Ndrive FCL Hardware Manual
Installation and Configuration
2.6. Encoder Input (TB103 A/B)
The Ndrive FCL is equipped with two auxiliary encoder input channels that are accessible through
TB103A/B. The encoder interfaces accept an RS-422 differential line driver.
The auxiliary encoder input channels cannot be used for closing the position loop. They are intended to be
used with the Infinite Field of View and the Marking on the Fly functionality of the Ndrive FCL.
