[Minimum Freq]

This parameter sets the lowest frequency the drive
will output.

[Maximum Freq]

This parameter sets the highest frequency the drive
will output.

This parameter cannot be changed while the drive is
running.

[Stop Select 1]

This parameter selects the stopping mode when the
drive receives a valid stop command unless
[Stop Select 2] is selected.

Factory Default

“Coast”

Units

Display Drive
“Coast” 0

Causes the drive to turn off immediately.

“DC Brake” 1

Injects DC braking voltage into the motor.
Requires a value in both [DC Hold Time]
& [DC Hold Level].

“Ramp” 2

Drive decelerates to 0 Hz., then if [DC
Hold Time] & [DC Hold Level] are greater
than zero the holding brake is applied. If
the values equal zero, then the drive
turns off. Requires a value in [Decel Time
1] or [Decel Time 2].

“S Curve” 3

Drive causes S Curve Ramp to 0 Hz in
[Decel Time 1] or [Decel Time 2] x 2.

“Ramp to Hold” 4

Drive decelerates to zero Hertz then
injects holding brake per [DC Hold Level]
(limited to 70% of drive rated amps) until
a) a Start command is issued or b) the
Enable input is opened.

[Current Limit]

This parameter sets the maximum drive output
current that is allowed before current limiting occurs.
