Overtorque Detection 1 (N.O.)
or Overtorque Detection 2 (N.O.)
Note The overtorque detection is cleared when the current drops about 5% of the Inverter's rated cur-
rent (or the motor's rated torque).

L8-01 DB Resistor Prot
Note This parameter cannot be changed during operation.
Setting
0 Disabled. (Select 0 when a braking resistor isn't being used or a Braking Resistor Unit is being
used.)
1 Enabled. (Protects the braking resistor from overheating.)

L8-02 OH Pre-Alarm Lvl
L8-03 OH Pre-Alarm Sel 0 to 3
Note These parameters cannot be changed during operation.
Parameter L8-02 specifies the detection temperature in S C for the Inverter overheat (OH) pre-alarm
function. An overheat pre-alarm occurs when the temperature of the cooling fins reaches this level.
Parameter L8-03 specifies the processing that will be performed when an overheat pre-alarm occurs.
