Source selection (see

). -
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.
20.000 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.
