Note
Principle of the precharging circuit
SINAMICS PM330 Power Modules include a half
-controlled thyristor bridge as rectifier
circuit. As a result of the precharging principle with phase control, precharging is only started
when all of the enable signals are available and by setting the ON/OFF command
(p0840
= 1).
The DC link is then fully charged af
ter approximately 4 s.
The Power Modules can be used with the following Control Units, including all
communication versions with firmware version from 4.6 HF7 and higher.
CU230P-2 PN
-0BB30-1FAx
CU230P-2 DP
-0BB30-1PAx
CU230P-2 HVAC
3243-0BB30-1HAx
Operation with Control Units other than those listed above is not permitted.
