Signal
Power failure deceleration signal PWFL <G159#3>
[Classification] Input signal
[Function] Posts the detection of a power failure.
[Operation] When this signal is set to 1, the control unit operates an follows:
Immediately performs deceleration stop according to an acceleration
value set in parameter No. 1670.

G159 PWFL
Parameter
1670 Acceleration for each axis for deceleration stop at power failure
[Input type] Parameter input
[Data type] Real number axis
[Unit of data] mm/sec/sec, inch/sec/sec, degrees/sec/sec (machine unit)
[Minimum unit of data] The increment system of the axis in question is followed.
[Valid data range] See the standard parameter setting table (D).
(For millimeter machines, 0.0 to +100000.0. For inch machines, 0.0 to
+10000.0)
Set an acceleration value by which deceleration stop is to be performed for the
target axis at power failure.
If this parameter is set to 0 for an axis, deceleration is not performed for that axis
upon a power failure.
In synchronization control and tandem control, set the same parameter value for
both the master and slave axes.
