3.What is the difference between MDS-DH-V2-2010 and MDS-DH2-V2-2010?
| Item | MDS-DH-V2-2010 | MDS-DH2-V2-2010 | Description |
|---|---|---|---|
| Series Position | Early MDS-DH series | Upgraded MDS-DH2 series | DH2 is a newer high-performance model |
| Power Supply | DC 513–648V only | AC 380–480V / DC 513–648V | DH2 can be directly connected to three-phase mains |
| Rated Current | 3.9A for both axes | Axis A: 3.9A, Axis B: 2.3A | DH2 uses asymmetric power for main/auxiliary axes |
| Control Performance | Standard current loop | Faster current loop, high-gain control | DH2 has better response and positioning accuracy |
| Hardware Design | Conventional heat dissipation | High-efficiency heat sink & low-loss module | DH2 is more compact |
| Safety Function | No built-in STO | Built-in STO available | DH2 has higher safety level |
| CNC Compatibility | Older CNC systems | Latest Mitsubishi CNC systems | DH2 is more suitable for upgrades |
