(1) With this function, the PID constants set at completion of auto tuning are backed
up automatically by E
When 1 is written to this setting and auto tuning then started, data at the following
buffer memory addresses are automatically backed up by E
of auto tuning.
Buffer memory address name
Proportional band (P) setting
Integral time (I) setting
Derivative time (D) setting
Loop disconnection detection
judgment time
(2) Do not change this setting during execution of auto tuning.
(3) While auto tuning is being executed with this setting valid, do not make a set value

change, E PROM backup and default setting registration.
Sets the dead band for alerts.
Set it within the range 0 to 100 (0.0% to 10.0%) to the full scale of the set input range.
Example) When the input range 2 (0 to 1300°C) and alert dead band setting 5 (0.5%)
are selected
(Full scale)
For details, refer to Section 3.2.11 (2).
(1) Sets the sampling count for judging an alert.
When the alert delay count has been set, the system is placed in an alert status if
the sampling count remains within the alert range between when the process
value (PV) has fallen within the alert range and when the sampling count reaches
or exceeds the alert delay count.
Refer to Section 3.2.11 for details.
(2) The setting range is 0 to 255.
H
(1) Available only for the Q64TCTTBW and Q64TCRTBW.
(2) Sets how many heater disconnection detection and output off-time current
detection errors will occur consecutively before alert judgment is made.
(3) The setting range is 3 to 255.
