The control word serves to influence the control functions.
Bit 0 Flying restart completed
This bit enables the control to report the acceptance of the recorded
speed to the "flying restart" function. Thus, the flying restart process is
completed.
Bit 1 Block flying restart
TRUE: the flying restart process is blocked.
Bit 4 Set load value
TRUE: set load value.
Bit 5 Select new actual position
TRUE: define new actual position.

Switching frequency changeover
The output voltage of the inverter is a DC voltage with sine-coded pulse width modulation
(PWM). This corresponds by approximation to a AC voltage with variable frequency. The fre-
quency of the PWM pulses is adjustable and is called "switching frequency".
Details
The switching frequency has an impact on the smooth running performance and the noise
generation in the motor connected as well as on the power loss in the inverter. The lower the
switching frequency, the better the concentricity factor, the smaller the power loss and the
higher the noise generation.

Switching frequency
Selection of the inverter switching frequency.
Abbreviations used:
•
"Variable": adaptation of the switching frequency as a function of the
current. The carrier frequency is reduced dependent on the heatsink
temperature and the ixt-load.
•
"Fix.": the carrier frequency is fixed, no frequency reduction.
•
"Drive-optimised": reduces the capacitive currents from the motor to
the earth.
•
"Min. Pv": increases the capacitive currents from the motor to the
earth.
