Field Description
Gate drive dead time in units of system clock cycles (e.g., 30 ns
with 33 MHz clock).
Space vector modulator scale factor. This register, which
depends on the PWM carrier frequency, should be set as follows:
ModScl = PwmPeriod * sqrt(3) * 4096 / 2355
where PwmPeriod is the value in the PwmConfig write register
group’s PwmPeriod register.
This parameter provides a guard band (scaling: 1 = 30nsec) such
that PWM switching will not migrate into the current feedback
sampling instant (Sync Pulse region). This guard band is provided
to improve feedback noise. The parameter only applies to the 3-
phase Space Vector modulation scheme.
Please do not modify
this parameter without consulting a motor drive FAE.

Field Description
Rotating frame Iq component and Id component current feedback
scale factor. Constant used to scale current measurements before
they are used in the field orientation calculation. This is a 15-bit fixed-
point signed number with 10 fractional bits that ranges from –16 to +
16 + 1023 / 1024.
This parameter specifies the delay time (1 = 1 sec) to restart current
offset measurement after a stop command is issued. Only applies if
Leg Shunt current feedback is selected.12-bit signed value for V
phase current feedback offset. When the IfbOffsEnb bit in the
SystemControl write register group is "0" this value is automatically
added to each current measurement in hardware.
