CH1 Manual output setting
This buffer memory area is used to set the manipulated value (MV) in the MAN mode.
Even though writing of data is executed during control in the AUTO mode, the setting values do not change.
■Buffer memory address
The following table shows the buffer memory address of this area.
Buffer memory name
CH Manual output setting
CH Manual output setting (If using FX3 allocation mode)
■How to shift the mode
Change the mode with the following buffer memory area.
• 'CH1 AUTO/MAN mode shift' (Un\G518) (Page 149 CH1 AUTO/MAN mode shift)
■Setting range
-50 to 1050 (-5.0 to 105.0%)
■Enabling the settings
Check that "CH1 event (Un\G429)" in the Manual output settings is b13 before writing.
A value that has been written while MAN mode shift completion flag is OFF will be replaced with the manipulated value (MV)
that the system calculated using the PID operation.
■Default value
The default value is -50 (-5.0%).
CH1 Cooling upper limit output limiter
Set the upper limit value for actually outputting the manipulated value for cooling (MVc) calculated by the cooling and heating
PID operation to an external device. In the auto tuning, this setting is ignored.
■Buffer memory address
The following table shows the buffer memory address of this area.
Buffer memory name
CH Cooling upper limit output limiter
CH Cooling upper limit output limiter (If using FX3 allocation mode)
■Setting range
This is 0 to 1050 (0.0 to 105.0%).
In the heating-cooling PID control, the lower limit value is not used. When 'CH1 Lower limit output limiter'
(Un\G509) is set to a value other than 0, an out of setting range error (error code: 1950H) occurs.
■Two-position control
In the two-position control, this setting is disabled.
■Default value
The default value is 1000 (100.0%).
