Inverter start/stop
Inverter operation
The parameter 189.01 Inverter operation can be used to shut down the inverter in a
controlled way and to disable autonomous operation. In addition to shut down, inverter
operation also sets the main state machine to the initial state and also affects grid
monitoring delays. Grid monitoring delays are restarted after enabling the operation.
Note: Software update is possible only if inverter operation is disabled.
Transfer trip
The Transfer trip function allows to remotely shut down the inverter as fast as possible.
The parameter 189.04 SCADA transfer trip can be written by, for example, SCADA
systems. In addition, the IO signal can be used to signal the inverter to shut down. The
input that is the source for the transfer trip signal can be selected with parameter 189.03
IO transfer trip source signal.
When transfer trip is triggered an event can be generated. The generated event depends
on the action selected by parameter 189.05 Transfer trip event.
Shut down
The inverter can be signaled to shut down in a controlled way using an IO signal. The
parameter 189.06 IO shutdown source can be used to select which input is the source for
the shutdown signal. In addition, parameter 189.07 SCADA shutdown can be used to
signal the inverter to shut down.
When shut down is requested, an event can be generated. The generated event depends
on the action selected by parameter 189.08 Shutdown event.

Control interfaces
Control panel
The inverter can be monitored and controlled locally from a single ACS-AP-I assistant
control panel.
Fieldbus
The inverter can be connected to several automation systems through fieldbus interfaces.
For information on how to control/monitor the inverter through an external control system,
see Communication interfaces on page 181.
