7.6.1 Network communication interface
Nix Servo Drive can utilize network communication as a form of input command. Supported network interfaces for
Nix Servo drive are CAN (CANopen protocol), USB, RS-485 and EtherCAT.
USB interface is not suitable for long distances or noisy environments. This protocol is only recommended for
configuration purposes.
For normal operation, it is suggested to use CAN, RS-485 or EtherCAT. These interfaces are more robust against
noise than USB, and allow higher distances between the Nix Servo Drive and the commander. These command
sources can be used for setting position, velocity or torque target.

7.6.2 Standalone
Nix Servo Drive is provided with an internal non-volatile memory where a standalone program can be saved. With
the use of Ingenia
suite, the user can configure and save instructions to this 1 Mb (128K x 8bit) EEPROM,
allowing Nix Servo Drive to work in standalone mode. In this mode, there is no need of any external command
source.
Programs or macros composed with Motion Lab suite allow to
configure position, velocity or torque targets
and
to
interface with general purpose inputs and outputs.
This feature can be very useful in applications such as production lines or test equipment, where repetitive
movements are usual. Please refer to
7.6.3 Analog input
Position, velocity or torque targets can also be controlled trough an analog signal. Any general purpose analog
input can be used as command source. Nix Servo Drive has two 12-bit analog inputs, a single ended one with 0 V to
5 V range (AN_IN1) and a differential one with +/-10 V range (AN_IN2). Refer to I/O Connections for further details
about analog inputs.
A common application of the analog command source is the use of joysticks (or other kinds of potentiometers) for
controlling the position or velocity of a system. As application examples, the following figures show how to connect
a potentiometer to the single ended analog input (AN_IN1) and a dual track potentiometer to the differential
analog input (AN_IN2).
As an application example, the next picture shows how to connect a dual track potentiometer to get a ±10 V
differential input.
