(Auto-tuning Cancel)
SV
(Auto-tuning Perform)
[Factory adjusted as Auto-tuning Cancel]
If the Auto-tuning is released during the process,
the PID value reverts to the former value.
Proportional band setting
Mode to set the proportional band.
Setting value
Setting range: 0.1 to 999.9%
[Factory adjusted as 2.5%]
This display is not available when the ON/OFF action is
selected in Control action designation (page 10).
Integral time setting
Mode to set the integral time.
Setting value Setting range: 0 to 3600s
[Factory adjusted as 200s]
Setting the value to 0 disables the function.
This display is not available when the ON/OFF action or
PD action is selected in Control action designation (page 10).
Derivative time setting
Mode to set the derivative time.
Setting value Setting range: 0 to 3600s
[Factory adjusted as 50s]
Setting the value to 0 disables the function.
This display is not available when the ON/OFF action is
selected in Control action designation (page 10).
Proportional cycle setting Mode to set the proportional cycle
Setting value
Setting range: 1 to 120s
[Factory adjusted as 30s to Relay contact output type
and 3s to Non-contact voltage output type]
This display is not available when the ON/OFF action is
selected in Control action designation (page 10).
This setting item is not available to Current output type.
With the Relay contact output type, if the proportional cycle time
is decreased, the frequency of the relay action increases, and
the life of the relay contact is shortened.
Manual reset setting
Mode to set the reset value to correct the offset
Setting value
(Deviation between SV and PV when equilibrium status).
Setting range: proportional band converted value
[However, in the range, –199.9 to 999.9°C (°F)
]
[Factory adjusted as 0.0°C]
This display is indicated only when PD action is designated in
the Control action designation (page 10).
Manual reset setting method:
When SV>PV, set the positive + value (SV–PV).
When SV
