instruction.
The PCU begins to output the pulses at the execution of high-speed PTP start. However, the change
of the axis status is reflected in the axis status memory area at the next I/O refresh.
To execute multiple high-speed PTP start, design a self-holding circuit that executes an IOWR
If high-speed PTP start is executed continuously, 0.5 ms is required to process the IOWR

This is a high-speed PTP command.
Absolute movement: 80xx hex
Relative movement: 81xx hex
(xx = 01 to 04 hex: Axes 1 to 4)
Specify the first word in [Direct Operation Command
Memory Area] for the axis for which you want to execute
high-speed PTP start.
Axis 1: B
Axis 2: B+12
Axis 3: B+24
Axis 4: B+36
For the beginning word in [Direct Operation Command
Memory Area], refer to"Direct Operation Command
Memory Area" on page 5-64.
W: Set the destination unit number.
Specify a unit number between 0 and 94 in the decimal
&0 to 94 or in the hex #0000 to 005E.
W+1: Set the number of transfer words.
Set the number of words in [Direct Operation Command
Memory Area]. This value is fixed to #000C.
The Absolute movement received bit
and the relative movement received bit
in the axis status memory area will not
turn on at the execution of high-speed PTP start.
