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
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 property may be anticipated and a high degree safety is
required
