Chapter 7 Function Block
7-40
7.7.2 Speed Synchronization (XPM_SSS)
Form of Function Block Description
Input
REQ : Request for execution of function block
BASE : Set the base no. with module
SLOT : Set the slot no. with module
AXIS : Axis to command
XBF-PN04B:1~4, XBF-PN08B:1~8
MST_AXIS : Set main axis
XBF-PN04B:1~4, XBF-PN08B:1~8,
9: Encoder1,
MST_RAT : Set speed rate of main axis
-32,768 ~ 32,767
SLV_RAT : Set speed rate of sub axis
-32,768 ~ 32,767
Output
DONE : Maintain 1 after first operating
STAT : Output the error no. in operation
(1) Give “Speed Synchronization” command to the axis designated as the axis of positioning module with BASE
(Base no. of Positioning module) and SLOT (Slot no. of Positioning module).
(2) This command is for operating at the operation speed ratio between main axis and subordinate axis.
(3) There is no rule about size of the speed ratio between main/sub axis. If the speed ratio of main axis is bigger
than sub’s, the main axis will move faster than sub axis. If the speed ratio of sub axis is bigger than main’s, the
sub axis moves faster than main.
(4) You can set axis to command in “AXIS” and the following value is available. If you set other values, error code
“6” appears.
XBF-PN04B:1~4, XBF-PN08B:1~8
(5) You may set the main axis on MST_AXIS with following values. If you set wrongly, “Error6” arises.
XBF-PN04B:1~4, XBF-PN08B:1~8, 9 : Encoder1
(6) The operating direction of subordinate depends on speed synchronization ratio

. If it is positive,
operate in direction of main axis. If it is negative, operate in reverse direction of main axis.
