194 Parameters
Selects a source that switches between the two sets of
acceleration/deceleration times defined by parameters
.
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.

-
Defines acceleration time 1 as the time required for the
frequency to change from zero to the frequency defined
by parameter
. After this
frequency has been reached, the acceleration continues
with the same rate to the value defined by parameter
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
Defines deceleration time 1 as the time required for the
frequency to change from the frequency defined by
parameter
(
not
from parameter
) to zero.
If there is any doubt about the deceleration time being too
short, ensure that DC 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
Defines acceleration time 2. See parameter
.
60.000 s
0.000…1800.000 s
Acceleration time 2.
10 = 1 s
Defines deceleration time 2. See parameter
.
60.000 s
0.000…1800.000 s
Deceleration time 2.
10 = 1 s
No.
