2.12.5 Speed loop optimisation
CONFIGURATION ► FREQ. INVERTER ► SPEED LOOP
LOOP GAIN
Frequency loop gain (FLG)
Used to adapt the pace of the machine speed transients according to the dynamics.
For machines with high resistive torque, high inertia or fast cycles, increase the gain
gradually.
Vibrations may occur if there is too much gain. If there is no access to the gain, there
may be a difference between the chosen speed and the actual car speed.
[0 .. 100] %
LOOP STAB
Loop stability (StA)
Used to adapt the return to steady state after a speed transient, according to the
dynamics of the machine. Gradually increase the stability to increase control loop
attenuation and thus reduce any overspeed.
[0 .. 100] %
REJECTOR FILTER
Notch Filter Activation (nFA)
This parameter activates the notch filter function. 2 independent notch filters can be
configured.
This parameter can’t be modified without our after sale service support.
[NO] [FIRST] [SECOND] [ALL]
2.12.6 RollBack function for synchronous motors
CONFIGURATION ► FREQ. INVERTER ► ROLLBACK
ROLLBACK MGT
Activation of Rollback management function (rbM)
[NO] [YES]
ROLLBACK COMP.
Rollback compensation gain. (rbC)
[0..1000] % (by default 20 %)
ROLLBACK DAMPING
Rollback coefficient damping. (rbd)
[0..1000] % (by default 50 %)
RIGIDITY CTRL
Activation of start-up stiffness boost function. (SUSb)
This function is compliant with the rollback management function Rollback . It is
recommended to activate both.
The Start-up stiffness boost adapts the IBR current level according to the encoder
feedback while the brake is opening.
[NO] [YES]
