Acceleration time 4
F7.13
Deceleration time 4
PI9000 provides 4 groups of deceleration time, respectively F0.13\F0.14 and the above
3 groups of deceleration time.
The 4 groups of deceleration time are defined exactly the same, please refer to the
instructions of F0.13 and F0.14. The 4 groups of deceleration time can be switched through
different combinations of the multi-function digital input terminal DI, please refer to the
instructions of function code F1.00 to F1.07 in the attachment 2 for the detailed application
methods .

and acceleration time 2
Switching frequency point
F7.15
between deceleration time 1
and deceleration time 2
The function is active when motor 1 is selected and DI terminal is not selected to switch
between ac/deceleration. It is used to automatically select ac/deceleration time by not DI
terminal but the operating frequency range when the inverter is running.

Schematic diagram of switching between acceleration and deceleration
For the above figure in the process of acceleration, if the operating frequency is less
than F7.14, select acceleration time 1; otherwise select acceleration time 2.
For the above figure in the process of deceleration, if the operating frequency is more
than F7.15, select deceleration time 1; otherwise select deceleration time 2.

It is the waiting time that the inverter reaches zero speed when the parameter is used to
switch between forward and reverse rotation.
