8.1.2. Execute
PHASER is a slave command, although it acts on the master signal. In the
command (like MOVE), the slave axis and offset value are essential. With
PHASER, there is a new factor ratio that translates between slave and
master units. The additional properties that can be determined are the
smoothness of change, profiler type,
STARTTYPE and kinematics.
A1.mastersource = a2.pcmd
A1.slave = CAM
Phase a1 10 ratio = 1 ‘ slave and master has the same units
8.1.3. Cancel
PHASER can be divided into two stages: the convergence and constant
stages. Stopping the convergence stage is by a special stop command. The
value reached at the end of stopping is the maximum offset that is added,
instead of the original offset value. The maximum offset value is queried with
MAXIMUMOFFSET (see the SERVOSTAR® MC. Reference manual).
To cancel the second stage, where the offset reaches its final value, insert a
new PHASER with a complementary correction value.
StopPhase a1 ratio = 1 ‘ slave and master has the same units
8.1.4. Serial PHASER
PHASER is inserted into the movements’ buffer. During the convergence
stage of PHASER, no other movements are allowed. A new movement or an
additional PHASER is held until the maximum offset is reached. Executing a
new motion during the convergence stage can be accomplished only with
STARTTYPE=IMMEDIATE. You can trace the convergence stage with
ISMOVING (like tracing other type of movements (see the SERVOSTAR®
MC. Reference manual).
