9
Action setting: (s3)+1
■
Direction (direct action/reverse action): Bit 0 of (s3)+1
Setting range: Off = Direct action, On = Reverse action
Select the direction of PID control, direction action or reverse action.
• Auto tuning (limit cycle method)
The PID control direction must be set.
• Auto tuning (step response method)
At completion of auto tuning executed in whichever mode, direct action or reverse action, setting is made automatically.
[Direct action (bit 0 of (s3)+1 = Off)]
[Reverse action (bit 0 of (s3)+1 = On)]
■
Alarm setting (input variation, output variation): Bit 1 and bit 2 of (s3)+1
Setting range: Off = Alarm disabled, On = Alarm enabled
The input and output variation amounts can be checked. The check result can be checked in (s3)+24. (
output flag: (s3)+24)
• Input variation (bit 1 of (s3)+1)
To use the input variation alarm, the following bit needs to be on and the values need to be set to the following devices.
• Output variation (bit 2 of (s3)+1)
To use the output variation alarm, the following bits need to be on and the values need to be set to the following devices.
