Hunt Prev
Gain
iii
[A421]
(Hunt Prevent Gain
iii
)
Determines the response to
changes in torque (torque slew rate
gain). Increasing the gain slows
drive torque response (more
dampening). Be cautious not to set
the parameter too high or the drive
will become unstable.
NOTE: it is usually best to leave this
parameter set at the default of 1.0
second.
Hunting can occur following a load
change, but it may also occur when
the motor is settling into a steady
speed. Hunting may cause the
motor to vibrate at lower speeds.
The Hunt Prevention function will
help to reduce or suppress this
oscillation.

Hunt Prev
Time
iii
[A422]
(Hunt Prevention Time Constant
iii
)
Hunt prevention filter time constant.
Adjusted for hunt prevention
response and stability. By
increasing the value of the
parameter, the response time of the
hunt prevention function will become
slower. Reducing the parameter to a
lower value makes the hunt
prevention function respond more
quickly. Note: the function works
better with a lower time constant.
NOTE: it is usually best to leave this
parameter set at the default of 0.2
seconds.
Hunting can occur following a load
change, but it may also occur when
the motor is settling into a steady
speed. Hunting may cause the
motor to vibrate at lower speeds.
