Low torque detection signals

: Undertorque detection selection
: Undertorque detection level during power running
: Undertorque detection level during regenerative braking
: Undertorque detection time
: Undertorque detection hysteresis
• Function
If the torque remains below the level specified with
specified with
= : Alarm signal output (No tripping)
With an output terminal function selection parameter, the inverter can be set so as to issue an
undertorque alarm.
The output terminal function number is 142 or 143 (reverse video).
= : Trip signal output
If the torque is found to be below the value set with
