLC startup, reading from FeRAM with this command
can correspond to it.
(3) When this command is set to "1" (With command), do not perform a set value
change, FeRAM backup and default setting registration.
(4) When executing auto tuning, set 0 (Without command) to this command. If auto
tuning is executed while setting 1 (With command) to the command, even if
internal processing of auto tuning is completed and PID constant is stored, the
auto tuning status flag (Xn4, Xn5) does not turn OFF and auto tuning is not
completed.
