3 Safety Information
3.1 About this manual
Read carefully this chapter to raise your awareness of potential risks and hazards when working with the
Neptune Servo Drive.
To ensure maximum safety in operating the Neptune Servo Drive, it is essential to follow the procedures
included in this guide. This information is provided to protect users and their working area when using the
Neptune Servo Drive, as well as other hardware that may be connected to it. Please read this chapter carefully
before starting the installation process.
3.2 Warnings
The following statements should be considered to avoid serious injury to those individuals performing the
procedures and/or damage to the equipment:
•To prevent the formation of electric arcs, as well as dangers to personnel and electrical contacts, never
connect/disconnect the Neptune Servo Drive while the power supply is on.
•Disconnect the Neptune Servo Drive from all power sources before proceeding with any possible wiring
change.
•After turning off the power and disconnecting the equipment power source, wait at least 10 seconds
before touching any parts of the controller that are electrically charged or hot.
3.3 Precautions
The following statements should be considered to avoid serious injury to those individuals performing the
procedures and/or damage to the equipment:
•The Neptune Servo Drive components temperature may exceed 100 ºC during operation.
•Some components become electrically charged during and after operation.
•The power supply connected to this controller should comply with the parameters specified in this
document.
• When connecting the Neptune Servo Drive to an approvedpower source, do so through a line that is
separate from any possible dangerous voltages, using the necessary insulation in accordance with safety
standards.
•High-performance motion control equipment can move rapidly with very high forces. Unexpected
motion may occur especially during product commissioning. Keep clear of any operational machinery
and never touch them while they are working.
•Do not make any connections to any internal circuitry. Only connections to designated connectors are
allowed.
•All service and maintenance must be performed by qualified personnel.
•Before turning on the Neptune Servo Drive, check that all safety precautions have been followed, as well
as the installation procedures.

INGENIA |05/29/2017 8
4 Product Description
Neptune is a high performance closed loop servo drive controller suitable for DC brushed, voice coils and
brushless motors.
Its compact design (40 mm x 40 mm) includes CANopen/EtherCAT, RS-232 and USB communication ports,
enabling thus a wide choice of interfacing methods. Its extended nominal voltage range from 9 V to 48 V with a
single supply and current up to 2.5 A continuous allows its use in several applications, and the small footprint
and the needless of an external heatsink allow the controller to be a valid OEM for critical-size applications.
The Neptune Digital Servo Drive has been designed with efficiency in mind. It incorporates cutting-edge
MOSFET technology as well as optimized control algorithms to provide the perfect trade-off between EMIs and
efficiency. In addition its ultra-low PWM deadtime (<10 ns) provides great control stability in velocity and
position applications.
Neptune Servo Drive is provided with several general purpose inputs and outputs for with 5V TTL levels and
tolerant to 24 V PLC. They are fully protected against short circuits and overvoltage and can be interfaced in
industrial environments. By using these inputs and outputs it is possible to implement alarm signals, connect
digital sensors, activate external devices (motor brake, LEDs, actuators, solenoids, etc.).Some of the digital and
analog inputs can also be used as command / target sources.
Neptune includes many passive and active protections to ensure its safe operation and easy integration.
