Inverter module
The inverter module in the motor receives serial commands via RS485 from the control unit and controls the motor by
performing the required manoeuvre. In the event an obstacle is encountered, the manoeuvre is reversed automatically
and the alarm condition is transmitted to the control unit, which executes the same manoeuvre using the second motor,
if present, maintaining synchronisation of the automation system.
