T: Auxiliary reference−50%: The auxiliary reference value subtracts the bias equal to 50% of the
auxiliary reference full range value. The main reference value is disable at this calculation formula.
3: Main reference + auxiliary reference−50%: The auxiliary reference value subtracts the bias equal to
50% of the auxiliary reference full range value and then superimposes on the main reference.

PT.0T Analog feedback close loop control main reference channel
PT.03 Analog feedback close loop control auxiliary reference channel
Analog feedback close loop control main reference and auxiliary
PT.04
In analog feedback close loop system, digital voltage setting, analog and pulse can be set as main
reference channel; analog and pulse can be set as auxiliary reference channel.
The parameter PT.0T is used to set the main reference channel of process close loop control:
0: P8.00 setting
The parameter PT.03 is used to set the auxiliary reference channel of process close loop control:
0: None
The parameter PT.04 is used to set the main reference and auxiliary reference calculation formula of
process close loop control:
0: Main + auxiliary
4: Maximum
The main reference and auxiliary reference calculation for close loop to the same as the main reference
and auxiliary reference calculation function for open loop. For details, refer to the description of PT.0T.
