6.5.4. nviInvSetFreq (Frequency Setpoint)
Input network variable
SNVT type: SNVT_freq_hz (76)
It provides speed setpoint in Hz. The rotation direction is provided by “nviDrvSpeedScale” (Negative
value means in reverse).
- Valid range: 0.0 Hz to the maximum vale in the inverter.
(Refer to the inverter instruction manual for details.)
nviDrvSpeedStpt
nviInvSetFreq
value state
Operation
N/A N/A 0 Stop
3276.7 Hz value 1 Drive at the speed provided by “nviDrvSpeedStpt”
0.0 to 3276.6 Hz N/A 1 Drive at the speed provided by “nviInvSetFreq”
Setpoint by “nviInvSetFreq” is limited by value of “nciMaxSpeed” and “nciMinSpeed”.
- Unit: 0.1Hz
- Default value: 3276.7Hz (In this case, nviDrvSpeedStpt enables to provide the setpoint)
Default value will be adopted at power-up and in case of not receiving an update of “nviSpeedStpt”,
“nviDrvSpeedScale” or “nviInvSetFreq” within the specified Receive Heartbeat time (nciRcvHrtBt).
6.5.5. nviRelay1 /nviDigitalOut1,2 (Control of Digital Output)
Input network variable
SNVT type: SNVT_switch (95)
They enable a command of the Relays and Logic outputs on the inverter if they are assigned.
- Valid range

If these variables are used, the inverter parameters must be set as follows.

Variables
Terminal Parameter Terminal Parameter
nviDigitalOut1 --- ---
nviDigitalOut2 --- ---
nviRelay1 FL F132 = 38
If multiple digital output control signals are used at the same time, the output value is the OR of all digital
output controls.
6.5.6. nviDigitalOutput (Control of All Digital Outputs)
Input network variable (Reserved)
SNVT type: SNVT_state (83)
This variable enables the command of all the Relays and Logic outputs of the inverter if they are
assigned.
