Drive Control Parameters
78 S1A53838 09/2011
F721 [Loc. mot stop mode]
Local Mode Motor Stop Type
-0
0
1
The setting of parameter F721
determines the type of motor stop that will be executed when then embedded display terminal
STOP key is pressed.
The RUN and STOP keys needs to be enabled be setting parameter [Run/stop key] (F733) (see page 80
) to 0 for the motor to
stop when the embedded display terminal STOP key is pressed.
[Ramp stop]: Ramp stop
[Freewheel]: Freewheel stop
F295 [Switch rem/Local]
Bumpless transfer from remote to local control
-1
0
1
If parameter F295 is enabled, the speed reference, run and direction commands will be transferred from remote to local mode
when the LOC/REM key is pressed. Operation of the drive is not affected by a remote to local control mode transition.
If parameter F295 is disabled, a remote to local control mode transition will cause the drive to remove power from the motor. A
new run command and speed reference will need to be entered in the local mode.
Regardless of the setting of parameter F295, a local to remote transition will cause the drive to immediately respond to the remote
commands present at the moment of the transition.
[No bumpless]: Bumpless disabled
[Bumpless]: Bumpless enabled
F256 [Time limit low spd]
0.0 to 600 s 0.0 s
0
1
[Disable]: (0.0)
[Enable]: (0.01 to 600 seconds)
If parameter F256 is enabled and if the drive operates continuously at [Low limit frequency] (LL) (see page 82
) for a time period
equal to the setting of F256, the drive will ramp the motor to a stop. While the motor is stopped, “LStP” will flash on the drive
embedded display terminal.
When the speed reference to the drive exceeds the low speed level LL+F391, the drive will accelerate the motor to the new speed
reference.
If parameter F256 is enabled, drive operation at or below the low speed level is also monitored during startup or during reversing
of the motor. See diagram below.

Parameter [Remote spd ref 2] (F207) defines the remote mode secondary speed reference source. The setting of parameter [Au-
to/man speed ref] (F200) (see page 108
) determines whether this source is used for the speed reference.
If F200 is set to 0, a logic input terminal set to function 38 (see page 108
) determines if [Remote spd ref 2] (F207) identifies the
speed reference source.
If F200 is set to 1, [Remote spd ref 2] (F207) is the speed reference source when the drive’s output frequency is 1 Hz or below.
See diagram on page 46
for more detail.
