OUT-31–35 Relay1–5
When the code value is set to ‘8 (FAN Warning)’, the fan error signal is output
and operation continues. However, when the inverter’s inside temperature
rises above a certain level, output is blocked due to activation of overheat
protection.
6.3.2
Low Voltage Fault Trip
When inverter input power is lost and the internal DC link voltage drops below a certain voltage
level, the inverter stops output and a low voltage trip occurs.

Description
PRT-81
LVT Delay
If the code value is set to ‘11 (Low Voltage)’, the inverter stops the output first when a
low voltage trip condition occurs, then a fault trip occurs after the low voltage trip
decision time elapses. The warning signal for a low voltage fault trip can be provided
using the multi-function output or a relay. However, the low voltage trip delay time
(LVT Delay time) does not apply to warning signals.
