Toshiba TOSVERT VF-FS1 Series NciRcvHrtBt Receive Heartbeat Time, NciSndHrtBt Send Heartbeat Time

Page 21

E6581373

6.4.3. nciRcvHrtBt (Receive Heartbeat Time)

Configuration property, Variable Speed Drive 6010_11 (Optional) SNVT type: SNVT_time_sec (107)

SCPT reference: SCPTmaxRcvTime (48)

It is used to control the maximum period of time that elapses after the last update of the network variables (“nviDrvSpeedStpt”, ”nviDrvSpeedScale”, “nviInvSetFreq”) before detecting the network malfunction and initializing the command and setpoint values. Refer to “7.4:Communication health management” for the inverter behavior in that case.

-Valid range: 0.0 to 6553.4 sec

-Unit: 0.1s

-Default value: 0.0s

A value of 0.0 sec disables the Receive Heartbeat mechanism.

Danger

Mandatory

Set up “nciRcvHrtBt” to stop the inverter when the option unit is deactivated by an unusual event such as tripping, an operating error, power outage, failure, etc. Deactivated option unit may cause an accident, if the “nciRcvHrtBt” is not properly set up.

6.4.4. nciSndHrtBt (Send Heartbeat Time)

Configuration property, Variable Speed Drive 6010_11 (Mandatory) SNVT type: SNVT_time_sec (107)

SCPT reference: SCPTmaxSendTime (49)

It defines the maximum period of time that expires before the network variables specified for heartbeat in some monitor values will automatically be updated. This timer restarts to count just after sending network variables. Refer to “7.4:Communication health management” for details.

-Valid range: 0.0 to 6553.4 sec

-Unit: 0.1s

-Default value: 0.0s

A value of 0.0sec disables the automatic update.

6.4.5. nciMinOutTm (Minimum Send Time)

Configuration property, Variable Speed Drive 6010_11 (Optional) SNVT type: SNVT_time_sec (107)

SCPT reference: SCPTminSendTime (52)

It defines the minimum period of time between automatic network variable transmissions. This function is prior to “nciSndHrtBt”. This timer starts to count just after sending the last variable. Refer to “7.4:Communication health management” for details.

-Valid range: 0.0 to 6553.4 sec

-Unit: 0.1s

-Default value: 0.5s

Setting 0.0sec disables transmission limitation.
