L93 Overheat Early Warning Level
When the temperature reaches the overheat early warning level that is n ° C below the trip level, the
inverter issues an overheat early warning signal. L93 specifies the n ° C. The early warning signal OH
is assigned to a general-purpose, programmable output terminal by setting E20 to E24 and E27 to
“28”.
- Data setting range: 1 to 20 (deg)

When any of the following conditions is
met, the
OH
signal is turned ON.
- The heat sink temperature is higher
than "Heat sink overheat trip
temperature - L93 setting."
- The inverter inside temperature is
higher than "Internal overheat trip
temperature - L93 setting."
- The IGBT junction temperature is
higher than "Inverter overload trip
temperature - L93 setting."
When all of the following conditions
are met, the
OH
signal is turned OFF.
- The heat sink temperature is lower
than "Heat sink overheat trip
temperature - L93 setting - 3 ° C."
- The inverter inside temperature is
lower than "Internal overheat trip
temperature - L93 setting - 3 ° C."
- The IGBT junction temperature is
lower than "Inverter overload trip
temperature - L93 setting - 3 ° C."
