Programming 6–13
Advanced Setup
[Sync Time]
The time it takes for the drive to ramp from the “held
frequency reference” to the “current frequency reference”
after the Sync input is de-energized. Refer to
Synchronized Speed Change Function on page 6–12 .
Parameter Number 307
Parameter Type Read and Write
Factory Default 0.1 Second / Seconds x 10
Factory Default 0.0 Sec
Minimum Value 0.0 Sec
Maximum Value 6000.0 Sec
[Stop Select 1]
This parameter selects the stopping mode when the drive
receives a valid stop command unless [Stop Select 2] is
selected.
Parameter Number 10
Parameter Type Read and Write
Factory Default “Coast”
Units Display Drive
“Coast” 0
Causes the drive to turn off
immediately.
“DC Brake” 1 Drive defluxes the motor and then
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.
[DC Hold Time]
This value sets the amount of time that the
[DC Hold Level] voltage will be applied to the motor when
the stop mode is set to either “DC Brake” or “Ramp.” [DC
Hold Time] is ignored when the stop mode ([Stop Select
1], [Stop Select 2]) is set to “Ramp to Hold.”
Parameter Number 12
Parameter Type Read and Write
Display Units / Drive Units 1 Second / Seconds x 10
Factory Default 0.0 Sec
Minimum Value 0.0 Sec
Maximum Value 90.0 Sec
[DC Hold Level]
This value sets the DC voltage applied to the motor to
produce the selected current during braking, when the stop
mode is set to either “DC Brake,” “Ramp” or “Ramp to
Hold.” If “Ramp to Hold” is the active stop mode, [DC Hold
Level] will be clamped at 70%, even if higher values are
programmed.
Parameter Number 13
Parameter Type Read and Write
Display Units / Drive Units 1 % of [Rated Amps] / 4096 = 100%
Factory Default 0 %
Minimum Value 0 %
Maximum Value 150 %
ATTENTION: If a hazard of injury due to movement of equipment or material
exists, an auxiliary mechanical braking device must be used to stop the motor.
ATTENTION: This feature should not be used with synchronous or
permanent magnet motors. Motors may be demagnetized during braking.
