What are the motor specifications?
Looks like you are at the vfd's max kilowatt rating

From the manual:
OL3 (Overtorque detection)
Motor current exceeded the preset value in constant n098.
Overtorque detection level was exceeded because of increased leak current due to excessively long wiring.
Reduce the load, and increase the acceleration/deceleration time.
Refer to the paragraph of Carrier Frequency Selection (n080)14kHz max on page 93.
Check the wiring (increase of current caused by rare shortcircuit, etc.).
Whats the data on the motors nameplate?
Your acceleration time is 1,5 sec. Try increase is to ie. 5 sec. and see. (menu n19)
For a testrun you can disable the overtorque detection, set n096 to 0 (The feature is disabled when factory settings are loaded)
