Configuration
Check whether the available current from the electronics cover power supply unit is sufficient for the total current demand of all consumers:
- Determine the available current from the electronics cover power supply unit according to the following table:
Electronics cover | Available current | Maximum current |
|---|---|---|
Size 1 Size 2 without fan | 820 mA | 1250 mA |
Size 2 with fan | 1180 mA | 1600 mA |
- Sum up the current demand of all consumers according to the following table:
Consumer | Current requirement | ||
|---|---|---|---|
| Electronics cover (Basic requirement) | Size 1 Size 2 without fan | 210 mA |
Size 2 with fan | 570 mA | ||
1st | MOVILINK® DDI encoder (..Z) | 120 mA | |
2nd | Keypad (CBG..) | 50 mA | |
3rd | Safety technology | STO connected | 0 mA |
Internal STO jumpered | 20 mA | ||
/SBA option | 90 mA | ||
/SLA option without EI7C-FS | 100 mA | ||
/SLA option with EI7C-FS | 250 mA | ||
4th | Safe digital inputs F-DI (Only for drive units with option /SLA or /SSA) | Max. 300 mA per F-DI Max. 300 mA in total | |
5. | Digital inputs DI (Sensor supply) | Max. 500 mA per DI Max. 500 mA in total | |
6. | Digital outputs DO | Max. 50 mA per DO Max. 100 mA in total | |
- Compare the total current demand of all consumers to the available current without external 24 V supply (i.e. 24 V through internal power supply unit):
If the total current demand of all consumers is greater than the available current from the electronics cover power supply unit, you must supply the drive unit with 24 V externally.
In this case, the specified maximum currents must not be exceeded.
