This parameter realizes the acceleration ramp up to the
set value of the JOG voltage during the time at which
the digital Input (DI4) is closed. After opening, DI4 reali-
zes the deceleration via ramp, provided this function
has been enabled at P04.
NOTE!
1) The maximum activation time of the JOG function is
determined by the time set at P02. After this time
elapsed, the error E02 will be activated and the motor
disabled.
2) Thus P55 = 4.

function
6.3.15 - P34 - DC
braking time (s)
This parameter sets the DC braking time, provided P52=3
and P28=OFF. This function is only possible with the aid
of a contactor that must be connected according to Item
9.6 - Typic DC braking connection diagram.
This function must be used when reduction of the
deceleration time imposed by the load to the system is
desired.
NOTE!
1) Wherever these functions are used, you must consider a
possible thermal overload in the motor windings.
The thermal overload protection does not operate during
DC-braking.
2) There is no DC-braking when Soft-Starter is connected
within the motor delta connection.
