acceleration/deceleration times defined by parameters
28.72…28.75.
0 = Acceleration time 1 and deceleration time 1 are in force
1 = Acceleration time 2 and deceleration time 2 are in force

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 (not to 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.
20.000 s
0.000…1800.000 s Acceleration time 1. 10 = 1 s
28.73 Freq deceleration
time 1
Defines deceleration time 1 as the time required for the
frequency to change from the frequency defined by
parameter 46.02 Frequency scaling (not from parameter
30.14 Maximum frequency) to zero.
If there is any doubt about the deceleration time being too
short, ensure that DC overvoltage control (30.30
Overvoltage control) is on.
Note: If a short deceleration time is needed for a high
inertia application, the drive should be equipped with
braking equipment such as a brake chopper and brake
resistor.
20.000 s
0.000…1800.000 s Deceleration time 1. 10 = 1 s
28.74 Freq acceleration
time 2
Defines acceleration time 2. See parameter 28.72 Freq
acceleration time 1.
60.000 s
0.000…1800.000 s Acceleration time 2. 10 = 1 s
28.75 Freq deceleration
time 2
Defines deceleration time 2. See parameter 28.73 Freq
