4. HOW TO USE THE POINT TABLE
3) Position data unit ([Pr. PT01])
Set the unit of the position data.
4) Feed length multiplication ([Pr. PT03])
Set the feed length multiplication (STM) of the position data.
[Pr. PT03] setting
_ _ _ 0 - 999.999 to + 999.999
_ _ _ 1 - 9999.99 to + 9999.99
_ _ _ 2 - 99999.9 to + 99999.9
_ _ _ 3 - 999999 to + 999999
Note 1. The feed length multiplication setting ([Pr. PT03]) is not applied to the unit multiplication factor.
Adjust the unit multiplication factor in the electronic gear setting ([Pr. PA06] and [Pr. PA07]).
2. The "-" sign has different meanings under the absolute value command method and the incremental value command method.
Refer to section 4.2.1 for details.
(c) Operation
Selecting DI0 to DI7 for the point table and switching on ST1 starts positioning to the position data at
the set speed, acceleration time constant and deceleration time constant. At this time, ST2 (Reverse
rotation start) is invalid.
