Variable Description
Torque ref post
lim
Torque reference after application of positive & negatvie torque
limits. Newton-meters or Pound-feet
Trq cur ref pre
lim
Torque-producing current reference, transformed from Torque
ref post lim by torque compensations, and enabled by Torque
enable req. RMS amps
Torque current
ref

& negative current limits. RMS amps
Motoring torque
lim
Net motoring torque limit, scaled according to 100% Motor
torque. Newton-meters or Pound-feet
Regen torque
limit
Net generating torque limit, scaled according to 100% Motor
torque, and reduced as necessary by DC Bus Regeneration
