* Allowable forward rate: the allowable maximum proportion of the forward path . Please see below
for details.
E-Cam current position
Max. forward rotation limit. Counterclockwise is
forward direction in the figure
Target position is within the range; onward trip
is in forward direction
Target position is within the range; return trip
is in reverse direction
Allowable forward
rate = 0% ( 0° ),
reverse direction
only for onward trip
Allowable forward
rate = 25% , onward
max. path +90°
Allowable forward rate = 50% ,
onward max. path +180°
Allowable forward
rate = 75% , onward
max. path +270°
Allowable forward
rate = 100%
( 360° ), forward
direction only for
onward trip
Failure code F0E1h When executing this macro command, E-Cam is not in engaged status.
E-Cam has to be engaged to execute the alignment correction.
Failure code F0E2h P5.093.YX (PR number) exceeds the range: 0 – 0x3F
Failure code F0E3h P5.093.UZ (maximum alignment correction rate) exceeds the range: 0 – 0x64 (%)
Failure code F0E4h P5.094 (DI delay time compensation) exceeds the range: -10000 to +10000
Failure code F0E5h P5.095 (allowable forward rate) exceeds the range: 0 – 100 (%)
Failure code F0E6h P5.096 (alignment target position) exceeds the range: 0 to (P5.084/P5.083) - 1
Command code
000Fh
Calculate the moving distance between current and target position of E-Cam
for PR positioning.
General parameters N/A
Macro parameters
P5.093.Low_Word = UZYX (4 digits, HEX)
YX (PR number of onward trip) = 0 – 0X3F (invalid when value is 0).
UX (PR number of return trip) = 0 – 0X3F (invalid when value is 0).
P5.093.Hi_Word = must be set to 0.
P5.095 (allowable forward rate) = 0 – 100 (%)
P5.096 (target position X) (unit: pulse number of master axis) = 0 to (P5.084 /
P5.083) - 1.
Monitoring variable 062(3Eh): displays the current engaged position (X) of master axis.
When E-Cam is engaged, this macro command calculates the moving distance between the
current
and target engaged position (X) and writes the value into the specified PR.
You can use this macro command: during E-Cam operation, if you want to move the slave axis to the
specified position when the master axis stops but is still in engaged status. This macro command can
calculate the correct
moving distance
(Y_Drift)
of the onward trip
for the PR incremental command.
