• Function
These parameters allow you to combine a maximum of 30 operation frequencies, operation time and
acceleration/deceleration time (15 combinations of parameters x 2 patterns) for automatic pattern operation
by means of the terminal board.

For details, refer to Section 5.12.
Note: When the function of auto-restart is active, the time spent for speed search is added to the operation time set
for pattern operation. Consequently, the effective operation time sometimes becomes shorter than the settled
operation time.
