Setting 'CH1 Counter reset request' (Un\G386) to Reset request (1) changes each count value as shown below.
• 'CH1 Sampling pulse number' (Un\G0) is reset to 0. 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.
• 'CH1 Accumulating count value' (Un\G2, Un\G3) is reset to 0. If 'CH1 Preset setting value for accumulating count value'
(Un\G384, Un\G385) is set to a value other than 0, the accumulating count value is preset to the setting value.
• 'CH1 Input pulse value' (Un\G4, Un\G5) is reset to 0.
If a value other than Reset request (1) is set, the setting details are ignored.
