Function configuration
The following table specifies parameters that select input variables of the
Speed/Torque Regulator function.
Parameter Description
Torque mode sel Selects the Boolean variable used to enable Torque ref input
in Speed and Torque modes, and to control entry & exit of
Ovrd/Spd forced mode within Torque, spd override modes.
Torque ref select
Selects the signal used as the Torque ref input signal. Note
that this parameter may specify normal signal sources
(acquired at the application loop rate) or one analog high-
bandwidth signal source (acquired at the motor control loop
rate).
Torque feed fwd
sel
Selects the signal used as a torque feedforward signal,
summed to the Torque ref pre limit in all states.
Spd reg init val
sel
Selects the signal used to define preconditioning of internal
state variables while in the Off/Precond state. The value of
the signal determines the target value of Speed reg output to
appear when the Speed/Torque Regulator function is enabled.
Variable inertia
sel
Selects the signal used to dynamically define the Inertia
compensation variable instead of being defined by the
constant Fixed inertia parameter.
The following table specifies the configuration parameters of the Speed/Torque
Regulator function.
Parameter Description
Regulator type Primary selector which configures the basic regulation mode
of the drive (see below).
Torque reg stop
mode
Boolean which enables the option to the Torque with Spillover
Speed mode in which speed regulation mode is dynamically
forced (Ovrd/Spd forced) during a stop sequence.
Spd reg prop
cmd gn
Proportional gain affecting only the command path of the
speed regulator compensation network.
Spd reg prop fbk
gn
Proportional gain affecting only the feedback path of the
speed regulator compensation network.
Spd reg prop
filter
Bandwidth of the first-order lowpass filter applied to the net
proportional path of the Speed regulator.
Spd reg integral
gn
Integral gain of the speed regulator compensation network.
Spd reg net gain
Common gain (inner loop gain) of the speed regulator
compensation network.
Fixed inertia Fixed inertia compensation term of the speed regulator
compensation network. Kilogram-meters² or Pound-feet²
Spd reg pos err
lim
Limit which defines the positive speed error tolerance for
activation of spillover speed mode (transition from Ovrd/Trq
act to Ovrd/Spd Low).
Spd reg neg err
lim
Limit which defines the negative speed error tolerance for
activation of spillover speed mode (transition from Ovrd/Trq
act to Ovrd/Spd High).
