Metasys N2 Set-Up
A Yaskawa Electric America, Inc. (YEA) representative is responsible for proper configuration of the drive for its primary application,
while a Johnson Controls, Inc. representative is responsible for field panel programming to make use of the drive’s functionality in the
building automation system as a VND device. As such, there must be coordination between the Yaskawa Electric America and Johnson
Controls representatives to ensure that the programming of the drive is consistent with the particular application requirements. After
verifying that the drive installation and wiring are correct, apply power to the drive. Table 1.1 below lists the parameters and their values
required for proper Metasys N2 communication and control.
