2.4Cables for the DC bus
Minimum requirement A cable for the common DC bus must meet the following require- ments.
Shield: | Shielded at cable lengths of > 0.2 m |
|
|
Twisted Pair: | Twisted pair at cable lengths of > |
| 0.2 m |
Cable: | Two wires, shielded |
|
|
Maximum cable length between 2 | 3 m |
drives: |
|
Special characteristics: | • Insulation must be rated for the |
| DC bus voltage |
| • Conductor cross section accord- |
| ing to the calculated current, but |
| at least 2* 6 mm2 (2* AWG 10) |
The connection of the fuses for the DC bus must be rated for the total maximum continuous current on the DC bus of all drives connected via the DC bus. Analyze the most critical case in your application (for example EMERGENCY STOP) and select an appropriate conductor cross section.
