194 Parameters
28.71 Freq ramp set
selection
Selects a source that switches between the two sets of
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.
Note: The default value depends on the selected macro.
See chapter Control macros on page 27.

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
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.
3.000 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
deceleration time 1.
60.000 s
0.000…1800.000 s Deceleration time 2. 10 = 1 s
