In state 0 of the input or the assigned bit, the first current limiting is active.
In state 1 of the input or the assigned bit, the second current limiting is active.
CL2 [2nd current limit]
1)
0 to 1.65 In
2)
1.5 In
2)
Second current limiting This parameter can be activated if [2nd current limit] (LC2) is not equal to [No] (nO) .
The adjustment range is limited to 1.36 In if [Switch frequency] (SFr) is under 2 kHz.
Note:
If the setting is less than 0.25 In, the inverter can remain in error mode [output phase loss] (OPF) , if this has been enabled, see
"THERM. MOTOR PROTECTION (tHt) and LOSS OF MOTOR PHASE (OPL)" on page 292 . If it is below the no-load current of the
motor, the limitation has no effect.
Caution!
Make sure that the motor is designed to this current, since these are susceptible to a demagnetization.
Failure to follow this instruction can result in equipment damage.

1) This parameter can also be accessed via the [SETTINGS] (SEt-) menu.
2) In is the same as the rated current specified in the installation instructions and on the nameplate of the inverter.
Parameter that can be modified during operation or when stopped.
