G74/G75/G76 Enabled for electronic cam function. G75 is disabled, however,
for continuous operation after an error occurs when an oper-
and is specified.
G90/G91 None. The electronic cam function is unrelated to the coordi-
nate system.

A second block can be preread and executed for the same
operating axis, and operation proceeds to the next block. If a
third electronic gear function or electronic cam function is exe-
cuted for the same operating axis, the operation waits for the
first electronic gear function or electronic cam function to be
completed.

function)
The relationships of the electronic cam function to control bits and flags are
described in the following table.
Bit name
Automatic/Manual If the mode is switched from automatic to manual during elec-
Mode tronic cam function execution, the electronic cam function is
paused. Operation is stopped immediately, with no decelera-
tion. Continuous execution is possible if the operating axis is
not moved during the pause.
Forced Block End Bit Enabled for the electronic cam function. Operation is stopped
immediately with no deceleration. For continuous operation,
the previous operations are all cleared and execution pro-
ceeds again from the present block.
Pause Bit Enabled for the electronic cam function. Operation is stopped
immediately with no deceleration. Continuous execution is
possible if the operating axis is not moved during the pause.
Servo-unlock Bit Enabled for the electronic cam function. Operation is stopped
immediately with no deceleration. Continuous execution is not
possible.
Axis Operating Flag Turns ON during electronic cam execution regardless of
inputs.
Relationship to electronic cam function
gear/cam function is used as the operating axis for
another electronic gear/cam function, execute the com-
mand where the axis is not the operating axis for the
electronic gear/cam function first. These commands will
be automatically executed in this order even if they are
placed in the reverse order.
Also, if the G code commands for electronic gears/cams
serve as the input and output for each other and the
order cannot be determined, an MPG ratio overflow
error will occur.
