For example, some units have the DC link charging, some do not have it. The defaultparameter settings and IO connections are valid for the version without the charging circuit.1) Use of the signal in the control program. When parameter 120.30 External charge enable has value Yes, thecontrol program reserves this I/O terminal for external charging circuit control and monitoring, and parameters110.24 RO1 source and 110.30 RO3 source are write-protected.
