.
0 = Acceleration time 1 and deceleration time 1 are in
force.
1 = Acceleration time 2 and deceleration time 2 are in
force.
Note:
The default value depends on the selected macro.

FBA A
Only for the Transparent16 or Transparent32 profile.
Transparent16 or Transparent32 control word bit received
through the fieldbus A interface.

28.72
Freq acceleration time
1
Defines acceleration time 1 as the time required for the
frequency to change from zero to the frequency defined
by parameter
46.02
Frequency scaling
. After this
frequency has been reached, the acceleration continues
with the same rate to the value defined by parameter
30.14
Maximum frequency
.
If the reference increases faster than the set acceleration
rate, the motor will follow the acceleration rate.
If the reference increases slower than the set acceleration
rate, the motor frequency will follow the reference.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to
exceed the drive torque limits.
3.000 s
0.000…1800.000 s
Acceleration time 1.
10 = 1 s
