ch2: 02B3H (691)
Proportional band limiter (high): Use to set the high limit value of Proportional band.
Proportional band limiter (low): Use to set the low limit value of Proportional band.
(However, Proportional band limiter (high)

Proportional band limiter (low))
Attribute:
R/W
Digits:
7 digits
Number of data:
2 (Data of each channel)
Data range:
RTD input: 0 (0.0, 0.00) to Input span (Unit:

C)
(Varies with the setting of the decimal point position.
However, even if "3: Three decimal places" is set, the maximum
settable decimal places are 2.)
Voltage (V) input: 0.00 to 300.00 % of input span
0 (0.0, 0.00): ON/OFF action
Factory set value:
Proportional band limiter (high): RTD input: Input span
Voltage (V) input: 300.00
Proportional band limiter (low): RTD input: 0.00
Voltage (V) input: 0.00
Related parameters:
PID/AT transfer (P. 9-13), Proportional band (P. 9-22),
Decimal point position (P. 9-46)
Function:
The Proportional band range is restricted while the Autotuning (AT) function is
being executed.
Integral time limiter (high)
RKC communication
identifier I6

register address ch1: 02B6H (694)
ch2: 02B7H (695)
Integral time limiter (low)
RKC communication
identifier I7
Modbus
register address ch1: 02BAH (698)
ch2: 02BBH (699)
Integral time limiter (high): Use to set the high limit value of Integral time.
Integral time limiter (low): Use to set the low limit value of Integral time.
(However, Integral time limiter (high)

Integral time limiter (low))
Attribute:
R/W
Digits:
7 digits
Number of data:
2 (Data of each channel)
Data range:
0.0 to 3000.0 seconds (0.0: PD action)
Factory set value:
Integral time limiter (high): 3000.0
Integral time limiter (low): 0.0
Related parameters:
PID/AT transfer (P. 9-13), Integral time (P. 9-23),
Integral/Derivative time decimal point position
(P. 9-68)
Function:
The Integral time range is restricted while the Autotuning (AT) function is being
executed.
If the Autotuning (AT) function is executed when the Integral time limiter (high) is set at “0.0,” P
and D values suitable to PD control are computed.
