4.5. Input network variables

4.5.1. nviDrvSpeedStpt

(Drive Speed Setpoint)

SNVT type: SNVT_switch (95)

It provides start/stop control and a low resolution speed setpoint as a percentage of nominal speed.

Output frequency = “nciNmlFreq” x “nviDrvSpeedStpt.value” x “nviDrvSpeedScale”

- Valid range

nviDrvSpeedStpt

value state

Operation

N/A

-1

Invalid (default value)

N/A 0

Stop

0.0 to 100.0%

Drive at the speed from 0.5% to 100%

100.5 to 127.5%

Drive at 100% speed

Unit (nviDrvSpeedStpt.value): 0.5%

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

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.

4.5.2. nviDrvSpeedScale

(Drive Speed Setpoint Scaling)

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.

4.5.3. 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 500 Hz

- 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).
