Name Description
22 Overload Detection (N.O.)
If the drive detects overload based on the conditions set for Overload Detection 1 or 2, then this
digital output will switch ON.
The digital output will switch OFF when oL5 is cleared from the keypad display.
23 Weight Det N.C.
If the drive detects overload based on the conditions set for Overload Detection 1 or 2, then this
digital output will switch OFF.
The digital output will switch ON when oL5 is cleared from the keypad display.
◆ Overtorque Detection
This function limits drive operation depending on how high the drive torque reference or the output current is in
order to provide mechanical protection to the crane. If the drive detects an overtorque situation, then it displays
oL3 [Overtorque Detection 1] or oL4 [Overtorque Detection 2] on the keypad. You can set 2 levels for overtorque
detection, and 2 types of action to take after detecting overtorque.
Note:
The overtorque detection function is disabled when the Run command source is set to the keypad.

S6-06 Overtorque Detection Time 2
If the motor current and motor torque exceed the value set in S6-05 for longer than the time set in
this parameter, then Overtorque 2 will be detected.
oL4
S6-09 Torque Detection Filter Time
Sets the time constant for a primary filter to the torque reference or to the output current used to
detect overtorque.
