Explanation
Standstill detection, speed threshold (Factory setting: 20 rpm)
The moment of inertia estimator only measures the load torque for speeds ≥ p1226.
p1226 also defines from which speed the inverter switches-off the motor for OFF1
and OFF3.
Moment of inertia estimator accelerating torque threshold value (factory setting:
10 %)
Moment of inertia estimator change time inertia
(factory setting: 500 ms)
Moment of inertia estimator change time load (facto-
ry setting: 10 ms)
Moment of inertia estimator load torque positive direction of rotation(factory setting:
0 Nm)
Moment of inertia estimator load torque negative direction of rotation(factory setting:
0 Nm)
Moment of inertia precontrol configuration (factory setting: 0000 bin)
.00 1 signal: activates calculation of the characteristic (p5312 ... p5315)
.01 1 signal: activates moment of inertia precontrol
p5310.00 = 0, p5310.01 = 0
p5310.00 = 1, p5310.01 = 0
p5310.00 = 0, p5310.01 = 1
p5310.00 = 1, p5310.01 = 1
Moment of inertia precontrol status word
.00 1 signal: New measuring points for the characteristic of the moment of inertia
precontrol are available
.01 1 signal: new parameters are been calculated
.02 1 signal: moment of inertia precontrol active
.03 1 signal: the characteristic in the positive direction of rotation has been calcu-
lated and is ready
.04 1 signal: the characteristic in the negative direction of rotation has been calcu-
lated and is ready
.05 1 signal: The inverter writes actual results to the parameter
The lower that p1561 or p1562
is, the shorter the moment of
inertia estimator measure-
ments.
The larger p1561 or p1562 is,
the more accurate the results
provided by the moment of
inertia estimator.
Deactivating moment of inertia precontrol
Adapting the moment of inertia precontrol
Activating the moment of inertia precontrol.
The characteristic of the moment of inertia
precontrol remains unchanged.
Activating the moment of inertia precontrol. The
inverter adapts the characteristic in parallel.
