Check item
Action
Does the CPU module indicate any error?
If an error is indicated with the CPU module, refer to troubleshooting
on the user's manual for the CPU module used.
Is CH
Pulse measurement start command (Function input
terminal) (RY30, RY48) or CH
Pulse measurement start
command (Latch counter input terminal) (RY32, RY4A), the signal
corresponding to the terminal to be measured, turned on?
Turn on the signal corresponding to the terminal to be measured,
CH
Pulse measurement start command (Function input terminal)
(RY30, RY48) or CH
Pulse measurement start command (Latch
counter input terminal) (RY32, RY4A).
Are the external wirings to CH
Function input terminal (FUNC1,
FUNC2) and CH
Latch counter input terminal (LATCH1,
LATCH2) correct?
Check the external wiring and correct errors.

Measures
against
noise
Are the shielded twisted pair cables used for pulse
input wiring?
Use the shielded twisted pair cables for pulse input wiring.
Are measures against noise taken for the adjacent
devices and inside the control panel?
Take noise reduction measures such as attaching a CR surge
suppressor to the magnet switch.
Is the distance between the high voltage equipment
and pulse input line kept enough?
Bundle up the pulse input lines in a single tube, and keep a distance of
150mm or more between the pulse input lines and the power line even
inside the control panel.
Does any noise come from the grounded part of the
high-speed counter module?
Separate the grounding cable of the high-speed counter module from
the grounded part.
If the case of the high-speed counter module touches the grounded
part, separate it.
Does a program used read out the 2-word data such as a
measured pulse value in unit of 2 words (32 bits)?
Read out it in unit of 2 words (32 bits).
