• Speed, V

(pps)
Note
When the designations for the next positioning operation are given during
operation, T
2
and T
3
are calculated using the acceleration time Ta and decel-
eration time Td specified at the time operation started from the stopped posi-
tion. It is not necessary to specify new acceleration and deceleration times.
Case 2: Speed for the Next Positioning Operation is Slower
In this case (V
1
>
V
2
), the calculations will be the same as before except for T
2
,
which is determined according to the following equation.
Actual acceleration time T
2
= (V
1
– V
2
)/(V
MAX
– V

7-6-3
Calculation of Acceleration/Deceleration Times when the Speed
is Changed During Operation
If the speed or the override setting is changed during direct operation, the
motor will be accelerated or decelerated to the new speed. The actual accel-
eration and deceleration times for this kind of operation can be calculated in
the way shown below.
Case 1: Next Speed is Faster
Actual acceleration time, T
1
= (V
1
– V
0
)/(V
MAX
– V

)

= (V
