CH1 Lower limit output limiter
Set the lower limit value for actually outputting the manipulated value (MV) calculated by the PID operation to an external
device.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory area name
CH Lower limit output limiter
CH Lower limit output limiter (in the Q compatible mode)
■Setting range
The setting range is -50 to 1050 (-5.0 to 105.0%).
Set values so that the lower limit output limiter value is smaller than the upper limit output limiter value.
When the lower limit output limiter value is equal to or greater than the upper limit output limiter value, CH Upper/lower limit
output limiter setting error (error code: 1A0H) occurs.
When a value out of the setting value is set, an out of setting range error (error code: 1950H) occurs. When an error has
occurred, the following operations will be executed:
• 'Error flag' (X2) turns ON.
• An error code is stored in 'Latest error code' (Un\G0).
■Two-position control
In the two-position control, this setting is disabled.
■Manual control
In the manual control, this setting is enabled.
When an output to an external device exceeds the lower limit output limiter value, the manipulated value (MV) of the manual
control is fixed (clipped) to the set lower limit output limiter value.
■Default value
The default value is 0 (0.0%).
