10) SOFT BRAKING
on
Every braking current is handled at normal values as
showed on the adjustments chart.
off
Every braking current is reduced by 25% when the soft
way is selected it is necessary that the jumpers in the
card are configured 1-3 and 2-4, and that the maximum
current level (IMax) is programmed to a value not inferior
to Six.
11) AUX FUNCTION
none
No Aux function.
bimotor contactor
AUX G7 output is activated when turning from
off status to running status and at the beginning of regen-
erative braking, and it is switched off when PWM is
greater than 20%, both statuses.
hydrocontactor The output AUX G7 commands the hydrodrive
contactor. It should be active during both forward and
backward directions and during release braking. The
turning OFF delay is programmable at "AUXILIARY
TIME".
12) HYDRO KEY ON (H2G software only)
on
Hydrodrive activation at key-on. Activation time is defined
by parameter AUXILIARY TIME.
off
Hydrodrive disable at key-on.
5.1.3 Parameter modification (PROGRAM MENU)
The parameters can be modified with the chopper in standby or running.
In the latter case, you must return to standby before switching off the chopper so that the
modifications are stored in the nonvolatile memory.
Regenerative traction parameters.
1) ACCELER DELAY = acceleration time, i.e. the minimum time during which the motor
voltage varies from 0V to the maximum.
2) INVERS BRAKING = basic braking current in direction inversion. A value is added to
this value based on the accelerator plus a fixed increment every second.
3) BRAKING (H2G software only) = braking current during plugging.
4) RELEASE BRAKING = release braking current (should have the lowest value).
5) PEDAL BRAKING = release braking current with brake pedal pressed.
6) CUTBACK SPEED 1 = reduction of speed no.1 (relative to input E3). A braking is
also associated (curve braking); the accelerator is reduced.
7) CUTBACK SPEED 2 = reduction of speed no.2 associated to input E2.
If the pin E2 input option is configured in the backing way , this parameter defines the
backing speed whose adjustment values are defined at the point "BACKING SPEED"
of the adjustment chart.
