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 the
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), you may access manual feed commands (Set
frequency) with the
mands with those keys.
Refer to the FRENIC-Mini User's Manual (MEH446), Chapter 4, Section 4.8 "PID Frequency
Command Generator" for details on the PID control.
Setting the PID process command with the built-in potentiometer
(1) Set function code E60 to "3: PID process command 1."
(2) Set function code J02 to "1: PID process command 1. "
Setting the PID process command with the
(1) Set function code J02 to "0: Keypad operation."
(2) Set the LED monitor to the setting other than the speed monitor (E43 = 0) in Running mode.
This setting is possible only in Running mode.

mand. Once the PID process command is modified, it will be saved internally. Even if the inverter
is switched to any other PID process command entry and then returned to the keypad entry, the
setting will be retained.
Further, even turning off the inverter will automatically save the setting into the non-volatile mem-
ory. At the next time when the inverter is turned on, the setting will become the default PID process
command.
Even if the PID process command is selected ((SS4) = ON) in the multistep frequency, it is still
possible to set the process command using the keypad.
When function code J02 data has been set to any value except 0, pressing the
plays the PID process command currently selected (setting is not possible).
When the PID process command is displayed, the decimal point next to the lowest digit on the
LED display blinks to discriminate it from the regular frequency setting.
Setting up the set frequency with the
To set the set frequency with the
following conditions:
- Set function code F01 to "0: Keypad operation."
- Select frequency command 1 (Frequency settings from communications link: Disabled, and
Multistep frequency settings: Disabled) as manual speed command.
- Set the LED monitor to the speed monitor in Running mode.
The above setting is impossible in any operation mode except Running mode.
The setting procedure is the same as that for usual frequency setting.
