Acceleration Time 1
Program
Fundamental
ACC/DEC 1 Settings
This parameter specifies the time in seconds for the drive to go from 0.0
Hz to the Maximum Frequency for the Acceleration 1 profile. The accel/
decel pattern may be set using
. The minimum accel/decel time
may be set using
.
Note:
An acceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads.
Automatic Accel/Decel and Stall settings may lengthen the acceleration
time.
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 control the frequency
and amplitude of the applied voltage to the motor.
Under most operating conditions, as the output frequency of the drive
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.

ACC/DEC 1 Settings
This parameter specifies the time in seconds for the drive to go from the
Maximum Frequency to 0.0 Hz for the Deceleration 1 profile. The accel/

When operating with the Automatic Accel/Decel enabled (
minimum accel/decel time may be set using
Note:
A deceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads.
Automatic Accel/Decel and Stall settings may lengthen the acceleration

Fundamental
Frequency Settings
This setting determines the absolute maximum frequency that the ASD
can output.
Accel/decel times are calculated based on the Maximum Frequency
setting.
Note: This setting may not be lower than the Upper-Limit setting (
).
