| | | The MAC series of brushless servo motors with integrated electronics represents a major step forward. All the necessary electronics in a servo system are integrated in the motor itself. In the past, a traditional motor system has typically been based on a central controller unit located remote from the motor. This configuration however has the negative effect that installation costs are a major part of the total expense of building machinery. The basic idea of the MAC motors is to minimize these costs but also to make a component that is much better protected against electrical noise which can be a typical problem when using long cables between the controller and motor. The servo motor, hall sensor, encoder and electronics are specially developed by JVL so that together they form a closed unit in which the power driver and controller are mounted inside the motor in a closed section. | | |
| | | The advantages of this solution are: • De-central intelligence. • Simple installation. No cables between motor and driver. • EMC safe. Switching noise remains within motor. • Compact. Does not take space in cabinet. Typically a 3/5 core cable is used from PLC or similar to MAC motor. • 115/230V AC for driver voltage. • 24VDC for control circuits. • Option for built-in brake. • Uses the same expansion modules as the MAC 50-141 series. • Built-in mains supply filter. • CE approved/UL pending. • Low price. | | Interface possibilities to the MAC motor: • From PC/PLC with drive-commands via RS232/RS485/ RS422 • Pulse/dir. or quadrature inputs. ■ 10 bit ±10V input for speed or torque control. • A+B encoder output. • Register mode via 4 inputs or serial commands • Option for uPLC built-in. • Option for Fieldbus. Profibus-DP, CanOpen, Devicenet, Highspeed serial bus etc. | | |
