To allow control without external 24V supply, by simple contact closure.Why the drive (inverter) is generating 24Vdc at its terminal strip ?
Defect or any other possible cause that should be discussed in the manual. Or missing jumper between SC and SP terminal.if its not generating then what might be the problem inside the drive ?
Then I wonder what you are asking for. It's clear from the posted schematics that the jumper must be connected to use the internal 24 V source.there wasn't any jumper between SC & SC terminal because there are 6 same brands & same model drives of different capacities are there . And none of them have any jumper between Sc & Sp .
