This User’s Manual explains the pulse train positioning control combined module. Read this manual carefully to ensure
correct operation.
When using modules or peripheral devices, be sure to read the corresponding user’s manuals listed below.
1. This manual may not be reproduced in whole or part in any form without prior written approval by the manufacturer.
2. The contents of this manual (including specifications) are subject to change without prior notice.
3. If you find any ambiguous or incorrect descriptions in this manual, please write them down (along with the manual
No. shown on the cover) and contact FUJI.
Be sure to read the “Safety Precautions” thoroughly before using the module.
Here, the safety precaution items are classified into “Warning” and “Caution.”
Safety Precautions
Warning
Caution
Even some items indicated by “Caution” may also result in a serious accident.
Both safety instruction categories provide important information. Be sure to strictly observe these instructions.
: Incorrect handling of the device may result in death or serious injury.
: Incorrect handling of the device may result in minor injury or physical damage.
Warning
◊ Never touch any part of charged circuits as terminals and exposed metal portion while the power is turned ON. It may
result in an electric shock to theoperator.
◊ Turn OFF the power before mounting, dismounting, wiring, maintaining or checking, otherwise, electric shock, erratic
operation or troubles might occur.
◊ Place the emergency stop circuit, interlock circuit or the like for safety outside the PC. A failure of PC might break or
cause problems to the machine.
◊ Do not connect in reverse polarity, charge (except rechargeable ones), disassemble, heat, throw in fire or short-circuit
the batteries, otherwise, they might burst or take fire.
◊ If batteries have any deformation, spilled fluids, or other abnormality, do not use them. The use of such batteries might
cause explosion or firing.
◊ Do not open the FG terminal with the LG-FG short circuited. (It must be grounded, otherwise it might cause electric
shock.)
Safety Precautions
Caution
◊ Do not use one found damaged or deformed when unpacked, otherwise, failure or erratic operation might be caused.
◊ Do not shock the product by dropping or tipping it over, otherwise, it might be damaged or troubled.
◊ Follow the directions of the operating instructions when mounting the product. If mounting is improper, the product
might drop or develop problems or erratic operations.
◊ Use the rated voltage and current mentioned in the operating instructions and manual. Use beyond the rated values
might cause fire, erratic operation or failure.
◊ Operate (keep) in the environment specified in the operating instructions and manual. High temperature, high humidity,
condensation, dust, corrosive gases, oil, organic solvents, excessive vibration or shock might cause electric shock, fire,
erratic operation or failure.
◊ Select a wire size to suit the applied voltage and carrying current. Tighten the wire terminals to the specified torque.
Inappropriate wiring or tightening might cause fire, malfunction, failure, or might cause the product to drop from its
mounting.
◊ Contaminants, wiring chips, iron powder or other foreign matter must not enter the device when installing it, otherwise,
erratic operation or failure might occur.
◊ Remove the dust-cover seals of modules after wiring, otherwise, fire, accidents, failure or fault might occur.
◊ Connect the ground terminal to the ground, otherwise, an erratic operation might occur.
◊ Periodically make sure the terminal screws and mounting screws are securely tightened.
Operation at a loosened status might cause fire or erratic operation.
◊ Put the furnished connector covers on unused connectors, otherwise, failure or erratic operation might occur.
◊ Install the furnished terminal cover on the terminal block, otherwise, electric shock or fire might occur.
◊ Sufficiently make sure of safety before program change, forced output, starting, stopping or anything else during a run.
The wrong operation might break or cause machine problems.
◊ Engage the loader connector in a correct orientation, otherwise, an erratic operation might occur.
◊ Before touching the PC, discharge any static electricity that may have been collected on your body. To discharge it,
touch a grounded metallic object. Static electricity might cause erratic operation or failure of the module.
◊ Be sure to install the electrical wiring correctly and securely, observing the operating instructions and manual. Wrong or
loose wiring might cause fire, accidents, or failure.
◊ When disengaging the plug from the outlet, do not pull the cord, otherwiase, break of cable might cause fire or failure.
◊ Do not attempt to change system configurations (such as installing or removing I/O modules) while the power is ON,
otherwise, failure or erratic operation might occur.
◊ Do not attemp to repair the module by yourself contact your Fuji Electric agent. When replacing the batteries, correctly
and securely connect the battery connectors, otherwise, fire, accidents or failure might occure.
◊ To clean the module, turn power off and wipe the module with a cloth moistened with warm water. Do not use thinner or
other organic solvents, as the module surface might become deformed or discolored.
◊ Do not remodel or disassemble the product, otherwise, a failure might occur.
◊ Follow the regulations of industrial wastes when the device is to be discarded.
◊ The modules covered in these operating instructions have not been designed or manufactured for use in equipment or
systems which, in the event of failure, can lead to loss of human life.
◊ If you intend to use the modules covered in these operating instructions for special applications, such as for nuclear
energy control, aerospace, medical, or transportation, please consult your Fuji Electric agent.
◊ Be sure to provide protective measures when using the module covered in these operating instructions in equipment
which, in the event of failure, may lead to loss of human life or other grave results.
◊ External power supply (such as 24V DC power supply) which is connected to DC I/O should be strongly isolated from
AC power supply.

Section 1 General
1-1 Precautions
The NP1F-MP1/NP1F-MP2 is a pulse train positioning control combined module which is connected to a CPU module via
an SX bus. It is used in combination with a pulse train input command-type servo amplifier + motor or with a stepping
motor driver to perform high-accuracy positioning. When the separate differential conversion unit (NP2F-LEV) is used, it
can be connected to differential I/O devices.
Precautions for using the NP1F-MP1/NP1F-MP2 are as follows:
(1) Handling precautions as precision device
1) Do not drop the device.
2) Avoid installing the device in places subject to strong vibrations.
3) Avoid installing the device in places where harmful gas (corrosive gas) exists.
4) Avoid installing the device within the same panel as high-tension (3000V or 6000V or more) devices.
5) Avoid sharing the same power supply with equipment which produces high noise (e.g. inverter).
6) Avoid using the device in places where the temperature is too high or low, or the humidity is too high.
Operating ambient temperature: 0 to 55°C
Operating ambient humidity : 20 to 95%RH
7) In places with extremely low humidity, excessive static electricity tends to build up. When you touch the NP1F-
MP1/NP1F-MP2 in such an environment, be sure to touch a metal ground in advance in order to discharge the
static electricity which is charged on your body.
(2) Precautions concerning operating conditions and environment
When the NP1F-MP1/NP1F-MP2 is used in the following conditions or environment, secure enough margin for the rated
specifications and functions (performance), take sufficient fail-safe measures, and be sure to consult with personnel at
your Fuji Electric sales office.
1) Storage or use in conditions or an environment which is not described in the operating instructions or user's
manual
2) Applications in nuclear power generation control, railways, aircraft, railcars, incinerator equipment, medical
facilities, amusement machines, safety devices, etc.
3) Applications where a great effect on human life or proper ty may be anticipated and a high degree safety is

Precaution:
• This module only contains the basic functions for positioning processing.
Motion-related functions (manual motion, original point return motion, interpolation, etc.) are processed by the
expansion FB (function block) which is integrated into the MICREX-SX series high-performance CPU module.
• When fail-soft operation needs to be set, be sure to use “1030” or later version of the high-performance or standard
CPU module and “2030” or later version of the positioning module.
