Foreword
Thank you for choosing the SPS-NE series servo drive manufactured by Megmeet.
SPS-NE servo drive, developed on a new hardware platform and featured with excellent performance, fully-fledged
functions, compact structure, simple installation, easy commissioning and maintenance, is an ideal product with
favorable price-performance ratio in the servo drive market for both general purposes and OEM.
SPS-NE servo drive adopts Ethernet communication interface, supports EtherCAT communication protocol, and
realizes networked operation of single servo drive or multiple servo drives in cooperation with the host controller. It
can be applied in machine tool feed shafts, printing, textile, cutting, manipulators, punch presses, semiconductor
welding machines and so on, achieving fast and accurate control on position, speed and torque.
This manual provides instructions and precautions for wiring, parameter setting, fault diagnosis and troubleshooting.
In order to ensure the correct installation and operation of the SPS-NE series servo drive, and to unlock its full
potential, please read this manual carefully before installation, keep the manual properly and give it to the actual
user when necessary.
Unboxing inspection
When you unbox the product, remember to check the following:
whether there is any damage on the drive;
whether the rated values on the nameplate are the same as what you ordered;
whether the included wires are intact and can be connected for use.
Our company has implemented strict inspection on the product’s manufacturing and packaging. If there is still any
error, please contact us or the local distributor.
We are engaged in the continuous improvement of drives. The relevant manuals provided by us are subject to
change without notice.

Safety precautions
Indicates that failure to comply with the notice can result in death or severe personal injuries.
Indicates that failure to comply with the notice may result in moderate or minor personal injuries
or equipment damage.
Install the product on incombustible materials such as metal. Failure to comply will result in a fire.
Do not install the product near combustible objects. Failure to comply will result in a fire.
Do not install the product in places with explosive gases. Otherwise, there will be an explosion.
The wiring work must be done by professional personnel. Otherwise, there will be an electric shock.
Before wiring, check that the main and control power supplies are cut off. Otherwise, there will be an electric
shock.
Properly connect the grounding terminal of the drive. Otherwise, there will be an electric shock.
Properly close the cover before power-on. Otherwise, electric shock or explosion may occur.
When powering on a drive that has been stored for 2 years, use a voltage regulator to increase voltage
gradually. Otherwise, electric shock or explosion may occur.
To avoid electric shock, do not touch terminals when the drive is powered on.
To avoid electric shock, do not operate the drive with wet hands.
Before conducting maintenance, ensure that the power is cut off for 10 minutes, and check that the charging
indicator is completely off or the voltage of bus negative/positive is below 36 V. Failure to comply will result in
an electric shock.
Only professional personnel is qualified to replace the components. Do not leave any wire or metal parts inside
the drive. Failure to comply will result in a fire.
The bare parts of the terminal lugs in the main circuit must be wrapped with insulation tape. Otherwise,
electric shock may occur.

4
Install the product on the place that can bear the weight. Failure to comply will result in personal injuries or
equipment damage.
Do not install the drive near water pipes or other places with water splash. Otherwise, there will be equipment
damage.
Take care not to drop screws, gaskets, metal bars and the like into the drive. Otherwise, fire and equipment
damage may occur.
If the drive is damaged or lack of components, do not run the drive. Failure to comply will result in a fire or
personal injuries.
Do not install the product in the place exposed to direct sunlight. Otherwise, there will be equipment damage.
Cable lugs must be firmly connected to main circuit terminals. Otherwise, there will be equipment damage.
Do not install the servo drive in places with vibration beyond the specification. Otherwise, there will be
equipment damage.
