.......Specifications differ according to the date assembled. 

Refer to page 316  

to check the SERIAL number.

If the output torque (current equivalent to the torque) exceeds
the current level for the torque limit operation, the output torque
is limited by adjusting the output frequency. The torque limit
operation level in such a case is based on the rating torque of
the motor.

Torque limit operation stops acceleration (makes deceleration)
during acceleration, makes deceleration during constant speed,
and stops deceleration during deceleration.

When torque limit operation is performed, the OL signal is
output.

NOTE

If an overload status lasts long, a drive unit trip (e.g. electronic thermal relay function (E.THM)) may occur.

If the speed drops to 18r/min or lower due to the torque limit operation and stays there for 3s, the fault indication
(E.OLT) appears, and the drive unit outputs are shut off.
