3.3 Running Mode
3-12
[ 2 ] Settings under PID dancer control
To enable the PID dancer control, you need to set the J01 data to “3.”
Under the PID control, the items that can be specified or checked with and keys are different from those
under regular frequency control, depending upon the current LED monitor setting.
If the LED monitor is set to the speed monitor (E43 = 0), the item accessible is the primary frequency command; if
it is set to any other, the item is the PID dancer position set point.
Setting the PID dancer position set point with the and keys
(1) Set function code J02 to “0” ( / keys on keypad).
(2) Set the LED monitor to other than the speed monitor (E43=0) in keypad Running mode. When the keypad is
in Programming or Alarm mode, you cannot modify the PID dancer position set point with the / key.
To enable PID commands using the / keys, switch to running mode.
(3) Press the / key to display the PID dancer position set point. The lowest digit and its decimal point
blink on the LED monitor.
(4) To change the PID dancer position set point, press the / key again. The set PID command is saved
internally as function code J57, and after switching to another PID command setting method, commands are
saved even after returning to the PID command with the keypad. Furthermore, you can directly configure the
command with function code J57.
• Even if multistep frequency is selected as a PID command (
PID-SS1
or
PID-SS2
= ON), it is possible
to set a PID command using the keypad.
• When function code J02 is set to any value other than “0,” pressing the / key displays, on the
LED monitor, the PID command currently selected, but does not allow any change.
• On the LED monitor, the decimal point of the lowest digit is used to discriminate the PID related data
from the reference command. The decimal point blinks or lights when a PID command or PID feedback
amount is displayed, respectively.
