NST Thresh-Hz FFt
Freewheel stop trip threshold:
when a stop on ramp or fast stop
is requested, the type of stop
selected is activated until the
speed falls below this threshold.
0 to HSP 0 Hz
Below this threshold, freewheel stop is activated. This
parameter can only be accessed if the R2 relay is not
assigned to the BLC: Brake Logic function, and if an on
ramp or fast type stop has been selected in the 3—Drive
menu under type of stop (Stt).
NOTE: Additional
parameters
appear in this
menu if certain
Macro-
Configurations are
selected. See
Tables 7–9.
Jump Freq. - Hz JPF
Jump frequency with a
bandwidth of +/- 2.5 Hz around
JPF.
0 to HSP 0 Hz
This function is used to suppress speeds which cause
mechanical resonance.
Jump Freq.2- Hz JF2
Second skip frequency: same
function as JPF, for a second
frequency value.

WARNING
NO HOLDING TORQUE
• DC injection braking does not provide holding torque at zero speed.
• DC injection braking does not function during loss of power or drive controller fault.
• When required, use a separate brake for holding torque.
EXCESSIVE DC INJECTION BRAKING
Application of DC injection braking for long periods of time can cause motor
overheating and damage. Protect the motor from extended periods of DC injection
braking.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
