8) CUTBACK SPEED 3 = reduction of speed no.3 associated to input E1.
9) AUXILIARY TIME = Auxiliary contactor activating time connected to the G7 output
(request option or hardware modifications are necessary, see p.18)
10) COMPENSATION = compensation of the speed (motor voltage) on the basis of the
current when the speed reductions are active.
11) BRAKING MODUL = defines the maximum current in inversion braking with the
acelerator pedal pressed. When the accelerator is pressed all the way down in inver-
sion, braking becomes more brusque the higher the value of the parameter.
12) MAXIMUM CURRENT = defines the maximum current of the chopper both when
running and in braking. All the current adjustments are expressed as a percentage of
this value.
The adjustment interval is from 50% (level 0) to 100% (level 9).
13) MAX SPEED FORW = Max speed wit forward direction on. This speed reduction
goes under adjustable compensation with the COMPENSATION parameter.
14) MAX SPEED BACK = Max speed wit backward direction on. This speed reduction
goes under adjustable compensation with the COMPENSATION parameter.
15) CREEP SPEED = defines the minimum voltage applied to the motor with the running
request activated. Provides a more immediate response in starting off.
16) WEAK DROPOUT = threshold of current for opening the weakening contactor (if
programmed as such and not as bypass, in which case the output threshold is fixed
and not programmable).
17) CURVE BRAKING = current for curve braking, activated with RV1 request, if the
PWM is greater than 80% and the motor current less than 40%Imax.
17) CURVE TIME = curve braking time associated to RV1. If 0, braking is not carried out.
18) BACKING TIME = backing request activating time delay. If programmed at level 9
there is no time delay and the on status is present if a request is present.
