3.4.8. I/O Cables
The Tuba has three I/O ports (ANALOG INPUTS, DIGITAL INPUTS and DIGITAL OUTPUTS) which
can be used to connect 2 analog inputs, 10 separate digital inputs and 6 separate digital
outputs:

3.4.8.1. Analog Inputs
The Tuba servo drive is equipped with two differential, freely-programmable analog inputs. The
ANALOG INPUTS port has a 9-pin D-Sub socket. When assembling an I/O cable for analog input
follow the instructions in Section 3.4.4 (Feedback and Control Cable Assemblies) using a 9-pin
D-Sub plug with a metal case.
Note: Analog Inputs 1 and 2 are functionally identical. However, note that the velocity and
current commands can only be given on Analog Input 1.
The pins are described below.
