6.38 Motor total voltage smoothed
Calculated total voltage smoothed at motor.
For the calculation the dead time voltages are compensated with 100%, independent of
the value of the dead time compensation factor
Z47.50–, i.e. it doesn't matter if the dead
time compensation in the motor is active or not.
The parameter is smoothed with the time constant 1,25 ms.
The unit of the parameter is [V], phase-to-phase voltage effective.
6.39 Motor I
2
t warning threshold
Settable warning threshold for the motor I
2
t monitoring (see Z6.28– Motor I
2
t actual val-
ue).
If the motor I
2
t actual value Z6.28– exceeds the warning threshold, the warning 219
"Warning threshold motor I
2
t exceeded" is generated. With a fixed hysteresis of 10% be-
low the warning threshold the warning is withdrawn again.
If the value for the warning threshold is 0, there is no warning.

2
t)– from page 717.

6.42 Smoothing time electr. motor power display
Smoothing time constant for the motor real power display Z6.32–.
6.43 Motor I
2
t monitoring mode
The accordant implementation to calculate the l
2
t value of the motor must be selected.
Generally, the parameter is assigned to zero (speed-dependent monitoring is deactivated
and the monitoring of the total current is activated). See
ZOverload monitoring of the mo-
tor (I
2
t)– from page 717.
NOTE!
If the power indication >6.32< is evaluated and PWM frequency changes are made
during operation, the adaption of the dead time compensation must be activated after
the PWM frequency (see
Z123.1– bit 3) independent of the dead time compensation
being active in the motor control or not (see Z47.50–).
