target vehicles. The characteristics of one type of controller may not be compatible with a different,
unauthorized chair. Failure to observe this warning could result in an unsafe set-up for the
wheelchair user and may create a fire hazard depending on the motors, wiring, connectors and
circuit breakers installed on the unauthorized chair. PGDT accepts no liability for losses of any
kind arising from failure to comply with this condition.
7.3 Invert M1 Direction
This inverts the direction of rotation of motor channel M1. M1 relates to the left motor channel. The parameter can be set to on or
off.
On Means the motor output, M1, will be inverted.
Off Means the motor will rotate in the normal direction.
7.4 Invert M2 Direction
This inverts the direction of rotation of motor channel M2. M2 relates to the right motor channel. The parameter can be set to on
or off.
On Means the motor output, M2, will be inverted.
Off Means the motor will rotate in the normal direction.
7.5 Motor Swap
This swaps the motor output channels of the newVSI. I.e. left becomes right and right becomes left. The parameter can be set to
on or off.
On Means the motor outputs will be swapped.
Off Means the motor outputs will not be swapped.
7.6 Torque
The Torque parameter boosts the current to the motors at low speed settings. If the motor is stalled, for example, the wheelchair is
stuck against an obstacle, such as a door threshold; then this will be automatically detected and the current to the motors will be
increased, allowing the obstacle to be overcome.
Torque can be set between 0% and 100%
A value of 0% means the Torque parameter has no effect. Higher values mean that more current will be permitted in the
described stall conditions.
Ensure that the motor compensation is set correctly for the chair, torque does not counter the
effects of incorrect compensation settings.
The higher the Torque setting the more responsive the chair becomes to joystick commands. If set
too high, the chair can have a jerky or jumpy feel.
7.7 Tremor Damping
This parameter allows the effects of hand tremor to be reduced. If the user has a condition that results in hand tremor, then
increasing the value of Tremor Damping will reduce the effect of the tremor, making the wheelchair more controllable.
Tremor Damping can be set between 0% and 100%
A value of 0% means Tremor Damping has no effect. Note, even at this value, there is inherent damping in the controller. Higher
values apply a higher level of damping.
