4.6.7. nvoInvOutFreq (Frequency Feedback)

SNVT type: SNVT_freq_hz (76)
It provides the inverter output frequency.
- Valid range: 0.0Hz to 500.0Hz
- Unit: 0.1Hz

4.6.8. nvoDrvSpeedOtpt (Inverter drive status)

SNVT type: SNVT_switch (95)
It provides Stopped / Running status and low resolution output speed of the motor.
- Specification
nvoDrvFeedback
value
N/A
0.0 to 127.5%
N.B.: It is not deal with the speed that exceeds the 127.5%.
The value exceeded to the resolution will be rounded.

4.6.9. nvoEmergStatus (Emergency Status)

SNVT type: SNVT_have_emerg (103)
It provides the response against an emergency stop of the inverter (nviEmergOverride). When the
node received "nviEmergOverride" network variable, it propagates the information to the network.

4.6.10. nvoDrvAlarm (Alarm)

SNVT type: SNVT_switch (95)
It provides the inverter fault.

Fault code
*1: Lower 7bits show the inverter fault code. As the fault code may be indicated in 0.5% unit on
network tool, correct value is twice value as it. 8th bit shows the communication error between
the inverter and the option (including RS485 port connection, "1" means abnormal.).
<Example>
In under emergency stop, the fault code of the inverter is set to 0x11 (the method of decimal
numeral 17). It is displayed as 17x0.5%=8.5%. When communication is in abnormal state, it
is set to 128 because the 8th bit is set to 1, and its value is set to 128x0.5%=64%.
