Table 6-58 Stator Resistance Estimator Menu (3300) Parameters
Parameter ID Unit Default Min Max Description
Stator resistance est 3310 Off Enable or disable the stator resistance estimator
function:
• Off
• On
This parameter is not implemented.
Stator resis filter
gain 3320 0.0 0.0 1.0 Stator resistance estimator filter gain.
Stator resis integ
gain 3330 0.002 0.0 1.0 Stator resistance estimator integral gain.
Table 6-59 Braking Menu (3350) Parameters
Parameter ID Unit Default Min Max Description
Enable braking 3360 Off Enable or disable DFB.
Note: You must be aware of torque pulsations and
motor heating produced with this method.
Pulsation frequency 3370 Hz 275.0 100.0 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.
Brake power loss 3390 % 0.25 0.0 50.0 Amount of high frequency losses at the onset of
braking. Affects the limit of the V
q
component of
output braking voltage.
VD Loss Max 3400 pu 0.25 0.0 0.5 Max amplitude of the loss inducing voltage. Use
this to adjust the braking torque. Sets the maxi‐
mum loss limiting (V
d
) voltage amplitude.
Braking constant 3410 pu 1.05 0.0 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
q
and V
d
voltage amplitude of losses in the motor and in‐
creases braking.
Exercise caution to prevent a motor thermal trip.
