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

, 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.

t warning threshold
Settable warning threshold for the motor I

ue).
If the motor I

t actual value

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low the warning threshold the warning is withdrawn again.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.

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

during operation, the adaption of the dead time compensation must be activated after
