-
☆
PI500-E 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 .
F7.14
Switching frequency point between
acceleration time 1 and acceleration time 2
0.00Hz~F0.19(maxim

0.00Hz
☆
F7.15
Switching frequency point between
deceleration time 1 and deceleration time 2
0.00Hz~F0.19(maxim
um frequency)
0.00Hz
☆
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.

If the operating frequency is less than F7.14, select acceleration time 2; otherwise select
acceleration time 1.
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.
F7.16 Forward/reverse rotation dead-band

0.0s
☆
It is the waiting time that the inverter reaches zero speed when the parameter is used to switch
between forward and reverse rotation.

For certain production equipment, the reverse rotation may result in damage to the
equipment, the function can disable the reverse rotation. The factory default allows reverse
rotation.
