used to check rotation, alignment, or slowly move a load into
position. This is not time-limited but should be used cautiously.
5.6.4 Kick Start Mode
Kick Start applies a pulse of voltage to the motor producing a
momentary “kick” of high torque to break the motor load free from high
friction or frozen components. This pulse is limited to 2 seconds.
F022 = Kick Start Voltage
Factory Setting = 0 (Disabled)
Range = 10 - 100%
When F022 = anything but 0, a voltage “pulse” is applied before
the initial torque setting of F011 (or F012 if Current Ramp). This
sets the voltage level and the duration of the pulse is set by
F023. This setting should be higher than F011 (except for Dwell
Starting, see below) and high enough to provide a benefit in the
worst starting condition.
F023 = Kick Time
Factory Setting = 0.8 seconds
Range = 0.1 - 2 seconds
Sets the duration of time the Kick Start voltage is applied.
5.6.4.a “Dwell” operation using Kick Start
In some applications such as chain drive machinery, the Kick Start
feature can be used to slowly take up slack in the drive chain before
applying full torque. This is referred to as “Dwell Starting” because
the torque output stays low for a short time. To take advantage of
this feature, simply set the Kick Start to the same level as the Initial
Torque setting. This will only work in Voltage Ramp mode.
NOTE:
Do not use the Kick Start feature unless you determine that you
need it. Using this feature may eliminate many of the mechanical
and electrical benefits of using a Soft Starter.
