1.
Activate the AUTOM input.
2.
Apply a voltage to the ANA_IN input.
→
The motor rotates at the speed which is proportional to this
voltage.
NOTE
The INV_DIR input can be used for inverting the motor’s sense of
rotation.
3.
Deactivate the AUTOM input.
→
The motor is decelerated.
NOTE
The motor can be deenergized with the CURRENT_OFF signal. In this
state, it does not have any holding torque.
To quickly stop and resume a motor movement, use the STOP input.
