2-position Control Function Set a value for at least one of the setting value and the device
indirect specification.
*1*2
• Set 10 (default value) for the setting value for "Adjustment
Sensitivity (Dead Band)".
Set a value for at least one of the setting value and the device
indirect specification.
*1*2
• Set 10 (default value) for the setting value for "Adjustment
Sensitivity (Dead Band)".
Overlap/Dead Band Setting  Set a value for at least one of the setting value and the device
indirect specification.
*1
Negative setting values are for overlapping, and positive
setting values are for the dead band. Setting 0 disables the
overlap/dead band settings.
• Set D401.

• Set D410 for the device.
■Lower Limit Output Limiter
• Set 0  0.1% for the setting value.
• Set D411 for the device.
Set a value for at least one of the setting value and the device
indirect specification.
*1*2
■Heating Upper Limit Output Limiter
• Set 900  0.1% for the setting value.

• Set D413 for the device.
Output Variation Rate Limiter
Function
Set a value for at least one of the setting value and the device
indirect specification.
*1*2
• The setting value must be 0  0.1%/s (default value).
• Set D414 for the device.
