Accel/Decel 1 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

Acceleration 1

profile. The

Accel/Decel pattern may be set using

F502

Note:

An acceleration time shorter than that which the load will allow
may cause nuisance tripping and mechanical stress to loads.

Automatic Accel/Decel

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

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.

The

Maximum Frequency

is not limited by this setting while operating in the

Drooping Control

mode (see

This setting may not be lower than the

Frequency Settings

This parameter sets the highest frequency that the ASD will accept as a
frequency command or frequency setpoint. The ASD may output frequencies
higher than the

Upper-Limit Frequency

(but, lower than the

Maximum

Frequency

) when operating in the

PID Control

mode,

Torque Control

mode,

or the

Vector Control

modes (sensorless or feedback).
