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.
