Selection Active Line Module for Sinamics S120

Leshiy20b Posts: 1 Rating: (0)	Hello. Please help with the selection and validation of overload "Active Line Module" for "Sinamics S120". For the situation where the engines operate in a cycle of high overload. The "Motor Modules" selected with the maximum motor current. What recommendations are to select "Active Line Module"? And the second question. What are "Capacitor Modules in booksize format"? How to check the need for their use? Need documentation in English or Russian. Thanks in advance.

Normally you don`t need a capacitor module, if you use a ALM. For special applications (for example flying shear), it make sense to store the energy in the DC- link. The rotary energy you can calculate with 1/2J(w1²-w2²) and the stored energy in the DC- link with 1/2C(Vmax²-Vmin²). Depend on the motors (for example with 1PH8) a max. DC- link voltage of 720V is possible. We calculate with a min. Voltage of 580V (depend on the line supply). If you need for example 100mF for storageing energy, we have special capacitors too.
