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
The maximum for Pr 4.08 and Pr 4.20 is defined by this parameter.
0: Low speed thermal protection mode disabled
1: Low speed thermal protection mode enabled
See Pr 4.16 on page 51 for details.
Pr 4.26 shows the torque producing current (Pr 4.02) as a percentage of the active torque producing current, but with an additional adjustment above
base speed so that this parameter shows percentage torque. Below base speed, Pr 4.26 is equal to Pr 4.20. Above base speed the percentage
torque producing current (Pr 4.20) is adjusted as follows:
Pr 4.26 = Pr 4.20 x motor rated frequency (Pr 5.06) /post ramp reference (Pr 2.01)
