This function is used
to change Accel/Decel
time at a certain frequency. This is useful in textile
industry applications. For example, when stop
command is activated when VFD is running at
100Hz, inverter decelerates with standard Decel
time to FG1-72 frequency and changes the Decel
time to I/O-51 setting.

The Acceleration and
Deceleration time
frequency range can be set to Maximum Frequency
or Delta Frequency.
Max. Frequency
- the VFD will increase its output
frequency from 0Hz to Max. Frequency or decrease
it from Max. Frequency to 0Hz within Accel or
Decel time. If Accel time is set to 60sec. and Max.
Frequency to 60Hz, the VFD will increase speed
from 10Hz to 30Hz in 20sec.
Delta Frequency
- the VFD will increase its output
frequency from current speed to a new Frequency
command or decrease it from current speed to new
Frequency command within Accel or Decel time. If
Accel time is set to 60sec. and Max. Frequency to
60Hz, it will take same time 60sec. to increase
speed from 10Hz to 30Hz or from 0Hz to Max.

FG1-74 has three
selections for
Accel/Decel time decimal point: 0.01sec., 0.1sec.,
1sec.
0.01sec
- This selection provides more precise
Accel/Decel time adjustment but limits it to
60.00sec.
0.1sec
- This the most common selection, provides
one decimal point for Accel/Decel time adjustment,
and limits it to 600.0sec.
1sec
- This selection provides no decimal points for
Accel/Decel time adjustment and limits it to
6000sec.

If FG1-81 parameter is
set to any number from
1 to 6000sec and start command is received,, the
VFD will start when Run Delay time expires . The
Run Delay can be used as a Backspin timer in pump
applications to prevent from starting the motor
rotated in reverse direction by back feed of water
flow.

When FG1-90 is set to Yes, the FG1-91 Up/Down
Saved Frequency Display and Save feature are
enabled. If SET-10 is set to Up/Down Keypad
speed control and speed reference was adjusted at
35Hz, the VFD will save this frequency when
power is turned off and when power is turned on
again, FG1-91 will show 35Hz that is the saved
VFD speed reference at start.
