PARAMETERS
Example 1 of positioning operation by point tables (automatic
continuous positioning operation)
The figure below shows an operation example when the following settings are made for point tables.
NOTE
• During continuous operation, the operation moves on to the next table after the position command 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.
Example 2 of positioning operation by point tables (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.
• Set "0" as the dwell time to perform variable speed operation.
