Bit name
Positioning Com- Turns OFF during electronic cam execution regardless of
pleted Flag inputs.
Deceleration Stop Bit Uses up pulses accumulated in the error counter and stops.
The relationships of the electronic cam function to external I/O are described
in the following table.
Signal name
General-purpose Can be used as start condition.
inputs
Phase-Z input Can be used as start condition.
Limit inputs Causes a clockwise overtravel or counterclockwise overtravel
error. Operation is stopped immediately with no deceleration.
Emergency stop Causes an emergency stop input error. Operation is stopped
input immediately with no deceleration.
Driver alarm input Causes a driver alarm input error. Operation is stopped imme-
diately with no deceleration.
MPG input Can be used as electronic cam function G-code command
input.
Error counter reset When turned ON, operation is stopped for all tasks that
include that axis. When turned OFF, prereading is started
again.
The relationships of the electronic cam function to errors are described in the
following table.
Error classification
System errors When a system error occurs, the electronic cam function is
stopped for all tasks. Operation is stopped immediately with
no deceleration.
Task errors When a task error occurs, the electronic cam function is
stopped for that task. Operation is stopped immediately with
no deceleration.
Axis errors When an axis error occurs, the electronic cam function is
stopped in tasks performing operations for that axis. Operation
is stopped immediately with no deceleration.
The relationships of the electronic cam function to parameters are described
in the following table.
Parameter name
MPG/sync encoder When MPG is set for electronic cam function inputs, opera-
tions are executed according to this setting.
Minimum unit setting Not used for control by the electronic cam function.
Pulse rate numera- Used when data for the input axis and the operating axis that
tor/denominator is specified in mm units is to be converted to pulse units.
Software limits Detects software limit errors during operation if there are limits
set for the axis and if the origin has been determined.
Maximum feed rate An MPG ratio overflow error occurs if the command speed for
the operating axis exceeds the maximum feed rate.
Backlash compensa- Backlash compensation is enabled. It is executed according to
tion the direction of operation for the electronic cam function.
In-position Executes positioning completion checks according to the
operating mode when the electronic cam/gear function cancel
and optional end commands are executed.
Executes positioning completion checks for forced block end,
pause, servo error, and servo-unlock operations regardless of
the operating mode.
