3. Closed-loop control of
load position using an encoder on load
, combined with open-loop
control of
a 2 phase step motor
in speed, with speed reference provided by the position
controller. The motion commands in both SI and IU units refer to the load.
Figure 2.3.
Encoder on load. Closed-loop control: load position, open-loop control: motor speed
4. Closed-loop control of
a 2-phase step motor
in position, speed or torque. Scaling factors
take into account the transmission ratio between motor and load (rotary or linear). Therefore,
the motion commands expressed in SI units (or derivatives) refer to the load
1
, while the same
commands, expressed in IU units refer to the motor.
