Special
Accel/Decel (1 – 4) Settings
This parameter specifies the time in seconds for the output of the ASD to go
from 0.0 Hz to the
Maximum Frequency
for the
1 Acceleration
profile. The
Accel/Decel pattern may be set using
. The minimum Accel/Decel time
may be set using
.
Note:
An acceleration time shorter than that which the load will allow
may cause nuisance tripping and mechanical stress to loads.
Automatic Accel/Decel
,
Stall
, and
Ridethrough
settings
may
lengthen the acceleration times.
Acceleration
The acceleration rate of a motor is determined by several factors: applied
power, applied load, and the physical properties of the motor (winding
parameters, motor size, etc.). The ASD will control the first of these factors:
input power. The settings of the ASD will control the frequency and amplitude
of the applied voltage to the motor.
Under most operating conditions, as the output frequency of the ASD goes up
so does the output voltage (linear acceleration). The ASD has the ability to
modify the relationship between frequency and voltage automatically to
produce smoother operation or increased (starting) torque (see
