The LonWorks card converts LonWorks commands to CiA402 commands.A "Run" command from LonWorks in converted to a CiA 402 "Operation enable" command.A "Stop" command from LonWorks is converted to a "Shutdown" command. If the drive is running, a "Halt" command is first applied.Note:The network variable nviInvSetFreq permits the control of the drive by a frequency setpoint instead of percentage.b Drive Speed Setpoint Scaling (nviDrvSpeedScale)This input network variable provides scaling for nviDrvSpeedStpt.Negative values indicate a motor direction in reverse.For example, if the nviDrvSpeedStpt value is 50% and nviDrvSpeedScale is -150%, then the actual speed setpoint is -75%, or 0.75 timesthe nominal speed in the reverse direction.NameSNVT referenceSNVT index 81Unit 0.005%nviDrvSpeedScaleSNVT_lev_percentRange -163.840% ... 163.830%0x7FFF = +163.835%: invalid valueDefinitionDrive Speed Setpoint ScalingDefault value is determined by nciDrvSpeedScale.
