7-6-2 Calculation of Acceleration/Deceleration Times for Continuous
Positioning
The actual acceleration and deceleration times when a command for a new posi-
tioning operation is made during direct operation can be calculated in the way
shown below.
Case 1: Speed for the Next Positioning Operation is Faster
Actual acceleration time, T
1
= (V

-- V

)/(V

Note
When the designations for the next positioning operation are given during
operation, T
