Parameter Description
Sense W Sensed voltage level at output W
BEMF U BEMF voltage on floating phase U (sesorless-only)
BEMF V BEMF voltage on floating phase V (sesorless-only)
BEMF W BEMF voltage on floating phase W (sesorless-only)
BEMF Integrator BEMF Integrator (sesorless-only)
Important Notice
All angles values entered or displayed by the controller are in 0-511 value where 0 =
0 degrees or radians, and 511 is 360o or 2r radians.
Sensor Linearity Correction
For Sin/Cos, Resolver and SSI encoders, it is possible to automatically check and even-
tually apply automatic correction to the sensor linearity. From the diagnostics tab, select
channel 1 or 2 and press the “Sensor Linearity Correction” button. The motor will spin for
a few electrical revolutions and then stop.
