03-0X =16: PID control disabled.
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 03-07) 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.
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 4.4.88.
03-0X =21: PID integral reset
03-0X =24: PLC Input
It is required to be with the software of
PC Tool Congurator. PLC software program conducts the ladder dia-
gram editing. When the signal output conducts, it will be transmitted to the inverter to be active.
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 =26: 3-wire sequence (forward / reverse command)
When digital input terminals S3~S6 are set to 26, terminals S1 and S2 will be individually changed to run com-
mand and sop command. Refer to the 3-wire operation mode in Figure 4.4.2 for details.
Iif any of the program-
mable inputs (multi function input S3 to S8, parameters 03-02 to 03-07) is set to 26 then that input is used to
enable the 3 wire mode function. 3 wire mode allows to use two buttons to control the inverter: Start and Stop
buttons. In this mode S1 and S2 will automatically be set to S1 = Start button; S2 = Stop button and S7 will be
forward & revers selection, Direction selection. Refer to Figure 4.4.2 for details.
03-0X =27: Local / Remote selection.
Switch the inverter frequency reference source between Local (keypad) or Remote (control circuit terminals or
