Torque Limited Signal
The inverter outputs the torque limited signal when it is in torque limit operation.
To enable this function, assign “

(TRQ)” to an intelligent output terminal.
Refer to section 3 for detailed explanation.

Notes:

The example circuit for terminal [11] drives a relay
coil. Note the use of a diode to prevent the
negative-going turn-off spike generated by the coil
from damaging the inverter’s output transistor.
