• 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 to approach the target speed.
If the movement amount will be exceeded when automatic deceleration is required (Ex. Operation patterns "00", "01", etc.),
the machine will immediately stop at the designated positioning address, and the warning "Insufficient movement amount"
(warning code: 0D58H) will occur.
[When the speed cannot change over in P2]
For the following relation of the speed P1 = P4, P2 = P3, P1 < P2
