(6) nv11 nviWriteParaCode, nv12 nviWriteParamVal
Data contained in nv12 will be written into a function code specified by nv11.
For details about writing data, refer to Section 7.6.2 "Writing to inverter's function codes."
- Variable type:
SNVT_count
- Data setting range: 0000 to FFFF (hexadecimal)
- Default setting: 0000 (hexadecimal)
- CPs for control of the affected network bandwidth: None
(7) nv13 nviAOcmd
This NV outputs its value onto the inverter's analog output terminal [FMA/FMP/FMI] (same as universal
AO).
To terminal [FM1], the NV outputs 0 to 11 VDC or 4 to 20 mADC. To terminal [FM2], the NV outputs 0 to 11
VDC or 0 to 20 mADC. To terminal [FMA], the NV outputs 0 to 11 VDC or 4 to 20 mADC. To terminal [FMP],
it outputs a square wave pulse train prescribed by the inverter. For [FMI], it outputs 4 to 20 mADC.
This allows the inverter to work as an analog output device having a single channel, physical analog output.
For details about terminals [FMA] and [FMP] (or [FMI] and [FM2]), refer to the user's manual of an
inverter, "Wiring for control circuit terminals" and "Overview of Function Codes," F31 and F35.
- Variable type:
SNVT_lev_percent
- Data setting range: -163.840 to 163.830% (Valid range for inverter: 0.000 to 110.000%)
Setting 163.835% (invalid), for example, will be ignored so that the inverter runs with
the previous value.
- Default setting: 0.000%
- CPs for control of the affected network bandwidth: SCPT_maxRcvTime
To validate this NV entry on the inverter, either of the following settings is required.
For [FM1] or [FMA], inverter's function code F31 = 10
For [FM2] or [FMP] (or [FMI]), F35 = 10
It is possible to enable both [FM1] and [FM2] or [FMA] and [FMP], however, both terminals output
the same analog level signals.
(8) nv14 nviDOcmd_Y1, nv15 nviDOcmd_Y2
The nv14 or nv15 outputs its ON/OFF value onto inverter's digital output terminal [Y1] or [Y2], respectively
(same as universal DO). This allows the inverter's physical Y terminals to work as a 2-bit (max.) digital
output device.
For details about Y terminals, refer to the user's manual of an inverter, "Wiring for control circuit
terminals" and "Overview of Function Codes," E20 and E21.
- Variable type:
SNVT_switch
- Data setting range: value = 0.0 to 100.0%, state = 1, 0, -1
- Default settings:
value = 0.0%, state = 0
- CPs for control of the affected network bandwidth: SCPT_maxRcvTime
Do not use nviDOcmd_Y1 or nviDOcmd_Y2 as a bit array. This is because, in LONWORKS
communication, two or more variables are never output concurrently, so the interface card may
miss-fetch the bit array at the timing when the data gets validated on the inverter. Accordingly, the
inverter could receive it as unexpected data. To handle them as a bit array, read out S07 by the
function code readout feature.
To validate this NV entry on the inverter, either of the following settings is required.
For [Y1], inverter's function code E20 = 27
For [Y2], E21 = 27
