Description
Rated motor torque [Nm]
Motor moment of inertia [kgm
Ratio between the total and motor
moment of inertia
Speed control configuration
CO/BO: Status word speed control‐
ler
CO: Moment of inertia total, scaled
[kgm
]
2
Acceleration precontrol scaling [%]
Setting
Displays the rated motor torque.
]
Sets the motor moment of inertia (without load).
2
Note: The converter sets the parameter when se‐
lecting a listed motor. The parameter is then write-
protected.
Factory setting: 0
Sets the ratio of moment of inertia load + motor to
moment of inertia of motor without load.
Factory setting: 1
Sets the configuration for the closed-loop speed
control.
.18 1 signal: Moment of inertia estimator active
.20 1 signal: Acceleration model on
.22 1 signal: Moment of inertia estimator retain
value when motor switched off
.24 1 signal: Shortened moment of inertia estima‐
tion is active.
p1400.24 = 1 reduces the duration of the moment
of inertia estimation.
Disadvantage: If the accelerating torque is not con‐
stant while calculating the moment of inertia, the
calculation of the moment of inertia using
p1400.24 = 1 is less precise.
Display and BICO output for the status word of the
speed controller.
.24 1 signal: Moment of inertia estimator is active
.25 1 signal: Load estimator is active
.26 1 signal: Moment of inertia estimator is engag‐
ed
.27 1 signal: Shortened moment of inertia estima‐
tion is active.
Display and connector output for the parameter‐
ized total moment of inertia.
r1493 = (p0341 × p0342) × p1496
Sets the scaling for the acceleration precontrol of
the speed/velocity controller.
According to rotating measurement of the motor
data identification is p1496 = 100%.
Factory setting: 0
