Overcurrent pre-alarm ■ON' during overcurrent stall protection operation
■ON' when the output current reaches the setting value level of
51 L 1 in C r . P r , or 5 b L 2 in C r . F B
when using fundamental parameters #Z
(Same level as the blinking t alarm on the operating panel
LED)
I B Inverter overload pre-alarm 'ON' when the cumulative trip amount of D L I n (inverter
overload trip) is 50% or more of the trip level.
I B Motor overload pre-alarm ■ON' when the cumulative trip amount of O L f i t (motor
overload trip) is 50% or more of the trip level.
B O Overheat pre-alarm ■ON' when heatsink temperature is 84°C or higher
Once 'ON', turns 'OFF' again when temperature drops to 80“C or
less
B B Overvoltage pre-alarm ■ON' during overvoltage limit operation (OP stalO of DC main
circuit voltage.
200V system: approx. 370Vdc
400V system: approx. 740Vdc
(Same level as the blinking p alarm on the operating panel
LED)
B H Undervoltage alarm ■ON' when main circuit DC voltage is below the following levels:
200V system: approx. 200Vdc
400V system: approx. 380Vdc
B B Undercurrent alarm ■ON' when output current is lower than the setting value of
L L P C in C n . P r and continues for longer than the
time set in L L P b •
B B Overtorque alarm ■ON" when the torque current exceeds the setting value of
D b L in B r . P r .
3 0 Braking resistor overload pre­
alarm ■ON' when the O L r cumulative trip amount is 50% or more
of the trip level.
* The checking conditions for the following alarm outputs differ from each other as indicated:
Undervoltage alarm: Checked while running.
Undercurrent alarm: Checked during run command.
Overtorque alarm ; Constantly checked.
Note) During reset, all status alarms will enter the OFF state regardless of the operating conditions.
