4-109
03-0X =16: PID control disable.
Note: The frequency will depend on parameter 00-05 (reference frequency) to determine the source of
frequency input. Refer to the descriptions of parameter 00-05 and 00-06 for details.
03-0X =17: Fault reset
The output becomes active when the inverter trips on a fault. Upon an inverter fault the inverter output will
turn off (base block) and the keypad displays the dedicated fault message.
When fault occurs, the following actions can be used to reset the fault:
1. Program one of the multi-function digital inputs (03-00 to 03-05) to 17 (reset fault) and active input.*
2. Press the reset key of the digital operator (RESET).*
3. Recycle power to the inverter. Important Note: If a run command is active during power-up, the
inverter will start running automatically.
* To reset an active fault the run command has to be removed.
03-0X =19: Speed Search 1 (from the maximum frequency).
03-0X =34: Speed Search 2 (from the frequency command).
Refer to the "speed search" function in the parameter group 7 (start/ stop control function).
03-0X =20: Energy saving enabled
Manual energy savings function is set with parameters 11-12 and 11-18.
For the manual energy saving operation refer to Figure 4.3.78.
03-0X =21: PID integral reset
03-0X =25: External fault
Activating the external fault input will turn off the inverter output and the motor will coast to a stop. The
keypad displays the external fault message “EFn Ext. Fault (Sn)”, where n is the input terminal number.
03-0X =27: Local / Remote selection.
Switch the inverter frequency reference source between Local (keypad) or Remote (control circuit
terminals or RS485). Use parameter 00-05 (Main frequency command source selection) and 00-02 (Run
command selection) to select the input source. When PID is enabled (10-03=XXX1), parameter 10-00
(target value source) is performed. If 23-00=1, make sure the setting value of parameter 23-04. If 23-00=2,
make sure the setting value of parameter 23-59 and 00-02.
Note: In 3-wire operation terminal S1 and S2 are reserved for run/stop operation and the Local / Remote
function can only be set to digital input terminals S3 to S6 (03-02 to 03-05).
Note: To switch between local and remote the inverter has to be stopped.
Input Mode Frequency Reference / Run/Stop Command Source
ON Local
- Frequency reference and Run-Stop from keypad.
- LEDs SEQ and REF are off.
- When PID is enabled, REF indicator OFF presents PID target value is
set by the keypad.
OFF Remote
- Frequency reference source selected by parameter 00-05 and
Run-Stop source selected by parameter 00-02.
- LEDs SEQ and REF are on.
- When PID is enabled, REF indicator ON presents PID target value is
set by the control terminal AI1.
