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.
