The maximum for Pr
4.08
and Pr
4.20
is defined by this parameter.
0
: OFF Low speed thermal protection mode disabled
1
: On Low speed thermal protection mode enabled
See Pr
on page 68 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
)
Modification of this parameter may be required when using the drive with a high- speed motor, which inherently has low inductance.
This parameter should only be set to On if OI.AC trips are occurring when the drive is carrying out a mains loss stop or DC injection brake with a high
speed motor.
Only available with drive firmware V01.08.04 onwards (size 2 to 6).
