(3) Speed changeover condition
If the movement amount is small in regard to the target speed, the
current speed may not reach the target speed even if
acceleration/deceleration is carried out. In this case, the machine
is accelerated/decelerated so that it nears the target speed.
If the movement amount will be exceeded when automatic
deceleration is required (Ex. Operation patterns "00", "01"), the
machine will immediately stop at the positioning address, and a
warning "insufficient movement amount" (warning code: 513) will
occur.
[When the speed cannot change over to the
P2 speed in P1]
When the relation of the speeds is P1 =
P4, P2 = P3, P1 < P2.
[When the movement amount is small during
automatic deceleration]
The movement amount required to carry out the
automatic deceleration cannot be secured, so the
machine immediately stops in a speed
