35
*1 To monitor or change during control, set a value for both the setting value and the device indirect specification or only the device indirect
specification.
*2 Set a value larger than the scan time. Also set a value so that the sampling time (TS) becomes smaller than the control output cycle.
Control Parameter Set a value for at least one of the setting value and the device
indirect specification.
*1
■Proportional Gain (KP)
• Set 100% for the setting value.
• Set D200 for the device.
■Integral Time (TI)
• Set 200  100ms for the setting value.
• Set D203 for the device.
■Derivative Time (TD)
• Set 300  100ms for the setting value.
• Set D204 for the device.
Set a value for at least one of the setting value and the device
indirect specification.
*1
■Heating Proportional Gain (KPh)
• Set 100% for the setting value.
• Set D201 for the device.
■Cooling Proportional Gain (KPc)
• Set 200% for the setting value.
• Set D202 for the device.
■Integral Time (TI)
• Set 300% for the setting value.
• Set D203 for the device.
■Derivative Time (TD)
• Set 400  100ms for the setting value.
• Set D204 for the device.
Sampling Time (Ts) Set a value for at least one of the setting value and the device
indirect specification.
*1
• Set 10  10ms for the setting value.
*2
• Set D300 for the device.
Set a value for at least one of the setting value and the device
indirect specification.
*1
•Set 10  10ms for the setting value.
• Set D300 for the device.
Operation Cycle Set a value for at least one of the setting value and the device
indirect specification.
*1
■Control Output Cycle
• Set 50  100ms for the setting value.
*2
• Set D301 for the device.
Set a value for at least one of the setting value and the device
indirect specification.
*1
■Heating Control Output Cycle
•Set 50  100ms for the setting value.
• Set D302 for the device.
■Cooling Control Output Cycle
•Set 50  100ms for the setting value.
• Set D303 for the device.
Control Output Set a value for at least one of "Output Value (MV)" and
"Control Output".
• Set Y1 for "Control Output".
Set a value for at least one of "Output Value (MV)" and
"Control Output".
• Set Y1 for "Control Output".
• Set Y2 for "Control Output (for Cooling Control)".
PID Control Execution
Command
Always set a value for this item.
•Set X0.
Always set a value for this item.
•Set X0.
To Use or Not to Use Auto-
tuning
When the set device is turned on, auto tuning becomes
available. When the set device is turned off, or no value is set
for the device, operation is performed without auto tuning.
• This item is not set in this example.
When the set device is turned on, auto tuning becomes
available. When the set device is turned off, or no value is set
for the device, operation is performed without auto tuning.
• This item is not set in this example.
PID Control Execution Status Set this item when monitoring the PID control execution
status.
•Set M0.
Set this item when monitoring the PID control execution
status.
•Set M0.
Auto-tuning Execution Status Set this item when monitoring the auto tuning execution
status.
• This item is not set in this example.
Set this item when monitoring the auto tuning execution
status.
• This item is not set in this example.
PID Control Function Error
Display
Set this item when monitoring the error status during PID
control.
•Set Y0.
Set this item when monitoring the error status during PID
control.
•Set Y0.
