IBL2403 Technical Reference
2.3. Supported Motor-Sensor Configurations
IBL2403 supports the following configurations:
1. Position, speed or torque control of a
brushless AC
rotary motor
with an
incremental
quadrature encoder
on its shaft. The brushless motor is vector controlled like a
permanent magnet synchronous motor. It works with
sinusoidal
voltages and currents.
Scaling factors take into account the transmission ratio between motor and load (rotary or
linear). Therefore, the motion commands (for position, speed and acceleration)
expressed in SI units (or derivatives) refer to the load
1
, while the same commands,
expressed in IU units, refer to the motor.

2. Position, speed or torque control of a
brushless DC
rotary
motor
with
digital Hall
sensors
and an
incremental quadrature encoder
on its shaft. The brushless motor is
controlled using Hall sensors for commutation. It works with rectangular currents and
trapezoidal
BEMF voltages. Scaling factors take into account the transmission ratio
between motor and load (rotary or linear). Therefore, the motion commands (for position,
speed and acceleration) expressed in SI units (or derivatives) refer to the load, while the
same commands, expressed in IU units, refer to the motor.

Motion commands can be referred to the motor by setting in EasySetUp a rotary to rotary transmission with ratio 1:1
