PARA. 52: Head output No. for ABS control
Set the head output No. of the destination for the absolute position data control.
Absolute position detection operation
1) When the power of the positioning unit is
turned ON, it drives the servo ON output and
the ABS transfer mode output.
2) In response to these outputs, 38(32+6)-bit data
is communicated while receiving and sending
are confirmed using the send data ready signal
and the ABS request signal.
3) The data is transmitted via the 2-bit line (ABS
bit 0 and ABS bit 1).
4) When detecting the absolute position, set
PARA. 16 (machine zero point address) to "0".
PARA. 53: Single-step operation
Set whether or not to perform the single-step operation.
PARA. 54 must be set when PARA. 53 is set to "1 (valid)".
PARA. 54: Single-step mode input No.
The single-step mode is valid while the input set here is ON.
Single-step operation
The single-step mode is valid while PARA. 53 is set to "1" and the input No. set to PARA. 54 is
ON. When the START signal is turned ON in the single-step mode, the specified program is
executed one line at a time.
The single-step mode can be made available by turning ON the M9000 (for the X axis), M9001
(for the Y axis) or M9002 (for subtask) instead of using PARA. 53 and PARA. 54. If special aux-
iliary relays are used the setting of PARA. 53 and PARA. 54 is not necessary.
