WIRING
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 one point on the
PLC. However, do not use common grounding with heavy electrical
systems.
• Make sure to properly wire to the European terminal board in accordance
with the following precautions.
Failure to do so may cause electric shock, a short-circuit, wire breakage, or
damage to the product.
- The disposal size of the cable end should follow the dimensions described
by the this manual.
- Tightening torque should follow the specifications by the this manual.
- Twist the end of strand wire and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires
of unspecified size.
- Affix the electric wires so that neither the terminal block nor the connected
parts are directly stressed.

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.
reverse rotation), and an interlock circuit (to prevent damage to the
equipment at the upper and lower positioning limits).
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
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
machinery operation in such a case.
3) Note that when an error occurs in a relay, triac or transistor output device, the
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.

• Do not bundle the control line together with or lay it close to the main circuit or

Automatic UP/DOWN
However, when on 1-phase 1-input mode, UP/
DOWN is determined below.
• Hardware UP/DOWN:
Up/down count is decided by OFF/ON of the A-
phase input terminal.
• Software UP/DOWN:
Up/down count is decided by the current value
(K0/K1) of BFM #1.
When 32-bit is specified:
-2,147,483,648 to +2,147,483,647
When 16-bit is specified: 0 to 65,535
(upper limit is set up by BFM #3, #2.)
Each output is set when the present value of the
counter matches with the compare value, and is
switched OFF by a reset command.
YH: Direct output processed by hardware.
YS: Software processed output with worst delay
time of 300µs.
Therefore, when the input frequency is 50 kHz,
there is a worst case delay of 15 input pulses.
