PID control mode 0: Standard PID control (with output bump at SP change)
1: Fixed Point control (without output bump at SP change)
Choose “Fixed Point Control” when controlling pressure or flow rate. 0
Zone PID selection 0: SP selection
1: Zone PID 0
(C.MD)
Ramp-rate time unit
setting 0: hour, 1: minute
Time unit of setpoint ramp-up (UPR) and setpoint
ramp-down (DNR) 1
(TMU)
Protocol selection 0
Baud rate 0: 600, 1: 1200, 2: 2400, 3: 4800, 4: 9600 (bps) 4
Parity 0: None
1: Even
2: Odd
1
Stop bit 1, 2 1
Data length 7, 8;
Fixed at 7, when the P.SL parameter is set to MODBUS (ASCII).
Fixed at 8, when the P.SL parameter is set to MODBUS (RTU)
or Ladder Communication. 8
0: PC link communication
1: PC link communication (with sum check)
2: Ladder communication
3: Coordinated master station
4: Coordinated slave station
7: MODBUS (ASCII) 8: MODBUS (RTU)

Name of Parameter Setting Range and Description Initial Value User Setting
Target Item
in CD-ROM
AUTO (0) Anti-reset windup
(Excess integration
prevention) AUTO (0), 50.0 to 200.0%
Used when the control output travels up to 100% or down
to 0% and stays at this point.
The larger SP, the sooner PID computation
(integral computation) stops.
(AR)
(ZON)
Address 1 to 99
However, the maximum number of stations connectable
is 31. 1
