STATUS
In operating systems 2.0 or earlier, the SFB value reflected the type of motor
that the drive auto-detected. In operating system 2.10 and beyond, you also
can set a feedback type with the SFB command.
SFB1 sets auto-detect mode and is the default setting. In auto-detect mode
the SFB command reports the detected drive-type upon power-up. If SFB is
set to a value other than 1, the drive assumes that type of encoder is
attached and does not try to auto-detect the feedback type.
In operating system 3.10 and beyond, the Aries Resolver option will report an
SFB value of 3. Changing the value will not affect the drive operation and it
will return to 3 on power-up.

This command is only valid in DMODE4 (velocity mode) and DMODE6 or 7
(position mode). Use the Integral Gain (SGI) command to set the gain of the
integral term in the control algorithm. The primary function of the integral gain
is to reduce or eliminate final position error (e.g., due to friction, gravity, etc.)
and improve system accuracy during motion. If a position error exists
(commanded position not equal to actual position—see TPER command), this
control signal will ramp up until it is high enough to overcome the friction and
drive the motor toward its commanded position. If acceptable position
