The following table specifies the continuous signal variables of the Speed/Torque
Regulator function.

Speed reg output

Core regulator output of the Speed/Torque Regulator
function, the scaled and gated sum of proportional
(variable Speed reg prop term) and integral (variable
Speed reg int term) regulator components. Newton-
meters or Pound-feet

Torque ref pre limit

Final output of the Speed/Torque Regulator function
provided to the motor control interface, the sum of the
primary output of the speed regulator (variable Speed
reg output), torque refererence (gated signal selected by
parameter Torque ref select) and torque feedforward
(non-gated signal selected by parameter Torque feed
fwd sel). Newton-meters or Pound-feet

Speed reg error

Primary regulator error signal equal to the difference

between Speed reg reference and Speed reg fbk. RPM

Spd reg integral ref

Conditioned error signal which defines the reference to
the regulator integrator structure; differs from Speed reg
error only in Torque, spd override mode (see below).
RPM

Speed reg int term

Regulator integral component.

Speed reg prop term

Regulator proportional component.

Inertia

Active inertia compensation signal in use by the
regulator, derived from either the Fixed inertia
parameter or from the variable specified by parameter
Variable inertia sel. Kilogram-meters

² or Pound-feet²

Speed reg net gain

Active net gain compensation in use by the regulator,
the scaled product of Inertia and the parameter Spd reg

net gain.

The following table specifies the logical signal variables of the Speed/Torque
Regulator function.

Speed reg mode

Primary state variable which reflects the active
regulation state of the drive.

Enable spd reg out

Boolean signal from the primary regulator control logic
which enables active signals to the variable Speed reg
output.

Torque mode sel

Boolean signal from the primary regulator control logic

which gates the variable Torque ref input.

Speed reg antiwindup

Boolean signal indicating that the speed regulator

integrator value is frozen as an anti-windup response.
