This set of parameters defines the time to accelerate
linearly from zero up to the rated frequency and to
decelerate linearlyfrom the ratedfrequency down tozero.
The rated frequencyis defined by parameter:
- P145 in V/F control (P202 = 0 or 1).
- P403 in vector control (P202 = 2).
When factorysetting is used, inverter always follows the
time defined in P100 and P101.
If r
amp
2 is used
,
the acceleration and decelerationtimes
follow the values programmed at
P102
and
P103,
use a
digital input
.
Refer to the parameters
P263 to P265.
Depending on the load inertia, too short acceleration ti-
mes can disable the inverter due to overcurrent (E00).
Depending on the load inertia, too short deceleration ti-
mes can disable the inverter due to overvoltage (E01).
For more details, refer to the parameter P151.
