The sleep operation start level is set by
output frequency.
The sleep operation starts when [A156] or
a lower value persists for the duration of
this setting.
Outputs "Over deviation for PID control
[OD] (04)" when PID deviation equals or is
greater than this setting. Set in units of %,
with the maximum frequency being 100%.
Sets the point at which the PID feedback
comparison signal is turned OFF.
Sets the point at which the PID feedback
comparison signal is turned ON.
Disable PID [PID]:
Turn this signal ON to disable PID
calculation and enter normal frequency
operation mode.
PID integration reset [PIDC]:
Turn this signal ON to reset the integral
value of PID control to 0.
Over deviation for PID control [OD]:
This signal turns ON when the PID
deviation equals or exceeds the [C044]
setting.
PID feedback comparison [FBV]:
This signal turns ON when the PID
feedback falls outside the setting range.
