Register
No.
Description Range and meaning of value
D5001 CTLM Control mode
1: SGL (Single-loop control)
2: CAS1 (Cascade primary-loop control)
3: CAS2 (Cascade secondary-loop control)
4: CAS (Cascade control)
5: BUM (Loop control for backup)
6: PVSW (Loop control with PV switching)
7: PVSEL (Loop control with PV auto-selector)
8: PVHD (Loop control with PV-hold function)
11: Dual-loop control
* When using the ladder program, the control mode
cannot be changed.

3: 2P2L (Two-position two-level control)
4: H/C (Heating/cooling control)
5: S-PI (Sample PI control)
6: BATCH (Batch PID control)
7: FFPID (Feedforward control)
D5004 CNT_L2 Loop-2 control type
0: PID (PID control)
1: ONOF (ON/OFF control (1 point of hysteresis))
2: ONOF2 (ON/OFF control (2 points of hysteresis))

Loop-2 PID control mode
D5007 SPGR. Number of SP groups
Set a number of SP groups to use.
1 to 20
D5008
D5009
ALNO._L1
Loop-1 number of alarms 1 to 8

constants to be selected for each SP group.
If set to “Zone PID selection,” automatically selects
PID constants according to the range set in the
Reference point.
