operation setting
0: None

Torque detection is not operating.
1: OT CmdSpd Warn

Detects over torque and outputs warning only
when the inverter output frequency is the same as the command
frequency.
2: OT Warning

Detects over torque during the operation and outputs
warning.
3: OT CmdSpdTrip

Detects over torque and generates a trip only
when the inverter output frequency is the same as the command
frequency.
4: OT Trip

Detects over torque during operation and generates a trip.
5: UT CmdSpd Warn

Detects under torque and outputs warning only
when the inverter output frequency is the same as the command
frequency.
6: OT Warning

Detects under torque during the operation and
outputs warning.
7: UT CmdSpd Trip

Detects under torque and generates a trip only
when the inverter output frequency is the same as the command
frequency.
8: UT Trip

Detects under torque during operation and generates a
trip.
OU.68, 71
Torque detection
level
Sets the torque detection level of torque detection 1, 2. The set value
is a% of the motor's rated current. The detection level must be higher
than Ba.14 no load current value.
OU.69, 72
Torque detection
Sets the delay time on torque detection 1, 2. When over or under
torque is detected, a warning or trip is output after the torque detection
