3570 % 0.0 0.0 150.0 Compensate the 󹪞ux vector angle for sampling
delay on high speed motor operation.
Carrier frequency 3580 Hz 600.0 100.0 1550.0 Enter the IGBT switching frequency. The control
adjusts the entered value according to available
resolution from the modulator registers, e.g., if
you enter 400.0, the actual frequency may be
398.6:
f
C
= Power cell carrier frequency
f
O
= Drive rated output frequency
For f
O
< 167 Hz, f
C
= 600 Hz is typically adequate.
A smaller value of f
C
can be chosen provided
300 Hz < f
C
> (3.6 x f
O
) Hz.
For f
O
= 167 to 330 Hz, 1550 Hz > f
C
> (3.6 x f
O
) Hz.
High switching frequencies may result in some
derating due to increased switching losses. Con‐
sult Siemens customer service for derating values.

Sum
3045 kOhm 3000 1 32767 Set scaling for input nominal value. This is the
sum of the two input resistors per phase.
CAUTION
PLL gains and scaling parameter values
Changing PLL gains from the default values or setting scaling parameter values incorrectly can
cause unintended results that a󹪜ect performance and disable drive protections.
Scaling parameter values must match actual hardware ratings.
Never change scaling parameter values from actual hardware ratings.
