Galil's digital sine wave amplifiers are ideal for applications that require precise control with a high bandwidth. The simple commissioning and integration in the motion controller make the system setup considerably easier. The latest revision of the servo amplifier is designed to further improve the excellent current resolution and accuracy.
According to Galil, this is the only digital servo controller on the market that offers a resolution of 16 bits in the current control loop. The 16 bits are available at 33 KHz switching frequency and is not only available for a lower frequency. This allows more accurate and linear current transmission over the entire available current range. As a final consequence, the precision of the regulation benefits the entire application.
| Amplifier | Number of axes | Power | Continuous current | Peak current | Voltage |
|---|---|---|---|---|---|
| D3520 | 2 | 600 W | 8 A | 15 A | 20-80 VDC |
| D3540 | 4 | 600 W | 8 A | 15 A | 20-80 VDC |
| D3740 | 4 | 1,200 W | 16 A | 30 A | 20-80 VDC |
You only need to upgrade to the new firmware revision 1.3 for this performance increase. As the aforementioned amplifiers are an optional component of a DMC-40x0 or DMC-41x3, you can have this carried out as part of a DMC update.
