Minor Alarm Selection

When various error states are detected, this function enables continuation of operation without tripping
the inverter if they are minor errors. When this is selected, the alarm becomes a minor alarm. The con-
tents of the minor alarm can be selected at Light Alarm Selection 1 (H81)/Light Alarm Selection 2
(H82).

 Precautions for Correct Use
Overheat protection (alarm code: 11, 13, 46) protects by overheat protection (alarm code: 19) of
the inverter that cannot ultimately be turned into a minor alarm. When Motor Electronic Thermal
(alarm code: 17, 18), Braking Resistor Thermal (alarm code: 16) and External Alarm (alarm code:
12) are turned into minor alarms, there is the risk of motors and other external devices burning de-
pending on setting and method of use.
 Alarms That Can Be Changed to Minor Alarms
The following alarms can be changed to minor alarms.

Overview
The cooling fin temperature has risen to the trip lev-
el.
An error has occurred in a peripheral equipment, and
the external trip "EXT" signal has turned ON.
The internal temperature of the inverter has risen ab-
normally.
The temperature of the inrush current prevention re-
sistor has risen abnormally due to frequently turning
the power supply ON/OFF.
The estimated temperature of the braking resistor
coil has risen above the permissible temperature.
