Setting P.061 = 1 provides full drive control from the network. Any drive data that has been assigned a network register is transferred over the network. Parameter P.
P.062 Option Port: Communication Loss Response (continued) If P.062 = 0 The drive will consider a loss of network communication to be a drive fault, resulting in an IET-type stop sequence. When P.062 is set to IET fault (0) and communication is lost: • The drive latches a fault condition and performs a coast stop. • The network communication loss fault is generated (nCL is displayed). • The front panel REMOTE LED blinks, indicating that the network is inactive.
P.062 Option Port: Communication Loss Response (continued) If P.062 = 2 The drive gets its speed/torque reference from the terminal strip analog input and its stop input from the terminal strip stop input. All other inputs are held at the last values received from the network. This allows the network to continue controlling the drive reference with a direct-wired analog output to input, and to stop the drive with a direct-wired digital output to input. Note that if P.
6.4 Setting the Speed Display Scale (P.028) Parameter Range: 10 to 9999 Default Setting: Synchronous speed based on H.001 (assuming a 4-pole motor) Parameter Type: Tunable Parameter P.028 (Speed Display Scaling) defines the scaling value applied to the manual reference, the selected speed reference, and the output speed displays. P.028 must be set to 100 for nvoDriveSpeed to show the correct percent of nominal speed. This value is written by the LonWorks board at start up.

CHAPTER 7 Operating the Drive Using a LonMark Profile A LonMark profile defines the functional profile for a node communicating with other nodes. The profile specifies which SNVTs (Standard Network Variable Types) and SCPTs (Standard Configuration Property Types) are used, and provides a semantic meaning about the information being communicated. When a profile is implemented in a node, it’s called a LonMark object. One node can have several objects implemented.
