In application, the corresponding input terminal function should be set to "counter input" (function 20), and X4
port must be used when the pulse frequency is high.
When the count value reaches the set count value A0-03, the multi-function terminal Y outputs the "set count
value arrival" ON signal, and then the counter stops counting.
When the count value reaches the specified count value A0-04, the multi-function terminal Y outputs the
"specified count value arrival" ON signal, and the counter continues to count until the counter stops counting
when the "set count value" reached.
Counter reset operation (function 21) can be performed through multi-functional X terminal.

A0-05
Swing frequency setting mode
0: Relative to center frequency
1: Relative to the max frequency
This parameter is used to determine the reference value of swing.
0: relative to the center frequency (P0-03 frequency source), variable swing range system. The swing varies
with the center frequency (set frequency).
1: relative to the max output frequency (P0-13) is a constant swing range system with fixed swing range.

A0-06 swing amplitude AW:
When setting swing range relative to center frequency (A0-05 = 0), AW = frequency source P0-03 × amplitude
A0-06. When setting swing range relative to maximum output frequency (A0-05 = 1), AW = max output
frequency P0-13 × swing range PB-21.
A0-08 swing period: the time value of a complete swing period.
A0-07 jump frequency amplitude:
The jump frequency amplitude is the frequency percentage of the jump frequency relative to the swing range
when the swing frequency is running, that is: jump frequency = AW × jump frequency amplitude A0-07.
If the swing is relative to the center frequency (A0-05 = 0), the jump frequency is a changing value. If the swing
is relative to the max output frequency (A0-05 = 1), the jump frequency is a fixed value. The swing operating
frequency is constrained by the upper and lower limit frequencies.
A0-09 triangle wave rise time coefficient: it is the time percentage of triangle wave rise time relative to swing
period A0-08.
Triangle wave rise time (s) = swing period A0-08 × rise time coefficient of triangular wave A0-09;
Triangle wave falling time (s) = swing period A0-08 × (1 - triangular wave rise time coefficient A0-09).
