7.5 VSD Object Output Network Variables
This section describes VSD object output network variables that need supplemental explanations. For variables
not found in this section, refer to Section 7.3 "VSD Object."
(1) nv4 nvoDrvSpeed
This NV outputs the inverter's output frequency as a percentage of SCPT_nomFreq (Base frequency).
- Variable type: SNVT_lev_percent
- Data setting range: -163.840 to 163.830% (0.005% resolution)
- CPs for control of the affected network bandwidth: SCPT_maxSendTime, SCPT_minSendTime and
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)
(2) nv23 nvoDrvStatus
This NV outputs the current inverter status. The format of this NV is the same as that of the inverter's
communication function code M14.

BUSY - - RL ALM DEC ACC IL VL - NUV BRK INT EXT REV FWD
FWD, REV : Run forward, Run reverse IL : During output current limiting
EXT : During DC-braking (or Pre-exciting) ACC : During acceleration
INT : Inverter shutdown DEC : During deceleration
BRK : Braking ALM : Alarm relay output
NUV : DC link bus voltage established (0: Undervoltage) RL : Communication active
VL : Output voltage limiting BUSY : Busy in writing function codes
- Variable type: SNVT_state
- CPs for control of the affected network bandwidth: SCPT_maxSendTime and 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)
(3) nv33 nvoReadParamVal
This NV reads out data from the inverter's function code specified by nv10 nviReadParamCode.
For details about readout of function code data, refer to Section 7.6.1 "Reading from inverter's
function codes."
- Variable type: SNVT_count
- Data setting range: 0000 to FFFF (hexadecimal)
- CPs for control of the affected network bandwidth: SCPT_maxSendTime
- Output timing: At the input time of nv10 nviReadParamCode or at intervals specified by
SCPT_maxSendTime (if specified)
This NV is issued after input of nviReadParamCode, regardless of whether the data has been
changed or not.
