5.3 Output Network Variables - nvo’s
5.3.1 Node Object Status (SNVT_obj_status nvoObjStatus)
This nvo reports node object status. It will be updated every time status change. See chap. 5.1.1 for different
requests.
Identifier
Status
Invalid_request
The node has been asked for an unsupported request.
Report_mask
Report supported fields.
Comm_failure
No contact with SJ300/L300P.
In_alarm
The SJ300/L300P inverter is tripped.
Disabled
NviObjRequest have received a RQ_DISABLED request. Settings of
nviSpeedScale and nviSpeedStpt is disabled.
Manual_control
SJ300/L300P is not controlled from the option card.
See digital operator value at A001 (should be 02 to avoid manual control to be
set) and A002 (should be 01 to avoid manual control to be set). Manual_control
will be set if option-board isn’t in control over one parameter. Option card can
still give order where it has command.
It will be set if NviObjRequest have received a RQ_MANUAL_CTRL request.
Invalid ID
If another identification number then 0 and 1 have been set in request by SNVT
nviObjRequest. The request will not be carried out.
5.3.2 Drive Status (UNVT_sj300 nvoDrvStatus)
This output network variable provides the status of the drive.
The first three bytes will be mapped directly from the information received at address 0xFFFF8E10 in the
SJ300/L300P. If tripped, the last byte will contain an error code read from where pointer of last trip
(0x08000363) points too.
