[Function] It starts the synchronizing operation of the shaft specified in Operand 1 as the slave
shaft following the master shaft. The electronic shaft operation settings such as the
master shaft are to be specified in the four variables in a row from Variable No. n in
Operand 2. The output section turns ON with the synchronizing start.

Operand 2 : Single Electronic Shaft Operation Settings
Variable
number
Data Description
n
Master shaft type 0 : Main CPU control shaft
1 : Pulse I/O board control shaft
2 : Pulse input channel
n+1
Master shaft number * Axes 1 to 6 (XSEL-P/Q), 1 to 8 axis (XSEL-R/S)
when main CPU control shaft, axes 0 to 15
when pulse I/O board control shaft, channels 0
to 3 when pulse input channel
n+2 Gear ratio numerator -10000 to -1, 1 to 10000
n+3 Gear ratio denominator 1 to 10000
The synchronizing process continues until:
y
XSYE Command (to cancel synchronizing process) is executed,
y
an operation cancel is executed to the slave shaft
(XSTP Command, CANC Command),
y
Synchronizing Process Repeat Type is set to 1 cycle and the master shaft
reaches to the stroke end, or the slave shaft operation program that XSFS
Command is executed is over.
If the gear ratio is set to a negative value, the slave shaft operates in a reverse
direction against the master shaft.
Caution
If there is a mistake in the single electronic cam operation settings specified in the variables in
Operand 2, Error No. 456 “Extension motion control board single electronic cam operation settings
error” would occur. The variable numbers with an error setting will be shown on the error list in
Info. 2 (in hexadecimal numbers).
y
Variable with an error occurred : Master shaft number
y
The specified master shaft number is inappropriate or invalid
y
The specified master shaft is a synchronized slave shaft or ZR unit shaft (if the master
shaft is a XSEL control shaft)
y
The specified master shaft is the shaft specified as the slave (if the master shaft is a
pulse I/O board control shaft)
y
The specified master shaft is on a different pulse I/O board or channel from that the
slave shaft is on (if the master shaft is a pulse I/O board control shaft or a pulse input
channel)
