definately not normal, the speed control should work both directions.
if it was a 2700 or 2800 i would say it was one of the 'close to the
end' slowdown limit switches, but the 1000sdx doesn't have that 
feature.  i would disconnect wires 4 and 5 and see if the drive
voltage is the same each direction, if it isn't i would suspect
the control box otherwise check out the rotor itself.  if it comes
down to the control box i would start with d13, q10 and c13 which
rectify and control the rotor voltage.
