When Deceleration at Step 1 is Possible:
When the Changed Speed Exceeds One-half the Starting Speed
If deceleration is not possible at step 1 and the time from duplicate starts to stopping exceeds
250 seconds, this fixes stopping time at 250 seconds.
In this case, because there is a fixed deceleration time of 250 seconds, the axis does not
decelerate immediately even when you implement multiple starts and the movement distance
is adjusted by setting the constant-speed section.
The formula below shows the changed speed which is more than half the difference between
the starting speed and command speed:
V2 >
Operation to satisfy the above formula is categorized into two.
Starting speed
specified with
parameters V0
First, the axis decelerates to command speed V2 over deceleration time T2. When the
movement distance is short and thus it exceeds the specified distance if the axis decelerates
over deceleration time T2, the deceleration time changes depending on the movement
distance. In other words, the axis decelerates over a time that is shorter than the specified
deceleration time.
