6.4 UT55A/UT52A/UP55A D Registers
Loop-1 Control Action-related Setting (D3501 to D3600)
Register
No.
Description Range and meaning of value
D3501 SC_L1 Super function
0: OFF (Disable)
1: Overshoot suppressing function (normal mode)
2: Hunting suppressing function (stable mode)
Enables to answer the wider characteristic
changes compared with response mode.
3: Hunting suppressing function (response mode)
Enables quick follow-up and short converging
time of PV for the changed SP.
4: Overshoot suppressing function (strong
suppressing mode)
Note: Setpoints 2 and 3 must be used in PID control
or PI control. Disabled in the following controls:
1) ON/OFF control, 2) PD control, 3) P control,
4) Heating/cooling control
Do not use the function for the control
processes with response such as flow or
pressure control.
