Parameter Purpose
A Steering Scalar value of 100% will double the %
turning so that 100% turning will occur at point ‘b’,
mid way between neutral and point ‘a’. Further
deflection towards point ‘a’ will not give any
increase in turning.
A higher value is more suitable for diamond shape
joystick restrictor plates, a lower value for square,
round or octagonal restrictor plates.
The purpose of this adjustment is to allow full lock
to be achieved with some wheelchair speed,
therefore higher values are more suitable for slower
wheelchairs and lower values for high speed
wheelchairs.
7.3.2 Other PCD Parameters
Parameter Purpose
Enable Lighting If set to ‘en’, lighting functions are enabled.
State en / dis If set to ‘dis’, there will be no response to a DX
Accessed by : OEM Remote lighting button being pressed (other than a
beep for some varieties of remotes).
Current Limit The current limit for the servo motor. The SLM will
ensure that no more than the stated current will go
Range 4 - 40 amperes through the servo motor.
Accessed by : OEM
PM Dir Scalar For use with two drive motor DX Systems and
compensates for different drive wheel spacing.
Range 0 - 100 %
Accessed by : OEM Determine how much one motor increases and the
other decreases in speed when the wheelchair is
turning. If this parameter is set to 100 %, the inner
drive wheel will have zero speed when turning.
This value has no effect when a DX-PM-S is used.
