The control word serves to inuence the control funcons.
Bit 0 Flying restart completed This bit enables the control to report the acceptance of the recorded
speed t
o the "ying restart" funcon. Thus, the ying restart process is
completed.
Bit 1 Block ying restart TRUE: the ying restart process is blocked.
Bit 4 Set load value TRUE: set load value.
Bit 5 Select new actual posion TRUE: dene new actual posion.

17.13 Switching frequency changeover
The output voltage of the inverter is a DC voltage with sine-coded pulse width modulaon
(PWM). This corresponds by approximaon to a AC voltage with variable frequency. The fre-
quency of the PWM pulses is adjus
table and is called "switching frequency".
Details
The switching frequency has an impact on the smooth running performance and the noise
generaon in the motor connected as well as on the power loss in the inverter. The lower the
switching frequency, the beer the concentricity factor, the smaller the power loss and the
higher the noise generaon.

0x2939 Switching frequency Selecon of the inverter switching frequency.
Abbreviaons used:
•
"V
ariable": adaptaon of the switching frequency as a funcon of the
current. The carrier frequency is reduced dependent on the heatsink
temperature and the ixt-load.
•
"Fix.": the carrier frequency is xed, no frequency reducon.
•
"Drive-opmised": reduces the capacive currents from the motor to
the earth.
•
"Min. Pv": increases the capacive currents from the motor to the
earth.
