Network configuration variablesnciMaxSpeedThis configuration property is used to define the maximum speed of a motor. The value is entered as apercentage of nominal speed in RPM, as defined by the Nominal Speed (nciNmlSpeed) configurationvalue. The value of the maximum speed must be validated against the value of the minimum speed asfollows:-163.840 < minimum speed < maximum speed < 163.830nciMinSpeedThis configuration property is used to define the minimum speed of the motor. The value is entered asa percentage of nominal speed in RPM, as defined by the Nominal Speed (nciNmlSpeed) configurationvalue. The value of the minimum speed must be validated against the value of the maximum speed asfollows:-163.840 < minimum speed < maximum speed < 163.830nciRcvHrtBtThis configuration property is used to control the maximum time that elapses after the last update ofthe network variables nviDrvSpeedStpt or nviDrvSpeedScale before the VSD object starts to use thedefault values.nciSndHrtBtThis configuration property defines the maximum period that expires before the network variablesnvoDrvSpeed, nvoDrvCurnt and nvoDrvPwr are automatically updated.Archived Document
