Acceleration Time 1
Program  Fundamental 1
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 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 increases 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 1
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 1
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
Note: This setting may not be lower than the Upper-Limit setting (F012).
Upper-Limit Frequency
Program  Fundamental 1
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.
