(4) nv34 nvoAccessErrCode
After completion of writing of inverter's function code data with nv11 nviWriteParaCode and nv12
nviWriteParamVal, this NV outputs a three-byte string "Write error code (1 byte) + Function code accessed
(2 bytes)." If the data has been successfully written, the error code value is 00h.
For details about error codes, refer to Table 7-10 in Section 7.6.2 "Writing to inverter's function codes."
- Variable type: UNVT_ErrCode (3 bytes)
1 byte 1 byte 1 byte

LonMaker represents this NV data in the format: "Error code (decimal), Function code group
(decimal), Function code number (decimal)."
For details about the NV format and function code writing procedure, refer to Section 7.6.2 "Writing to
inverter's function codes."
- Data setting range: 00, 00, 00 to FF, FF, FF (hexadecimal)
- CPs for control of the affected network bandwidth: None
- Output timing: After the input time of nv12 nviWriteParamVal
(5) nv35 to nv37 nvoAIVal_1 to nvoAIVal_3
The nv35 to nv37 output the voltage or current input level applied to inverter's analog input terminals [12],
[C1] and [V2] in percentage, respectively. Table 7-7 lists the relationship between terminals and NVs.
Table 7-7 Analog input terminals and NVs
Network variables Analog terminals Analog signal level
nvoAIVal_1 [12] 0 to 100% = 0 to 10 V
nvoAIVal_2 [C1] 0 to 100% = 4 to 20 mA or 0 to 20
mA
nvoAIVal_3 [V2] 0 to 100% = 0 to 10 V
For details about terminals [12], [C1] and [V2], refer to the "Wiring for control circuit terminals" in the
Inverter User's Manual.
- Variable type: SNVT_lev_percent
- Data setting range: 0.000 to 100.000% (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)
The NV ignores bias and gain data for each analog input. On the LONWORKS network, the
following relationship is always established regardless of the bias and gain data: When 0 V (0 mA
or 4 mA) is applied to an analog input terminal, the NV value is 0%, and when 10 V (or 20 mA),
100%.
