PRECAUTIONS
Make sure to observe the following precautions in order to prevent any
damage to the machinery or accidents due to abnormal data written to the
PLC under the influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main
circuit, high-voltage line or load line. Otherwise, noise disturbance and/or
surge induction are likely to take place. As a guideline, lay the control line at
least 100mm (3.94") or more away from the main circuit or high-voltage lines.
2) Ground the shield wire or shield of the shielded cable at two points; on the
PLC and the device on other end. However, do not use common grounding
with heavy electrical systems.
3.1 Connection to input/output connector
The input and output connectors conform to the MIL-C-83503.
For the input and output connectors pin assignment, refer to section 1.4.
1) Compliant connectors (commercially available connectors)
Use a 40-pin (1-key) socket connector conforming to MIL-C-83503.
Confirm in advance that the connectors do not interfere with other parts
including connector covers.
2) Connectors for user-made input/output cables (available from Mitsubishi)
Users should provide electric wires and a pressure bonding tool.

Compliance with EC directive (CE Marking)
This note does not guarantee that an entire mechanical module produced in
accordance with the contents of this note will comply with the following standards.
Compliance to EMC directive and LVD directive for the entire mechanical module
should be checked by the user / manufacturer. For more details please contact the
local Mitsubishi Electric sales site.
Requirement for Compliance with EMC directive
The following products have shown compliance through direct testing (of the identified
standards below) and design analysis (through the creation of a technical construction
file) to the European Directive for Electromagnetic Compatibility (2014/30/EU) when
used as directed by the appropriate documentation.

Installation in Enclosure
Programmable controllers are open-type devices that must be installed and used
within conductive control cabinets. Please use the programmable controller while
installed within a conductive shielded control cabinet. Please secure the cabinet
door to the control cabinet (for conduction). Installation within a control cabinet
greatly affects the safety of the system and aids in shielding noise from the
programmable controller.

may
Differential-Line-Driver (AM26C31 or equivalent) and open collector output
encoders are available for the FX
3U
-2HC.
The FX
-2HC has two outputs per channel. When the counter value coincides with
3U
an output compare value, the appropriate output is set ON. The output transistors
are individually isolated to allow either sink or source connection methods.
Various counter modes, such as 1-phase or 2-phase, 16-bit or 32-bit modes, can be
selected using commands in the sequence program. Allow the FX
run only after setting these mode parameters.

DESIGN
PRECAUTIONS
Make sure to have the following safety circuits outside of the PLC to ensure safe
system operation even during external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop circuit, a protection
circuit, an interlock circuit for opposite movements (such as normal vs.
Encoder
reverse rotation), and an interlock circuit (to prevent damage to the
equipment at the upper and lower positioning limits).
+5V
2) Note that when the PLC CPU detects an error, such as a watchdog timer
error, during self-diagnosis, all outputs are turned off. Also, when an error that
0V
cannot be detected by the PLC CPU occurs in an input/output control block,
output control may be disabled.
External circuits and mechanisms should be designed to ensure safe
LA
machinery operation in such a case.
3) Note that when an error occurs in a relay, triac or transistor output device, the
LAR
output could be held either on or off.
For output signals that may lead to serious accidents, external circuits and

mechanisms should be designed to ensure safe machinery operation in such
a case.
