(10)CH Upper limit output limiter (address: 105H, 135H, 165H, 195H)
Lower limit output limiter (address: 106H, 136H, 166H, 196H)
Heating upper limit output limiter (address: 105H, 135H, 165H, 195H)
CH Cooling upper limit output limiter (address: 1C5H, 1CAH, 1CFH, 1D4H)
Heating-cooling
In the standard control, set upper limit value/lower limit value for actual output of manipulated value (MV)
calculated by the PID operation to an external device. In the heating-cooling control, set upper limit value of
heating/cooling for actual output of manipulated value for heating (MVh)/manipulated value for cooling (MVc)
calculated by the PID operation to an external device. 105H, 135H, 165H, and 195H are used for heating in the
heating-cooling control. During the auto tuning, setting of Heating upper limit output limiter and Cooling upper
limit output limiter are disabled.
(a) Setting range
The following table lists setting range of each remote buffer memory area.
Remote buffer memory
CH Upper limit output limiter (address:
105H, 135H, 165H, 195H)
CH Lower limit output limiter (address:
106H, 136H, 166H, 196H)
CH Heating upper limit output limiter
(address: 105H, 135H, 165H, 195H)
CH Cooling upper limit output limiter
(address: 1C5H, 1CAH, 1CFH, 1D4H)
● In the standard control, CH Cooling upper limit output limiter (address: 1C5H, 1CAH, 1CFH, 1D4H) is invalid even if it is
set.
● In the heating-cooling control, lower limit value is not used.
(b) Two-position control
The following table lists Enable/Disable of the setting.
Remote buffer memory
CH Upper limit output limiter (address: 105H, 135H, 165H, 195H)
CH Lower limit output limiter (address: 106H, 136H, 166H, 196H)
CH Heating upper limit output limiter (address: 105H, 135H, 165H, 195H)
CH Cooling upper limit output limiter (address: 1C5H, 1CAH, 1CFH, 1D4H)
For details on the two-position control, refer to the following.
Page 149, Section 8.3.3 (1)
Setting range
-50 to 1050 (-5.0% to 105.0%)
0 to 1050 (0.0% to 105.0%)
Remarks
Set the values to lower limit output limiter value < upper limit output
limiter value.
When lower limit output limiter value upper limit output limiter value,
a write data error (error code: 0005H) occurs. In addition, if the
setting is out of the setting value, a write data error (error code:
0004H) occurs. When the error occurs, the following situations occur.
• Error flag (RXA) turns on.
• The error code is stored to Latest error code (RWr0).
If the setting is out of the setting value, a write data error (error code:
0004H) occurs. When the error occurs, the following situations occur.
• Error flag (RXA) turns on.
• The error code is stored to Latest error code (RWr0).
