1.) Over torque is defined as when the output torque exceeds the setting of parameter A125 (Over torque threshold %)
for a time exceeding the setting of parameter A126 (Over torque activation delay Sec.).
Over Torque:
A124 = 0000: When there is over torque, the inverter will continue to run and flashes
“OL3” until the output
torque decreases to less than the A125 set value.
= 0001: When there is over torque, the inverter coasts to stop and flashes
“OL3”. After the fault clears,
the “Reset” key on the keypad or external reset must be activated to restart the drive.
Note: When parameters A105 and / or A106 (Multifunction output terminal) = 05, the relay
Output(s) will be activated on over torque.
2.) Under torque is defined as when the output torque is less than the setting of parameter A127 (Under torque
threshold level %) for a time exceeding the setting of parameter A128 (Under torque activation delay Sec.).
