Default
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.
%
2.0
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.
Defines a time period for which,
following an enable signal being
applied to the drive, the drive will
run at the speed programmed
S
0.0
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.
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
S
0.0
Speed 8 (P2-08). This feature
can be used in applications such
as underground PCP pumps to
provide unwind of the driveshaft on
stopping.
