PLL gains and scaling parameter values
Changing PLL gains from the default values or setting scaling parameter values incorrectly can
cause unintended results that affect performance and disable drive protections.
Scaling parameter values must match actual hardware ratings.
Never change scaling parameter values from actual hardware ratings.

Min Max Description
0.0 150.0 Compensate the flux vector angle for sampling
delay on high speed motor operation.
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 = Power cell carrier frequency

High switching frequencies may result in some
derating due to increased switching losses. Con‐
sult Siemens customer service for derating values.
Min Max Description
0.0 200.0 Proportional gain of input phase-locked loop
(PLL).
0.0 12000.0 Integral gain of input PLL.
0.0 2.0 Set the scaling for input current feedback. Default
value is normally adequate.
50 3000 Secondary side turns for input current CT, with
primary turns equal to 5.
0.0 2.0 Set the scaling for input line voltage feedback.
Default value is normally adequate.
1 3000 Secondary turns input voltage PT.
Access the cell input control parameters.
1 32767 Set scaling for input nominal value. This is the
sum of the two input resistors per phase.
< 167 Hz, f = 600 Hz is typically adequate.
