2.3. Supported Motor-Sensor Configurations
The IDMx40 drives support 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
4
, while the same commands, expressed in IU units, refer to the
motor.

. 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

Nominal values cover all cases. Higher values are possible in specific configurations. For details contact Technosoft
2
1-2kHz cover all cases. Higher values equal with torque loop update frequency are possible with quadrature encoders
