Settings under PID dancer control
To enable the PID dancer control, you need to set function code J01 to "3."
Under the PID control, the items that can be specified or checked with
and keys are different
from those under the 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 data, it is the PID dancer position command.

Refer to the FRENIC-Multi User's Manual for the details of the PID control.
Setting the PID dancer position command with the
and keys
(1) Set function code J02 to "0:
/ 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 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 of the
displayed command and its decimal point blink.
(4) To change the 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), you still can
set the PID dancer position command using the keypad.
• When function code J02 is set to any value other than "0," pressing the / ke
y
displays, on the 7-segment LED monitor, the PID command currently selected, while you
cannot change the setting.
• On the 7-segment LED monitor, the decimal point of the lowest digit is used to
characterize what is displayed. The decimal point of the lowest digit blinks when a PID
command is displayed; the decimal point lights when a PID feedback amount is
displayed.
