Max Description
Enable or disable the stator resistance estimator
function:
• Off
• On
This parameter is not implemented.
1.0 Stator resistance estimator filter gain.
1.0 Stator resistance estimator integral gain.
Max Description
Enable or disable DFB.
Note: You must be aware of torque pulsations and
motor heating produced with this method.
5000.0 Torque pulsation frequency when DFB is enabled.
Adjust for a different torque pulsation frequency.
The control always recalculates the desired value
due to limited resolution. Adjust to avoid mechan‐
ical resonance frequencies.
50.0 Amount of high frequency losses at the onset of
braking. Affects the limit of the V
output braking voltage.
0.5 Max amplitude of the loss inducing voltage. Use
this to adjust the braking torque. Sets the maxi‐
mum loss limiting (V
10.0 Ratio of motor-induced losses to power absorbed
from load.
Always set this parameter to a value greater
than 1.0.
Setting this parameter higher increases V
voltage amplitude of losses in the motor and in‐
creases braking.
Exercise caution to prevent a motor thermal trip.
