SED2 VFD LON Interface Option Operating Instructions LON Interface Option Overview General Description The LONMark® certified SED2 VFD LON Interface Option provides direct digital control of SED2 Variable Frequency Drives (VFDs). The SED2 VFD can reside on a LONWorks® network, enabling information sharing with all other LONMark products from multiple vendors. The SED2 VFD LON Interface Option is LONMark-compliant with Variable Speed Motor Drive Functional Profile Number 6010.
LON Interface Option Overview LON Interface Option Functionality The foundation of the SED2 VFD LON Interface Option is a Neuron 3120 processor, which manages the LON software functionality. The LON software functionality is based on LONMark Functional Profile Number 6010 for Variable Speed Motor Drives. In addition to the Standard Network Variable Types (SNVTs) of this Functional Profile, several others have been added: • Two sets of inputs were added for feedback and setpoint.

SED2 VFD LON Interface Option Operating Instructions Installation and Wiring SED2 VFD Frame Sizes A, B, and C WARNING: Make sure that the SED2 VFD is de-energized (off) before you install or remove the LON Interface Option. 1. Remove the SED2 VFD operator panel. 2. Install LON Interface on the SED2 VFD I/O module (Figure 4) by inserting two bottom guides into appropriate slots at the sides of the I/O module and pushing the upper section inward until the locking mechanism latches. 3.
Installation and Wiring SED2 VFD Frame Sizes D, E, and F WARNING: Make sure that the SED2 VFD is de-energized (off) before you install or remove the LON Interface Option. 6. Terminate end of network cable with a single, two-pin, female LonWorks FTT-10A connector. 7. Attach network cable FTT-10A connector to connector at bottom of Lon Interface (Figure 5 and 7). 8. Reinstall bottom cover, side cover, and the SED2 VFD operator panel.
SED2 VFD LON Interface Option Operating Instructions Installation and Wiring Notes WARNING: A VFD can be switched on unintentionally if the serial bus installation is not operated correctly. The bus must be started by personnel who are qualified and trained in installing systems of this type. 1. DIP Switch Leave DIP switches OFF for proper operation of the LON Interface Option. 2. WIRING Wiring must conform to local codes and ordinances. 3. WIRE ROUTING Maintain a minimum of 5 ft (1.
Startup Procedures Startup Procedures Setting Up SED2 VFD Parameters See SED2 VFD Operation & Maintenance Manual (Document No. 125-3202) for procedures to commission and start up the SED2 VFD. Table 1 lists the SED2 parameter settings that are required for correct communications and control of the SED2 VFD with a LON Interface Option. CAUTION: Changes made to the parameters other than what is listed in Table 1 can result in damaging the drive or building equipment. Table 1.
SED2 VFD LON Interface Option Operating Instructions Verifying Parameter Operations After setting VFD parameters, perform the following steps to verify parameter operations using the drive keypad: Step Press Action Displays r0000. 1 2 and Enables scrolling to the appropriate parameter number. Displays the value of the selected parameter. 3 4 and Enables scrolling to the appropriate parameter value. Confirms parameter value setting and enables scrolling to other parameter numbers.
