 When the instruction is being executed may be modified DistanceOffset_Master,
DistanceAdd, DistanceSync
DistanceDec, the value of the retrigger Periodic_Master_Units Execute, the modified
parameters to take effect in the next cycle after the trigger cam Execute. After modifying
Mark_DI_Valid, Mark_DI_Num, Mark_DI_Edge value of the modified parameter re-trigger
Execute effective immediately. Execute and do not re-trigger CommandAborted set to
TRUE;
 Mode 2, if not performed on a complete cam cycle, the trigger signal and the color does not
immediately begin the next cycle again a cam;
 Under CANopen mode, colored punctuation function can not be used;
 MC_SpecialCamIn implemented instructions for controlling a synchronous movement of the
cam shaft from the cam in accordance with the relationship with the spindle preplanned;
 Source electronic cam shaft selectively to the real axis (AXIS0 ~ AXIS3) or the imaginary
axis or spindle (AXIS4);
 The electronic cam instruction parameters DistanceOffset_Master, AvtivationPosition,
DistanceAdd, DistanceSync, DistanceDec, electronic cam curve generated automatically;
cam position relationship between the main shaft as shown;

by a period from the spindle axis to recover the desired speed acceleration distance.
Example: Suppose claim spindleA motion to BAfter position (distancefor
100 Units),Electronic camFrom the shaftSynchronization with the main axis of the speed, the
acceleration distance of the electronic cam should be set to the number? Solution: Set
Electronic cam acceleration distance X,then X = 100 * 16/30;
