Hi all friends, i have 3 motor module that are connected to a line module, i want reforming DC bus capacitors, so i have some question about "Capacitor forming" in S120 Motor module and Line Module: i read Siemens manual but it's not so clear for me: 1- according to the attached we must connect the nominal voltage series with 100 ohm resistor to " MOTOR Terminal"! it is not dangerous for motor module? 2- we have to connect nominal voltage or we must increase voltage slowly with a period time??? 3- if we must connect nominal voltage to motor terminal, how much we must wait to sure forming done completely? 4- at first step we must do forming for motor module or Line module? or we can do both at the same time? if yes please explain for me to know how is the input supply and CU situation very thanks AttachmentLiquid-cooled chassis power units - Forming the DC link capacitors.pdf (614 Downloads) |
