GBK60027 DX-SLM Installation Manual Issue 5
7.2.2
Drive Program Parameters
The DX System supports up to five Drive Programs. The Drive Programs are defined in
the DX Remote programming as factory settings specified by the customer. The Drive
Programs govern the driving performance of the wheelchair as suitable for different
environmental conditions.
The DX Remote Drive Programs are covered in the relevant DX Remote Installation
Manual. Three Drive Program Parameters are however treated differently in the servo
steered DX System.
7.2.2.1
Turning Speed @ Maximum
Parameter
Possible Values Default
HHP Lite Std Adv
Turning Speed @ Maximum (%) 10 - 100 %
-
The maximum speed available when the joystick is fully deflected left or right.
The value assigned to Maximum Turning Speed is not a single performance setting,
but a pointer to select one of eight Steering Programs: see section 7.3.1. The Steering
Programs are defined by the Wizard in the SLM wheelchair program.
The Maximum Turning Speed value selects a Steering Program as follows:
10 - 49 % selects Steering Program 1
50 - 54 % selects Steering Program 2
55 - 59 % selects Steering Program 3
60 - 64 % selects Steering Program 4
65 - 69 % selects Steering Program 5
70 - 74 % selects Steering Program 6
75 - 79 % selects Steering Program 7
80 - 100 % selects Steering Program 8
The Steering Programs values can be conventionally assigned so that Steering
Program 1 causes the slowest possible turning, progressing up to Steering Program 8
causes the fastest possible turning. If this recommendation is followed, Maximum
Turning Speed appears to have the same affect in a servo steering application as in a
conventional system
7.2.2.2
Turning Acceleration
Parameter
Possible Values Default
HHP Lite Std Adv
Turning Acceleration (%)
10 - 70 %
40 %
The rate of response when the joystick is deflected left or right from neutral. A value of
10% gives slow response, 70% gives fast response.
This defines the rate at which the SLM attempts to respond to a large increase in
steering lock. A small increase in lock demand is approached at the maximum
possible acceleration. The lock demand at which this parameter is used is set by the
Wizard in the SLM wheelchair program by the Turning Acceleration Point parameter.
