P6-10
Brake Chopper Duty
Cycle when Under
Temperature
0.0…20.0
%
2.0
This parameter defines the
duty cycle applied to the brake
chopper while the drive is in an
under temperature trip state. A
Brake resistor can be mounted
to the drive heat sink, and used
to warm the drive until the
correct operating temperature is
reached.
This parameter should be
used with extreme care, as
incorrect adjustment may result
in exceeding the rated power
capacity of the resistor. External
thermal protection for the
resistor should always be used
to avoid this risk.
P6-11
Preset Speed Run Time
On Enable
0.0..600.0
S
0.0
Defines a time period for which,
following an enable signal
being applied to the drive,
the drive will run at the speed
programmed in Preset Speed
7 (P2-07). This feature can be
used on pumps to provide a
reverse spin on start up, to
avoid potential blockages.
P6-12
Preset Speed Run Time
on Disable
0.0..600.0
S
0.0
Defines a time period for
which, following removal of
the enable (Run) signal and
the drive ramping to standstill,
the drive will then operate at
the speed set in Preset Speed
8 (P2-08). This feature can be
used in applications such as
underground PCP pumps to
provide unwind of the driveshaft
on stopping.
