NOTES During continuous operation, the operation moves on to the next table after the position com-
mand speed becomes 0.
During continuous operation, no point table selection signal is received. Select the position feed
length by point tables before turning ON the start command. Only the maximum frequency can
be changed during operation. Position feed length cannot be switched.
Positioning operation by point tables, example 2 (variable speed operation)
● The maximum frequency can be changed during positioning operation. Use as many point tables
as the number of maximum speeds to be set.
● The figure below shows an operation example when the following settings are made for point
tables.
