[Description]
• This parameter switches the control mode between Auto
and Manual.
• During Manual operation, the decimal point is kept on at
the far right in the SV display section.
• During Manual operation, auto tuning or self tuning is
not done. If the mode is switched to Manual while auto
or self tuning is being done, the tuning is forcibly
terminated. The PID parameter remains the same in such
cases.
• Manual operation output is not limited by MV limit.
• Manual operation can be carried out during standby
operation.
• The operation output set value during Auto/Manual
operation mode and manual mode is stored in non-volatile
memory. It is kept stored even if a power interruption
occurs. When the power is turned on again, the state
before the power interruption is resumed.
• The following table lists the operation output at the time
of switching between Auto and Manual..
