„ Make setting under PID control
To enable PID control, you need to set function code J01 to 1 or 2.
Under the PID control, the items that can be set 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, you may access manual speed commands (frequency command) with
and keys; if it
is set to any other value, you may access the PID process command with those keys.
Refer to the FRENIC-Eco User's Manual for details on the PID control.
„ Setting the PID process command with and keys
(1) Set function code J02 to "0: Keypad operation."
(2) Set the LED monitor to something other than the speed monitor (E43 = 0) while the keypad is in Running
Mode. You cannot modify the PID process command using the / key while the keypad is in
Programming Mode or Alarm Mode. To enable the modification of the PID process command by the
/
key, first switch to Running Mode.
(3) Press the / key to have the PID process command displayed. The lowest digit will blink together
with the dot on the LED monitor.
Figure 3.7 PID Process Commands
(4) To change the PID process command, press the / key again. The PID process command you have
specified will be automatically saved into the inverter’s internal memory. It is kept there even if you
temporarily switch to another means of specifying the PID process command and then go back to the means
of specifying the PID process command via the keypad. Also, it is kept there even while the inverter is
powered OFF, and will be used as the initial PID process command next time the inverter is powered ON.
