Programming 7–13
Advanced Setup
[Sync Time]
The time it takes for the drive to ramp from the “held
frequencyreference”tothe“currentfrequencyreference”
after the Sync input is de-energized. Refer to
Synchronized Speed Change Function on page
7–12.
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]
Thisparameterselectsthe stoppingmode whenthe 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. Requiresa valuein both [DC
Hold Time] & [DC Hold Level].
“Ramp” 2 Drivedeceleratesto0Hz.,thenif[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 DrivecausesS CurveRampto 0Hz
in[DecelTime 1]or [DecelTime 2]x
2.
“Ramp to Hold” 4 Drivedeceleratesto zeroHertz 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 HoldLevel]voltage willbe appliedto themotor when
the stop mode isset to either “DC Brake” or “Ramp.” [DC
HoldTime]isignoredwhen[StopSelect1]or[StopSelect
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

If“RamptoHold” isthe activestopmode,[DCHold Level]
will be limited to the current listed in the Derating
Guidelines (Appendix A), even if higher values are
programmed.
