P0.T0
These parameters are used to set the acceleration time and deceleration time for acceleration and
deceleration.
Acceleration time 0: The time that accelerates from 0 to maximum frequency (P0.TT).
Deceleration time 0: The time that decelerates from maximum frequency (P0.TT) to 0.
S curve time: The time for S curve is used to improve the smoothness characteristic of the start and stop
during acceleration and deceleration, P0.T0 S curve time is applicable to smooth acceleration and
deceleration to minimize abrupt shock to the load, such as the belt conveyor that carries fragile
materials.
When P0.T0= 0, it indicates without S curve time, the acceleration and deceleration is in linear mode.
When P0.T0 is set to a non−zero, it indicates that there is S curve time, and the acceleration and
deceleration adopts S curve mode.
Actual S curve acceleration time = Actual acceleration time+S curve time
Actual S curve deceleration time = Actual deceleration time+S curve time
As shown in the following figure, curve T is the curve representing the accelerationTdeceleration in linear
mode, curve T is the curve representing the accelerationTdeceleration in S curve mode.
Curves T and T corresponding to the same setting frequency. The actual accelerationTdeceleration time
of curve T is longer than that of curve T by the time set by P0.T0.
Note:
 The S curve time setting is also available for accelerationTdeceleration time T, T and 3 (P4.09~P4.T4).
 It is suggest setting the S curve time is TT5 of the accelerationTdeceleration time.
