Setting 3: Coast with Timer
When the Run command is removed, the drive will turn off its output and the motor will coast to stop. The drive will not start
if a Run command is input before the time t (C1-02) has expired. Cycle the Run command that was activated during time t
after t has expired to start the drive.
The wait time t is determined by the output frequency when the Run command is removed and by the active deceleration time.
n b1-04: Reverse Operation Selection
Enables and disables Reverse operation. For some applications, reverse motor rotation is not appropriate and may cause
problems (e.g., air handling units, pumps, etc.).
No.
b1-04
Setting 0: Reverse Enabled
Possible to operate the motor in both forward and reverse directions.
Setting 1: Reverse Disabled
Drive disregards a Reverse run command or a negative frequency reference.
n C1-01 to C1-04: Accel, Decel Times 1 and 2
Four different sets of acceleration and deceleration times can be set in the drive by digital inputs, motor selection, or switched
automatically.
Acceleration time parameters always set the time to accelerate from 0 Hz to the maximum output frequency (E1-04).
Deceleration time parameters always set the time to decelerate from maximum output frequency to 0 Hz. C1-01 and C1-02
are the default active accel/decel settings.
No.
