6.5. Input network variables

6.5.1. nviDrvSpeedStpt (Drive Speed Setpoint)

Input network variable, Variable Speed Drive 6010_11 (Mandatory) SNVT type: SNVT_switch (95)

It provides start/stop control and a low resolution speed setpoint as a percent of nominal speed. Output frequency = “nciNmlFreq” x “nviDrvSpeedStpt.value” x “nviDrvSpeedScale”

- Valid range

	nviDrvSpeedStpt		Operation
	value	state	Operation
	value	state
	N/A	0	Stop
	0.0 to 100.0%	1	Drive at the speed from 0.5% to 100%
	100.5 to 127.5%	1	Drive at 100% speed
	N/A	-1	AUTO (Invalid)

- Unit (nviDrvSpeedStpt.value): 0.5%

- Default value: 0.0% (value), AUTO (state = -1),

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). Speed reference set by “nviInvSetFreq” will override “nviDrvSpeedStpt” (refer to “nviInvSetFreq”).

N.B. The value exceeded to the inverter setpoint resolution will be rounded.

6.5.2. nviDrvSpeedScale (Drive Speed Setpoint Scaling)

Input network variable, Variable Speed Drive 6010_11 (Optional) SNVT type: SNVT_lev_percent (81)

This input network variable provides scaling for “nviDrvSpeedStpt”. Negative values indicate a motor direction in reverse.

-Valid range: -163.840 to 163.830%

-Unit: 0.005%

-Default value: “nciDrvSpeedScale”

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).

N.B. The value exceeded to the inverter setpoint resolution will be rounded.

6.5.3. nviResetFault (Fault Reset Command)

Input network variable

SNVT type: SNVT_switch (95)

This command clears the inverter fault when the inverter is under a fault that can be cleared. - Valid range

nviResetFault			Command
value		state

N/A		0, -1	Invalid
0.0%		1

0.5% to 127.5%		1	Clear a fault and reset the inverter.
