6.SETTING AND ADJUSTMENT OF READING

6-1-4. Operation select
Depending on the option selected in this field, the system’s STAR/STOP is controlled
either by internal (touch-panel key) or external input. Auto-resume function (restore
states and resume operation after a power failure) can only be enabled when internal
input is selected. If “EXTERNAL ENTRY” is selected in this field, the RUNNING
control signal is used to start/stop the operation: touch panel is disabled. If “KEY
POW.C. ON” or “KEY POW.C. OFF” is selected,
and key on the
upper pane of the comparison and message screen controls start/stop of the operation
(control signal RUNNING is ignored).
Operation
6-1-5. Rated belt speed
This parameter specifies the rated value of the belt speed. If “Analog 1Ch. mode” or
“Analog 2 Ch. mode” is selected in [SPEED ENTRY SELECT], the rated belt speed is
set to the full-span value of the analog input. If “No” is selected in [SPEED ENTRY
SELECT], the value specified in this field defines the rated belt speed.
Operation
6-1-6. Dead band
PID control is performed only when the absolute value of CTRL.DEVIATION is
greater than dead band. If this is not the case, the CONTROL RATE of the previous
instance will be maintained. If frequent ON/OFF transitions are expected while
controlling the system, proper dead band setting is effective to prevent output
chattering and noise interferences.
If the value for the dead band is set to 0.0, PID control is performed at all times.
