Unused Channel Setting (Buffer Memory Address 61, 93: Un\G61, Un\G93); Pid Constant Read Command From Feram (Buffer Memory Address 62, 94: Un\G62, Un\G94) - Mitsubishi Electric MELSEC-Q Series User Manual

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

3.5.33 PID constant read command from FeRAM
(buffer memory address 62, 94: Un\G62, Un\G94)
3 - 97
(1) This setting is used for making unused channels where the PID control will not
be performed and sensors will not be connected.
• Used : Set 0 (default).
• Unused : Set 1.
(2) For the channels set as unused, the ALM LED will not flash even if a sensor is
not connected.
(3) When Default setting registration start command (Yn9) is turned on, the value
returns to a default value.
If there is any channel where the PID control is not performed or a sensor is not
connected, change the value and set the channel as unused.
(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)
Derivative time (D)
Loop disconnection detection judgment time
(2) This function is useful to use the initial setting of GX Configurator-TC and the
PID constants stored in FeRAM together.
Using this function, the items set in the initial setting of GX Configurator-TC at
the Q62HLC startup can be changed afterwards.
(3) When this command is set to 1 (With command), do not change the setting value,
backup data in FeRAM, or perform default setting registration.
(4) To execute auto tuning, set 0 (Without command). If auto tuning is executed with
a setting value 1 (With command), auto tuning will not complete even if internal
processing of auto tuning completes and PID constants are stored. (Auto tuning
status flag (Xn4, Xn5) does not turn off.)
