Low Voltage Fault Trip
When the inverters DC link voltage drops below the low voltage trip level, the inverter shuts off the
output and a low voltage trip
occurs

Low Voltage Fault Setting Details
Code Description
Pr.81 LVT Delay When a low voltage trip occurs, the inverter shuts off the output. The delay
time applies to the fault indication. The multi-function output terminals
(Relay1 and Q1) can be set to provide a low voltage trip output. Set
parameters OU.31 and/or OU.33 to 11 (Low Voltage). The terminals activate
(close) when a low voltage trip occurs. The low voltage trip delay time (LVT
Delay time) does not apply to these outputs.
Output Block by Multi-Function Terminal
Set one of the digital input terminals Px to 5 (Bx). When activated, the output of the inverter is
blocked and the motor coasts to a stop. The digital input terminal can be set to NC or NO by
changing the applicable bit at parameter In.87.

Output Block by Multi-Function Terminal Setting Details
Code Description
In.65-71 Px Define When a multi-function input terminal is set to 5 (BX) and is activated during
operation, the inverter shuts off the output and ‘BX’ is displayed on the keypad.
While ‘BX’ is displayed on the keypad, the inverter’s operation information
including the operating frequency, current and status at the time of BX signal can
be viewed by pressing the ENT key. The inverter will resume operation when the
BX terminal is de-activated and operation command is re-applied.
