VR2 CONTROL SYSTEM

PG DRIVES TECHNOLOGY

The chair manufacturer is responsible for ensuring that the
control system is matched to the motor resistance. Failure
to do this may result in poor control characteristics, which
in extreme instances can make a chair uncontrollable and
potentially unsafe. PGDT accepts no liability for losses of
any kind arising from failure to comply with this condition.
The chair manufacturer is responsible for always ensuring
that any replacement motors or gearboxes are fully
compatible with the originals that the control system was
designed to match. Failure to do this may result in poor
control characteristics, which in extreme instances can make
a chair uncontrollable and potentially unsafe. PGDT accepts
no liability for losses of any kind arising from failure to
comply with this condition.
Users must not move a control system from one chair type
to install it on a different chair type. Control systems with
different part numbers may have both hardware and
software differences to ensure that they are compatible
with the electrical and dynamic characteristics of their
specific target vehicles. The characteristics of one type of
control system 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.
8.3 Invert M1 Direction
This inverts the direction of rotation of motor channel M1. On a standard VR2, 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.
8.4 Invert M2 Direction
This inverts the direction of rotation of motor channel M2. On a standard VR2, 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.
8.5 Motor Swap
This swaps the motor output channels of the VR2. I.e. left becomes right and right
becomes left. The parameter can be set to on or off.
