Features
Startup tuning eliminates time required for conventional
autotuning as it calculates optimum PID values by temperature
characteristics at start up.
It is useful in applications which require a long time for
conventional autotuning.
The timing of activation of start-up tuning can be selected from
at power-up, at setpoint change, and at power-up/setpoint
change. It is also settable to Only-once or always-ON.

Calculates optimum PID values to stabilize
control faster than ever
The improved autotuning algorithm calculates optimum PID
values that shortens the time to reach stable control at the set
value as well as eliminating overshoot/undershoot.
The new PID algorithm also suppress overshoot/undershoot
against external disturbance.

Easy Fine tuning with 6-level of control
response adjustment
After the PID values have been autotuned, the Fine tuning (FT)
function allows the operator to adjust the control response speed
with a 6-level adjustment parameter (-3 to +3) without changing
PID value.

Startup tuning
The RB series has a standard loader port to connect to a PC
USB port via COM-K2 (USB communication converter).
Using Win-UCI software on the PC, parameter settings can be
easily saved on the PC in CSV format, and the same parameter
settings are easily copied to other controllers.
• Startup tuning function can be set ON/OFF.
• Heater power needs to be turned on simultaneously with or before turning on power to the
temperature controller.
• If startup tuning does not calculate suitable PID values due to characteristics of application,
use Autotuning function.

Easy parameter setup via USB loader port
A communication protocol converter becomes a Master Unit to
PLC, and automatically stores temperature data into registers in
a PLC. This enables easy handling of temperature control
system to the exiting PLC system is available.
• The power to COM-K2 is supplied
from the PC via the USB port so
no power supply is necessary.
