10:4 Tune torque control
Path in menu:
Menu/SETTINGS/Functional Settings/Torque control/
Tune T-Ctrl
With this parameter it is possible to change the speed of the
regulator that regulates the voltage so that the torque will
follow a predefined torque curve. In most cases, this
parameter will not have to be changed from its default value
which is 100%. If a dip occurs in the torque curve during stop,
increasing this parameter can solve the problem. This
parameter should not be set too high though, since this can
cause the torque of the motor to oscillate around the
predefined torque curve. If this is the case, decrease this
parameter.
10:5 Start ramp
Path in menu:
Menu/SETTINGS/Functional Settings/
Start/Stop / Start Ramp
When a start signal is given the softstarter performs a start
ramp by controlling the output voltage to the motor so that
either the voltage or the torque increases from the start level
to full voltage, depending on which ramp type is selected.
The start ramp continues until full voltage is applied to the
motor.
