(Sn)", indicating the inverter output is turned off (n indicates the digital input number 1 – 8). Upon removing the
base block signal, the motor is stopped or will coast to a stop and the inverter will remains in the stop condition.
During acceleration: When an external base block command is activated, the keypad displays "BBn BaseBlock
(Sn)", indicating the inverter output is turned off (n indicates the digital input number 1 – 8). Upon removing the
base block signal, the motor will run at the frequency reference. If speed seach from frequency reference is active
the inverter output frequency starts from the frequency reference and searches for the coasting motor speed and
continue to operate. If speed search is not active the output frequency starts at 0Hz.

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.
