The relationships of the electronic gear function to external I/O are described
in the following table.
Signal name
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 gear function G-code command
input.
The relationships of the electronic gear function to errors are described in the
following table.
Error classification
System errors When a system error occurs, the electronic gear function is
stopped for all tasks. Operation is stopped immediately with
no deceleration.
Task errors When a task error occurs, the electronic gear function is
stopped for that task. Operation is stopped immediately with
no deceleration.
Axis errors When an axis error occurs, the electronic gear function is
stopped in tasks performing operations for that axis. Operation
is stopped immediately with no deceleration.
The relationships of the electronic gear function to parameters are described
in the following table.
Parameter name
MPG/sync encoder When MPG is set for electronic gear function input, operations
are executed according to this setting.
Minimum unit setting Not used for control by the electronic gear function.
Pulse rate numerator Not used for control by the electronic gear function.
Pulse rate denomi- Not used for control by the electronic gear function.
nator
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 gear 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.
N000 P000 X
N001 G54 X0 .............................Presets X axis to 0.
N002 G63 E31=1000 .................Sets operand table from A1000.
N003 G63 A1000=1 ...................Electronic gear function
N004 G63 A1001=0 ...................Input axis = MPG
N005 G63 A1002=0 ...................Integrated axis = None
N006 G63 A1003=1 ...................Gear ratio numerator = 1
N007 G63 A1004=10 .................Gear ratio denominator = 10
N008 G01 X(E31).......................Operating axis = X axis
N009 G63 A1010=X ...................Gets present position of X axis.
