Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
For high-performance industrial motion control, the Delta Electronics ASD-A1521-AB serves as a reliable 1.5 kW AC servo drive within the versatile ASDA-A product family. This drive is engineered to manage precise velocity, torque, and position configurations in automated systems. Using Space Vector Pulse Width Modulation (SVPWM) control for the main circuit, it ensures optimal energy efficiency and smooth motor operations.
The ASD-A1521-AB accommodates complex command structures through external pulse trains or internal parameter settings. It features an integrated dynamic brake to provide secure, rapid deceleration in demanding cyclic operations. With natural air circulation cooling, this unit reduces external mechanical failures while maintaining a compact physical footprint, making it ideal for integration into standard control cabinets.
| Manufacturer | Delta Electronics |
| Model/Part Number | ASD-A1521-AB |
| Product Type | AC Servo Drive |
| Output Power | 1500 W (1.5 kW) |
| Main Circuit Control | SVPWM (Space Vector Pulse Width Modulation) Control |
| Feedback Resolution | 2500 ppr (10000 ppr internal) |
| Cooling System | Natural Air Circulation |
| Max. Input Pulse Frequency | 500 Kpps (Line driver) / 200 Kpps (Open collector) |
| Speed Control Range | 1:5000 |
| Analog Input Voltage Range | 0 to plus/minus 10 VDC |
| Analog Input Resistance | 10k Ohm |
| Dynamic Brake | Built-in |
| Weight | 1.5 kg |
Ensure the drive is mounted vertically on a flat, unpainted metal surface to maximize heat dissipation. Because the ASD-A1521-AB relies on natural air circulation, maintain a minimum clearance of 50 mm above and below the unit, and 10 mm on either side. Ground the drive properly using a low-impedance copper wire connected to the main system ground. Keep control and feedback cables shielded and routed separately from high-voltage power lines to prevent electromagnetic interference.
