Forward/Reverse Run
Program Fundamental Standard Mode Selection
While operating in the Local mode, this parameter sets the direc-
tion of motor rotation.
From the Frequency Command screen, press the ESC key. At the
subsequent EOI Command screen, select the Direction field and
change the setting. Press the Rotary Encoder and the new set-
ting will be in effect.
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 keypad. If
both directions are disabled via parameter F311, the direction
command from the keypad will determine the direction of the
motor rotation.
Settings:
0 — Forward
1 — Reverse
2 — Forward (Switchable F/R by Keypad)
3 — Reverse (Switchable F/R by Keypad)
Direct Access Number —

Factory Default — Forward
Changeable During Run — Yes
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 Accel-
eration 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 fac-
tors: 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 volt-
age 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 fre-
quency and voltage automatically to produce smoother operation
or increased (starting) torque (see F502).
