(6) nv38 nvoPIDFb
When the PID feedback value is assigned to any of analog input terminals [12], [C1] and [V2], this NV
outputs the analog signal level applied to that terminal as the PID feedback value in percentage.
To use this NV, it is necessary to enable the inverter's PID control. For details about the PID control of
the inverter, refer to the "J codes" and "PID Control Block" given in the Inverter User's Manual.
- Variable type: SNVT_lev_percent
- Data setting range: 0.0 to 163.830% (0.005% resolution)
- CPs for control of the affected network bandwidth: SCPT_maxSendTime, SCPT_minSendTime,
SCPT_minDeltaLevel
- Output timing: At the time of data change, at intervals specified by SCPT_maxSendTime (if specified),
after the time specified by SCPT_minSendTime (if specified), or when the data change
rate exceeds the value specified by SCPT_minDeltaLevel (if specified)
This NV data can be adjusted with analog input gain setting. The related inverter's function codes
are C32, C34, C37, C39, C42 and C44.
(7) nv39, nv40, nv41, nv43 nvoYstatus_1, nvoYstatus_2, nvoYstatus_3, nvoYstatus_5
The nv39 to nv41 and nv43 output the ON/OFF status of inverter's digital output terminals [Y1] to [Y3] and
relay contact output terminal [5A/C], respectively. Signal assignments to these terminals are made with
function codes E20 to E22 and E24.
For details about function codes E20, E21, E22 and E24, refer to the user's manual of an inverter,
"FUNCTION CODES."
- Variable type: SNVT_switch
- Data setting range: value = 0.0, 100.0%, state = 1, 0
- CPs for control of the affected network bandwidth: SCPT_maxSendTime, SCPT_minSendTime
- Output timing: At the time of data change, at intervals specified by SCPT_maxSendTime (if specified) or
after the time specified by SCPT_minSendTime (if specified)
Although the nv42 nvoYstatus_4 exists, it does not function since the Inverter does not support
terminal [Y4].
(8) nv44 to nv48 nvoXstatus_1 to nvoXstatus_5
The nv44 to nv48 check whether terminal commands applied to inverter's digital input terminals [X1] to [X9]
are validated or not on the inverter, respectively, and outputs it in ON/OFF state.
Setting data "0" to inverter's function code y98 or UCPT_LinkFunc makes it possible to monitor
the validation status of terminal commands applied to physical terminals [Xn], respectively. In this
situation, it is also possible to monitor commands assigned by nviXcmd_1 to nviXcmd_5 as well.
For details, refer to the RS-485 Communication User's Manual (MEH448), Chapter 5, Section
5.1.2 [3] "Operation command data."
- Variable type: SNVT_switch
- Data setting range: value = 0.0, 100.0%, state = 1, 0
- CPs for control of the affected network bandwidth: SCPT_maxSendTime, SCPT_minSendTime
- Output timing: At the time of data change, at intervals specified by SCPT_maxSendTime (if specified) or
after the time specified by SCPT_minSendTime (if specified)
Assigning "Universal DI" to a digital input terminal (E01 to E05 = 25) makes it possible to output
the physical ON/OFF status of terminal [Xn] onto the LONWORKS network. Accordingly, the
inverter's physical terminal [Xn] can be used as a digital input device having max. 5 bits.
