Unit Description / Notes
0.0 to 999
Setting the value to 0.0 s results in no Acceleration ramp.
[ 20 ]
Defines the time to accelerate (P100) linearly from zero up to the
maximum speed (P134) or to decelerate (P101) linearly from the
maximum speed down to 0 rpm.
0.0 to 999
The selection of the acceleration / deceleration time ramp 2 (P102 or
[ 20 ]
P103) can be made by reprogramming one of the digital inputs DI3 to
DI8. Refer to P265 to P270 in ramp 2.

-
The ramp S reduces the mechanical stress during the acceleration and
deceleration of the load.
0 or 1
Defines if the Frequency Reference Backup function is disabled (0) or
[ 1 ]
enabled (1).
-
If P120 = Off, the inverter does not save the current reference value,
when the inverter is enabled again, it will restart from the minimum
frequency setting (P133).
This back-up function is applicable to the keypad (HMI), E.P., Serial,
Fieldbus and PID Setpoint (P525) references.
