Toshiba TOSVERT VF-FS1 Series instruction manual NviInvSetFreq Frequency Setpoint, LIU007Z LIU006Z

E6581373

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.)

nviInvSetFreq	nviDrvSpeedStpt		Operation
	value	state
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

nviRelay1, nviDigitalOut1,2		Command
value	state
N/A	0	Output OFF
0.0%	1
0.5 to 127.5%	1	Output ON
N/A	-1	Invalid

- Assignment

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

Variables		LIU007Z				LIU006Z
	Terminal		Parameter	Terminal			Parameter
nviDigitalOut1	---		---
					Under		Development
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.
