3.7
47.53
Id predicted
This parameter displays the predictive current Id determined by the current prediction pro-
cedure, if the current prediction procedure is switched on.
47.54
Back EMF estimated
EMF acting in the q-direction. Required for field angle monitoring of PMSM.
47.55
SM Phi error
Display of the identified field angle deviation of the PMSM.
47.65
Current controller cycle time
Display parameter for the cycle time of the current controller. The cycle time results from
the setting of
Z
130.15
–
PWM Frequency.
The current controller cycle time must not exceed the
Z
1.8
–
RT0-Cycle time. This is mon-
itored and as the case may be the error 501 will be triggered which inhibits enabling of
the drive.
47.70
Alpha voltage of dead time compensation
Alpha component of the dead time compensation
Because of the current actual values, the PWM frequency (according to setting
Z
123.1
–
bit 3) and of the UDC-link actual value evaluated dead time voltage (this means the nom-
inal dead time voltage), affected by the dead time compensation factor (
Z
47.50
–
).
47.71
Beta voltage of dead time compensation
Beta component of the dead time compensation
Because of the current actual values, the PWM frequency (according to setting
Z
123.1
–
bit 3) and of the UDC-link actual value evaluated dead time voltage (this means the nom-
inal dead time voltage), affected by the dead time compensation factor (
Z
47.50
–
).
