If the two motors of the powerchair do not perform exactly the same, the chair will
not drive in a straight line. The chair will slightly change its direction (veer) when it
drives forward.
Veer Compensation calculates how much the chair must correct its direction to go in
a straight line.

Notes:
1. Adjust this parameter every time a motor is replaced.
2. Other factors than motor performance can cause chair veer, for
example bent frames, flat tyres or faulty castor wheels. Correct
these problems at the source, do not use Veer Compensation.
3. Do not use Veer Compensation to compensate for out-of-centre
joystick deflection by the user.
