NOTE:
The function of terminals TB-10A, TB-10B, TB-13A, TB-13B, TB-13C, TB-
13D, TB-14, TB-15, TB-16 and TB-18 are dependent on the programming
of certain parameters. In most cases, the name of the parameter matches
the number of the terminal, allowing quick and easy programming of the
terminals to suit the application. The exception is TB-16 and TB-18, which
are governed by Parameter 54 - RELAY.
A complete description of operating the drive in the AUTO mode can be found in Section
14.2. The following diagrams provide a quick reference to wire the drive for the most
common configurations.
