Precautions
• After the reset is complete and 'CH1 Counter reset request' (Un\G386) is set to No reset request (0), input pulses are
invalid for a maximum of 20ms.
• If 'CH1 Preset setting value for accumulating count value' (Un\G384, Un\G385) is set to a value outside the setting range
and 'CH1 Counter reset request' (Un\G386) is set to Reset request (1), a preset setting value for accumulating count value
setting error (error code: 1920H) occurs. In this situation, 'CH1 counter reset request' (Un\G386) is set to No reset request
(0), but the count operation continues without resetting any of the count values. To reset each of the count values again,
turn on and off 'CH1 Error reset request' (Y8), and then reset 'CH1 Preset setting value for accumulating count value'
(Un\G384, Un\G385) to a value within the setting range. Then, set 'CH1 Counter reset request' (Un\G386) to Reset request
(1).
