Ex.1) (+) + (+) =
By entering , you can activate the reverse run function and the acceleration/deceleration
time #2 function at the same time.
Ex.2) (+) + (+) + (+)=
By entering , you can activate the forward run function and the acceleration/deceleration
time #4 function at the same time.
(Selecting both of acc/dec switching #1 and acc/dec switching #2 means selection
of acceleration/deceleration time #4. This manner is common to V/f pattern and
torque limit.)
