Overview of Version 1 Upgrades Section 1-12
• An overflow error will occur if the stroke width is not within a range of 0 to
7FFF FFFF hex after being converted to pulse units at the operating axis
pulse rate.
• An overflow error will occur if the cam rotation distance is not within a
range of 1 to 3FFF FFFF hex after being converted to pulse units at the
input axis pulse rate.
• The settable resolution in the cam table is 1/10,000 for input axis phases.
A maximum of 720 points can be set.
• An overflow error will occur if the input axis position is not within a range
of C000 0001 to 3FFF FFFF hex after being converted to pulse units at
the input axis pulse rate.
• An error (number out of range) will occur if a stroke width converted to
pulse units and multiplied by the stroke ratio is not within a range of C000
0001 to 3FFF FFFF hex.
• A traverse continuation error will occur if a cycle start is executed after
operation has been stopped by a driver alarm during electronic cam oper-
ation.
Operation Specifications
Start/End Condition Starting and stopping the electronic cam function depends on the conditions
that are set.
Start Condition
Not specified.
Electronic cam operation begins immediately after the electronic cam function
is executed (or after the preceding axis operation is completed when preread-
ing is executed).
Input Axis Position
Electronic cam operation is started when the position specified by the input
axis position is crossed. The input axis setting determines whether the com-
mand position or the present position (encoder) is used. The object of com-
parison is only the present position or command position display, and it is
unrelated to other input axis attributes (such as no origin and unlimited axes).
Latch
Electronic cam operation starts with the leading edge of the specified general-
purpose input or phase-Z input. When an encoder is used for the input axis,
hardware can be used to obtain an accurate starting position.
End Condition
One Rotation Only
Operation ends after one rotation (i.e., when the 0
°
position is reached) in
either direction. The operating axis is stopped at the 0
°
position of the input
axis and overtraveling distance will not be output.
Repeated
Operation is repeated with no limit, until an electronic cam/gear cancel, forced
block end, or optional end is executed.
