Initiate the save operation by setting parameter XX.00 at 1000.
Execute the operation by performing either of the following:
•
While the display is in Edit mode, press at the same time:
• Set parameter 10.38 at 100 (via serial communications)

Version _AN (if required)
Ensure the drive is disabled by checking that the Hardware enable contact is open or that parameter 6.15 is set at 0, then perform either
of the following:
•
Initiate the store operation by setting parameter 0.50 at 2 (Prog). Execute the operation by setting parameter 10.38 at 100.
• Set 11.67 Flash update enable at 1.
This is a secondary motor overload protection. The user can set Current scaling during I
2
t limit (4.53) to standard current scaling (4.07) and
the motion controller reduces torque demand in order to protect the motor. This secondary protection trips the drive on motor overload
(I2t.AC) if Motor overload warning bit (10.17) is continuously set more than Motor overload time limit.
The value set in this parameter is the trip threshold level for the SLM thermistor. Once this level has been exceeded, the drive will trip ‘Oht3’.
This bit parameter is set if the motor overload accumulator [10.58] rises above the motor overload alarm level set in parameter 4.56,
otherwise cleared.
These parameters are to compensate for the current loop and power stage offsets, which end up as speed ripple on the demanded speed.
These parameters are relayed to the SLM on power-up and are only required for high performance applications.
Please contact Technical Support for further assistance in using these parameters.
