Type Reset
This feature assists the user when performing fault analysis or by
allowing a quick system setup change when required. Performing a
Type Reset results in one of the following user-selected post-reset
configurations.
Settings:
Auto Setup for 50 Hz
Auto Setup for 60 Hz
Restore Factory Defaults
Clear Trip
Clear Run Timer
New Base Drive Board

Direct Access Number — F007
Parameter Type — Selection List
Factory Default — None
Changeable During Run — No
Direction (of motor rotation)
No path available (Direct Access Only)
While operating using the LED Keypad Option this parameter sets the
direction of motor rotation. This setting may be changed during operation. This
setting will not override parameter F311 (Forward/Reverse Disable).
If either direction is disabled via parameter F311, the disabled direction will not
be recognized if commanded by the LED Keypad. If both directions are
disabled via parameter F311, the direction command from the LED Keypad
will determine the direction of the motor rotation.
Note: If using the LCD EOI, press ESC from the Frequency Command screen
to access this parameter.
Direct Access Number — F008

Factory Default — Forward

Fundamental Parameters

Accel/Decel #1 Settings
This parameter specifies the time in seconds for the drive to go from 0.0 Hz to
the Maximum Frequency for the #1 Acceleration profile. The accel/decel
pattern may be set using F502. The minimum accel/decel time may be set using
F508.
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.
