Symmetrical lim, Positive lim and Negative lim
The speed regulator is saturated by the Speed reference selections. UsingTorque ref 1
and/or Torque ref 3 it is possible to regulate the output torque from the maximum to zero.
In case of slippage or material break, the speed will increase up to reach the speed
reference, or until the net torque ref is below needed load current.
It is possible to select Torque ref 1 + Torque ref 3 to act:
· [1] Symmetrical lim
On positive and negative limits symmetrically (Torque ref sum must be
positive; if it’s negative the value is clamped to zero)
· [2] Positive lim
Torque ref only modifies the Positive limit (Torque ref sum must be positive; if
it.s negative the value is clamped to zero)
· [3] Negative lim
Torque ref only modifies the negative limit (Torque ref sum must be negative; if
it.s positive the value is clamped to zero)
Positive SpeedTorque, Negative SpeedTorque
In this case the torque requested by the Speed regulator is compared with the sum of
Torque ref 1
+
Torque ref 3
. If the Net Torque ref is lower in respect to the Speed
regulator command, the Torque ref wins and it is given as reference to the Current
regulator (Iq Current).
Otherwise the Speed regulator command will produce the reference for the current
regulator. It is possible to select
Torque ref 1
+
Torque ref 3
to act:
· [4] Positive SpdTrq
Saturating the speed regulator output positive, the sum of Torque ref 1 +
Torque ref 3 can be positive or negative.
The sum of Torque ref 1 + Torque ref 3 will be Torque ref unless the Speed
regulator output is more negative than the sum of Torque ref 1 +Torque ref 3.
If sum of Torque ref 1 + Torque ref 3 is negative, while the Speed regulator
output is positive, an external control may be needed to keep from motor
overspeed in the negative direction, during a material break or slippage.
