Description of parameters
2.4.2.9 Synchronisation ID1602
This input is used to the synchronisation of the external network when the drive is
already generating network but in a different phase. It can be used only when OPT-D7
board is installed and measurements are on the external network side.
When the input is activated, the drive uses line frequency as a frequency reference and
adjusts the voltage angle to correspond with the line voltage angle with given hysteresis.
2.4.2.10 Connect to Net ID1604
A command to close NET (shore) contactor. The closing will take place only when the
drive is synchronised to the grid (shore).
This function is needed when the drive is already making a grid and needs to be
synchronised to another grid that cannot be synchronised to the grid that the drive is
making.
DC
2.4.2.11 Forced AFE Mode
Forces the drive control mode to 0 = AFE mode.
2.4.2.12 NET Contactor
This parameter determines if the drive monitors the status of the NET contactor (shore)
of the unit. The drive will switch from Island mode to Micro Grid mode if the control
mode 4 / Island – Micro Grid is used.
If the status of the NET contactor is not monitored in the system, the option
must be selected.
2.4.2.13 Cooling Monitor ID750
OK input from the cooling unit.
If the status is not monitored in the system, the option
