SYNCC
Summary Synchronization in CAM-Mode
Syntax SYNCC num
Parameter num = number of curves to be processed;
0 = the drive remains in CAM-Mode until another mode is started with
commands such as MOTOR STOP, CSTART, POSA, etc.
Description The command SYNCC starts the CAM-Mode (CAM control). From this moment, the
curve positions of the master are counted depending on the actual master
positions and the defined starting behavior in par. 33-23
Start Behavior for Sync :
Where and when counting is started. With the parameter SYNCMSTART = 2000,
the curve positions of the master are only counted after the next master marker.
NB!:
SYNCC does not start the slave drive nor does it interrupt on-going motions (e.g.
CVEL), only SYNCCSTART does.
NB!:
The drive remains in CAM-Mode until num curves have been processed success-
fully.
If the synchronization (after num curves) is being closed normally, the start stop
point pair 2 will be used – if no SYNCCSTOP with a corresponding point pair is
defined – in order to stop the drive. It will then come to a stop at the position
slavepos (see parameters).
Command Group CAM
Cross Index SYNCCSTART
Syntax Example DIM curve [280] // see number of elements in the title bar of the CAM-Editor
SETCURVE curve // Set curve
SYNCC
// Synchronization in CAM-Mode
Fix points of a curve:
Master Slave
0
500
700
1000

300
1200
Sample
Hence in SYNCC 1 command thus locks the slave and master position as per the
array.
