(RWr16 to RWr17, RWr2E to RWr2F), and continues to count.
*3 Keeps its normal operation unless an error occurs.
*4 The ring counter function does not start counting.
*5 The linear counter function stops counting.
*6 Compares the count value with the normal setting value just before the error. The error does not affect Coincidence
output assigned to the error CH and the other functions.
*7 Does not execute the cam switch function. The error does not affect the other functions.
*8 Executes the sampling counter function or periodic pulse counter function with the normal setting value just before the
error.
*9 Does not start to measure the frequency.
*10 Does not start to measure the rotation speed.
*11 Stops measuring pulses.
*12 Does not output the PWM waveform.
*13 Stops operations except the one on the error and updating EQU1 to EQU4 terminal status (RWr1), Cam switch output
signal (RWr2), Cam switch output terminal status (RWr3), CH Status (RWr20, RWr38), and CH External input status
(RWr21, RWr39).
*14 Continues its operation although the external output terminals of the extension output module are forced off. (Y0 LED to
YF LED on the extension output module turn on or off depending on the output status.)
*15 A minor error which can be reset by turning off then on CH Error reset command (RY36, RY4E)

CHAPTER 11 TROUBLESHOOTING
Action
Set CH Latch counter input
response time setting (address:
0129 .b4 to b5, 0149 .b4 to
H H
b5) to a value between 00b and
10b, and turn off then on Initial
data setting request flag (RY9).
• Malfunction due to noise may
be the cause. Check the
cable distance or grounding
condition of each device.
Then take measures against
noise.
• Conduct the unit test. If the
same error occurs again, a
hardware failure of the
module may be the cause.
Please consult your local
Mitsubishi representative.
