3.3 Running Mode
3-12
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 differ depending
upon the current LED monitor setting. If the LED monitor is set to the speed monitor, the item accessible is
the primary frequency command; if it is set to any other data, it is the PID dancer position command.
Setting the PID dancer position command with the
and keys
(1) Set function code J02 to "0" (
and keys on keypad).
(2) Set the LED monitor to something other than the speed monitor (E43=0) when the inverter is in
Running mode. When the keypad is in Programming or Alarm mode, you cannot modify the PID
command (dancer position) with the
/ key. To enable the PID dancer position command to be
modified with the
/ key, first switch to Running mode.
(3) Press the
/ key to display the PID dancer position command. The lowest digit and its decimal
point blink on the LED monitor.
(4)
To change the PID dancer position command, press the / key again. The command you have
specified will be automatically saved into the inverter’s internal memory as function code J57 data. It
is retained even if you temporarily switch to another PID command source and then go back to the
via-keypad PID command. Furthermore, you can directly configure the command with function code
J57.
• Even if multi-frequency is selected as a PID command (SS4 or SS8 = 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, while you cannot change the
setting.
• On the LED monitor, the decimal point of the lowest digit is used to discriminate the PID
related data from the frequency command. The decimal point blinks or lights when a PID
command or PID feedback amount is displayed, respectively.
