This parameter is proportional to the length of the vector in the x axis of the reference frame and is equivalent to the reactive current (magnetising
current) in each output phase in amps.
This parameter gives an indication of the internal CURRENT_LIMIT_MAX as defined above.
This parameter gives a continuous indication of modelled motor temperature as a percentage of the trip level.
When this parameter reaches 75% (and the load is above 105%), the drive will flash 'OVL.d' on the display to indicate that the motor temperature is
excessive and the motor current should be reduced to stop the drive from tripping on 'It.AC’
When this parameter reaches 100%, the drive will give an 'It.AC’ trip or apply a restriction on the current limit (see Pr 4.16 on page 68).
The level of the accumulator is given by:
Also see Pr 4.15 on page 68.
This parameter indicates the drive loading as a percentage of rated active current, where the 100% rated active current is Pr 5.07 x Pr 5.10.
Therefore:
A positive value in this parameter indicates motoring load and a negative value indicates a regenerating load.
0: Ld Value of Pr 4.20 displayed.
1: A Value of Pr 4.01 displayed.
This parameter defines whether the load indication in the display status mode displays percentage load or output current
