Applications of D Registers (for UT75A)
14
14.4 UT75A D Registers
Current SP Group and PID Group (D2101 to D2200)
Register
No.
Description Range and meaning of value
D2101 SP_L1_* Loop-1 target setpoint
0.0 to 100.0% of PV input range (EU) (Setting
range: SPL to SPH)
D2102 SUB_*
Loop-1 sub-target setpoint (in Two-
position two-level control)
Set the offset from SP.
-100.0 to 100.0% of PV input range span (EUS)
D2103 PIDN_L1_* Loop-1 PID number selection
Set a PID group number to use.
1 to 8 (Depends on the PIDG. setting.)
D2104 A1_L1_* Loop-1 alarm-1 setpoint
Set a display value of setpoint of PV alarm, SP
alarm, deviation alarm, output alarm, or velocity
alarm.
-19999 to 30000 (Set a value within the input
range.)
Decimal point position depends on the input type.
D2105 A2_L1_* Loop-1 alarm-2 setpoint
D2106
A3_L1_*
Loop-1 alarm-3 setpoint
D2107 A4_L1_* Loop-1 alarm-4 setpoint
D2108 A5_L1_* Loop-1 alarm-5 setpoint
D2109 A6_L1_* Loop-1 alarm-6 setpoint
D2110 A7_L1_* Loop-1 alarm-7 setpoint
D2111 A8_L1_* Loop-1 alarm-8 setpoint
D2112 to D2113
D2114 P_L1_*
Proportional band
Heating-side proportional band (in
Heating/cooling control)
0.0 to 999.9%
When 0.0 is set, it operates as 0.1.
Heating-side ON/OFF control applies when 0.0 in
Heating/cooling control
D2115 I_L1_*
Integral time
Heating-side integral time (in Heating/
cooling control)
0: OFF (Disable)
1 to 6000 s
D2116 D_L1_*
Derivative time
Heating-side derivative time (in
Heating/cooling control)
0: OFF (Disable)
1 to 6000 s
D2117 OH_L1_*
Control output high limit
Heating-side control output high limit (in
Heating/cooling control)
-4.9 to 105.0%, (OL<OH)
In Heating/cooling control: 0.1 to 105.0% (OL<OH)
D2118 OL_L1_*
Control output low limit
Heating-side control output low limit (in
Heating/cooling control)
-5.0 to 104.9%, (OL<OH), SD: Tight shut
In Heating/cooling control: 0.0 to 104.9% (OL<OH)
D2119 MR_L1_* Manual reset
Enabled when integral time is OFF.
The manual reset value equals the output value
when PV = SP.
-5.0 to 105.0%
D2120 HYS_L1_*
Hysteresis (in ON/OFF control,
Position proportional control, or Two-
position two-level control)
Heating-side ON/OFF control
hysteresis (in Heating/cooling control)
In ON/OFF control or Two-position two-level control:
0.0 to 100.0% of PV input range span (EUS)
In Heating/cooling control or Position proportional
control: 0.0 to 100.0%
D2121 SU.HY_L1_*
Sub-hysteresis (in Two-position two-
level control)
0.0 to 100.0% of PV input range span (EUS)
D2122 HY.UP_L1_*
Upper-side hysteresis (in ON/OFF
control)
0.0 to 100.0% of PV input range span (EUS)
D2123 HY.LO_L1_*
Lower-side hysteresis (in ON/OFF
control)
D2124 DR_L1_* Direct/reverse action switch
0: RVS (Reverse action)
1: DIR (Direct action)
D2125
SU.DR_*
Sub-direct/reverse action switch (in
Two-position two-level control)
D2126 Pc_L1_* Cooling-side proportional band
0.0 to 999.9%
(Cooling-side ON/OFF control applies when 0.0 in
Heating/cooling control)
D2127 Ic_L1_* Cooling-side integral time
0: OFF (Disable)
1 to 6000 s
D2128 Dc_L1_* Cooling-side derivative time
0: OFF (Disable)
1 to 6000 s
D2129 OHc_L1_* Cooling-side control output high limit 0.1 to 105.0%, (OLc<OHc)
* 1 to 20 is written in D2101 to D2112 and D2151 to D2163.
1 to 16, or R (currently used group number) is written in D2114 to D2135 and D2164 to
D2185.
