Function outputs
The following table specifies the output variables of the Motor Control Interface
function.
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
Torque-producing current reference after application of posit ive
& 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 necessar y by DC Bus Regeneration
Control. Newton-meters or Pound-feet
Torque cmd pos
limit
Positive torque limit, derived from motoring & generating torque
limits according to direction-sensitive steering control. Newton-
meters or Pound-feet
Torque cmd neg
limit
Negative torque limit, derived from motoring & generating
torque limits according to direction-sensitive steering control.
Newton-meters or Pound-feet
Current limit Net current limit adjust. Per unit
Torque current
limit
Torque-producing current limit adjust, scaled accordi ng to
Motor rated current, and derived from the magnitude current
limit according to Flux current, avg. RMS amps
Ix command
pos limit
Positive current limit, derived from the torque-producing current
limit, and reduced as necessary by Pullout Limit & Power-Dip
Clamp Control. RMS amps
Ix command
neg limit
Negative current limit, derived from the torque-producing
current limit, and reduced as necessary by Pullout Limit &
Power-Dip Clamp Control. RMS amps
Flux ref ratio Net flux reference adjust signal.
