- 94 -
1790
Ratio of change time of the rate of change of acceleration in smooth
bell-shaped acceleration/deceleration before interpolation
[Input type] Parameter input
[Data type] Byte path
[Unit of data] %
[Valid data range] 0 to 50
Set the ratio of the change time of the rate of change of acceleration to
the change time of acceleration(*1) by percentage (%) in smooth
bell-shaped acceleration/deceleration before look-ahead interpolation.
If 0 is set in this parameter or a value not within the valid data range is
specified in this parameter, smooth bell-shaped acceleration/
deceleration before look-ahead interpolation is not performed.
(*1)
Parameter No. 1772 for acceleration/deceleration before look-ahead
interpolation (cutting feed).
Parameter No. 1672 for acceleration/deceleration before interpolation
in linear rapid traverse, or for optimum torque acceleration/
deceleration.
1791 Acceleration rate on each axis for the outage-time deceleration stop function
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm/sec/sec, inch/sec/sec, degree/sec/sec (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (D)
(0.0 to +100000.0 for the metric system, 0.0 to +10000.0 for the inch
system)
Set an acceleration rate for deceleration on an axis on which the tool is
decelerated to a stop at the time of power outage.
On an axis for which this parameter is set to 0, deceleration based on
the outage-time deceleration signal is not performed.
In synchronization control or tandem control, set the same parameter
for the master axis and slave axis.
