The
Speed Pot
function is adjusted by the
user
to decrease the maximum speed of
the chair according to his/her needs at the time. The adjustable value has a range of
0-100%. A Speed Pot value of 100% means that the maximum speed is equal to the
Speed @ Maximum
parameter. A Speed Pot value of 0% means that the maximum
speed is equal to the
Speed @ Minimum
parameter. Therefore Speed @ Minimum
actually means: The
Maximum Speed
when the
Speed Pot
function has the value
zero.
The Speed Pot function gets its input from a group of parameters:
•
A mechanical analogue speed pot (0-100%)
•
A digital speed pot on the Master Remote (0-100%)
•
The
Chair Speed
parameter (5.3.9.1) on the HHP (0-10, converted to 0-100%)
•
The DX BUS Speed Pot parameter (0-100%). Any DX Module can take control
of this parameter via the DX BUS.
The actual output value of the Speed Pot function will be the lowest of all the
parameters above.
The
Speed Limit
function allows
DX Modules
to limit the maximum speed when
necessary. For example: when the seat is raised, the speed of the chair must be
limited. The adjustable range (0-100%) is a percentage of the Speed @ Maximum
parameter.
The Speed Limit function gets its input from a group of parameters:
•
CLAM Slowdown (5.3.10.1)
•
The DX BUS Slow parameter. Any DX Module can take control of this
parameter via the DX BUS.
•
Maximum Demand Indicator (MDI). The Power Module indicates to the UCM
when it cannot fulfil the Speed Demand, for example when the user tries to go
up a slope that is too steep, or when the battery voltage would become
higher than the Maximum Motor Volts parameter (4.3.2.12).
•
Internal stability algorithms that momentarily limit the speed for safety reasons.
The actual output value of the Speed Limit function will be the lowest of all the
parameters above.
