Example

The drive unit has the following consumer:

• Basic requirement of electronics cover size 1 (-210 mA).
• MOVILINK^® DDI encoder (-120 mA)
• Keypad (-50 mA),
• The STO is internally jumpered in the inverter (-20 mA).

Without an external 24 V supply, 420 mA are still available for the DC 24 V output after deducting the basic requirement and the electricity requirement of the consumer.

820 mA - 210 mA - 120 mA - 50 mA - 20 mA = 420 mA

However, the electricity requirement of the DC 24 V output is no greater than 100 mA.

Therefore, an external 24 V supply is not required.
