1.3.5 Engineering the SIMODRIVE 611 line supply infeed for
SIMODRIVE POSMO SI/CD
When calculating the charge limit of the SIMODRIVE line supply infeed mod-
ules, for charging the ”DC link” an equivalent capacitance for POSMO SI/CD
should be used for each unit depending on the pre--charging circuit of the line
supply infeed module.
The number of POSMO units connected to a line supply infeed module is lim-
ited as a result of the charge limits.
