Dc intermediate circuit can absorb a small amount of energy but using the circuit requires careful calculation for a calculation example see appendix a motor s kinetic energy vs dc capacitors electrical energy 15

Dimensioning procedure 15
If you plan to connect one or more acsm1 drives to the same dc bus with acs355 drives take into account the following recommendations 15
Instead of an external dc chopper you can use acsm1 s brake chopper which is independent of common dc operation acs355 has a brake chopper as well but in this case it cannot be used 15
Prefer acsm1 as the supply unit because its supply diode bridge is over dimensioned 15
Use external ac chokes in supply even though not recommended for acsm1 drives 15

Acs355 dc fuse ratings 32
If there is no overload the fuses can be dimensioned directly according to the power of the drive 32
Technical data of common dc applications 32
The fuse rating depends on the fuse type gg or ur and the temporary overload of the drive 32
The recommended ratings rule of thumb are presented in the table below the voltage rating of the fuses is 690 v 32
With gg fuses a rating one size smaller can be taken 32
With ur fuses the rating is determined by the maximum instantaneous dc current because fuses work fast in practice the fuses have to be selected for a current about two times higher than the dc current calculated from the nominal power 32
