Design
Th eplug arrangement can be selected and varied as desired.
A possible arrangement could be as follows:
- Power supply (M23)
- Auxiliary voltage 24 VDC / brake (M12)
- RS 232 connection (M12)
- Fieldbus BUS IN (M12)
- Fieldbus BUS OUT (M12)
- Input connection (M12)
4 digital inputs and 1 analogue input
supply from the drive 24 VDC - Ouput connection (M12)
4 digital outputs
All control components required for motor operation are integrated in the drive housing. This includes:
- digital, sinusoidal commutated servo amplifier, consisting of the following components:
power supply unit (voltage supply 230 VAC),
power end stage,
positioning and sequence control,
internal ballast resistor, - digital position and speed controller
By means of heat insulation, the electronics is protected against increased motor temperatures.
Due to various programming possibilities of the integral microcontroller, the Milan drive advanced can be quickly and easily be adapted to the specific application.
Program procedures can be defined. The overriding controls are relieved and the data exchange is reduced.
The Milan drive advanced therefore follows the clear trend towards decentralization of functions within the automation technology.
With the maintenance-free resolver, the rotor position of the motor is registered, allowing the speed and position to be derived.
The resolution is 4096 increments per revolution, as a pre-condition for a high precision of positioning.
As an alternative, the drive may also be equipped with a multi-turn absolute encoder.
A GFC spur or bevel gear unit can be mounted to the DIN standardised flange/ shaft unit, for example..
The Milan drive advanced is also implemented in combination with planetary gearings of the most diverse manufacturers.
The synchronous servo motor has a low rotor moment of inertia – basis for the excellent motor dynamics. By using high-quality materials, a long lifetime is achieved. Therefore, no maintenance is required. |  |
Holding brake (option)
If a holding brake is used, then the current position is held reliably. It prevents any change in position after the motor has been switched off, e.g. due to the effects of gravity or outside forces.
The brake can be activated via internal programming.
Static holding torques
| MDA 35.1 | 2,0 Nm |
| MDA 56.1 | 4,5 Nm |
| MDA 63.1 | 9,0 Nm |
A Profibus DP or CAN-Open interface is installed within the drive by using an additional plug-in module.
The integrated bus termination resistors can be activated or deactivated by means of the software.
Other fieldbus interfaces on request.
