Threshold "OL2 Load thr" must be set to a value higher than "OL1 Load thr," otherwise the value of "OL2
Load thr" is automatically forced to 0.
The actions to be taken if thresholds are exceeded are specified in the "OL1/OL2 time" and "OL1/OL2 Action"
parameters on the ALARM CONFIG menu.
The actions must be increasing (example: OL1 Action = Warning / OL2 Action = Alarm).
Note: If you use –ELS (electric shaft) configuration):
 The thresholds are set in % only on the drive defined as "virtual master" ...–ELS-VM. The "virtual master"
receives the load %s of each shaft from the slaves.
 The action if the threshold is exceeded must be specified only on drive...–ELS-VM.
 Function activation state will be shown on the monitor on drive ...-ELS-VM
Possible configurations for "OL1 Action" and "OL2 Action":

In the graph shown on previous page, parameter ALARM CONFIG\ OL1 Action is set as "Warning" and
therefore does not interfere with any command to the drive. The warning state resets automatically when the
value returns within the allowed torque (current) limits.
Parameter ALARM CONFIG\ OL2 ACTION is set as "Alarm" and therefore forces the drive into alarm and
closes the mechanical brake. The alarm must be reset manually.

OL1 Load thr
Threshold 1, to identify an excessive load.
In V/f mode, the OL1 Load thr parameter is a % of nominal current of the motor.
In FOC CL or FOC OL mode, the OL1 Load thr parameter is a % of nominal torque of the
motor.oglia 1, per identificare una carico eccessivo.
OL2 Load thr
Threshold 2, to identify an excessive load.
In V/f mode, the OL2 Load thr parameter is a % of nominal current of the motor.
In FOC CL or FOC OL mode, the OL2 Load thr parameter is a % of nominal torque of the
motor.
Delay to start OL
The delay time starts after the inverter is enabled and the brake is opened..
