Acceleration Time 1
Program Fundamental 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, 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 F502).
Deceleration Time 1
Program Fundamental Accel/Decel 1 Settings
This parameter specifies the time in seconds for the output of the ASD to go
from the Maximum Frequency to 0.0 Hz for the Deceleration 1 profile. The
Accel/Decel Pattern may be set using F502.
Note:
A deceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads. Automatic
Accel/Decel, Stall, and Ridethrough settings may lengthen the
deceleration times.
Maximum Frequency
Program 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.
The Maximum Frequency is not limited by this setting while operating in the
Drooping Control mode (see F320).
Note:
This setting may not be lower than the Upper-Limit Frequency
(F012) setting.
Upper-Limit Frequency
Program Fundamental 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).
Note:
This setting may not be higher than the Maximum Frequency
(F011) setting.
