ENGLISH
Depending on the command assignment to inverter's digital input terminals, some ON/OFF
commands via the LONWORKS network using these NVs may be ignored. On the other hand,
some commands entered from the terminal block may be unconditionally validated. For details
about these events, refer to the RS-485 Communication User's Manual (MEH448), Chapter 5,
Section 5.1.2 [3] "Operation command data."
(9) nv50 nvoAlarm
This NV outputs the contents of an alarm that is occurring or has recently occurred.
- Variable type: UNVT_alarm_cod (1 byte, decimal)
- Data setting range: 0 to 255
- CPs for control of the affected network bandwidth: SCPT_minSendTime
- Output timing: At the time of data change or after the time specified by SCPT_minSendTime (if
specified)
