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
