 Configurable Motion Control Platform

INfOrMaTIONS

The AxM II / AxP platform has been designed with two completely separate power supplies. 
The power circuit is fed by the mains voltage, without preload timing; while the control 
circuit needs to be fed by a separate unregulated 24 V supply. This is converted, by the 
internal switching regulator, in order to supply all internal services and motor encoders at 
the appropriate voltages.
This design solution overcomes all uncertainties of timing and synchronisation between 
drive and main control cabinet, by unifying the same power supply for all services, such as 
sensors, PLCs, switches and latches. In this way, all data are memorised and reset at the 
same time, and a simple back-up is possible for all machine information without backing up 
the main power too.
The power stage without preload (and without storage capacitors in AxM range) ensures that 
the main power is available to the drive without delay whenever the mains power switch is 
operated.

Many applications involving brushless servo drives move high inertia loads in short, fast 
cycles (typical example are Cartesian robots or pick and place machines). When the load is 
moving at top speed, a significant amount of energy is stored in the load, so that a sudden 
deenergization of the brake could be dangerous. It is therefore essential that, in the event of 
an emergency, the load is braked as quickly as possible.
To solve this problem, the use of a servo motor with a safety brake is sometimes considered. 
The simple use of a safety brake, however, is wrong and dangerous for the following reasons:

 

»

Safety brakes designed for servo motors are stationary brakes. They are designed ex-
clusively to hold a motor still when deenergized, typically for vertical translations. They 
are not designed to absorb any significant energy, also because their torque to size ratio 
is extreme. If used to stop a motor, instead of keeping it at standstill, they would wear 
quickly and eventually seize.

 

»

The braking torque of an electrically driven brushless motor is always higher than that of 
the brake and the corresponding braking time is shorter.

Consequently, the function “emergency stop” must be realized as follows:
the emergency condition, because of safety regulation, must turn off the mains power to 
the drive; however, the auxiliary 24 V must be mantained, so that the drive is alive and can 
brake;
at the same time, the emergency condition must generate a 0 speed reference that brakes 
the motor at maximum torque, using the kinetic energy of the motor.
The drives regenerates energy from the motor to the DC bus until the motor speed is so low 
that the motor back EMF is less than approximately 10 V. At this speed, the DC Bus voltage 
falls, the drives locks in undervoltage and the motor is abandoned.
If the translation is vertical, and the motor is equipped with safety brake, only in this mo-
ment, the safety brake can be released. To time the release, the relay contacts in the drive 
can be used. The relay is switched by the DC Bus undervoltage, that corresponds to motor 
almost at standstill. When the emergency stop logic is realised as described, the machine 
encoders are kept alive and no index search or initialisation is required when normal opera-
tion is resumed.
