TD Series Digital Solid State Soft Starter 48 - 1250A
5.5.4 Kick Start 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.
F022 = Kick Start
Factory Setting = 0 (Disabled)
Range = 0 - 1
Kick start applies a “pulse” of voltage to the motor to produce a
momentary “kick” of high torque to break the motor load free from high
friction or frozen components. When F022 = 1, this voltage “pulse”
begins the initial voltage applied in either F011 or F015. Voltage level is
adjusted by F023 and the time duration of the pulse is adjusted by
F024.
F023 = Kick Voltage
Factory Setting = 65%
Range = 10 - 100%
Sets the voltage level of the Kick Start feature. The setting of F023
should be higher than F011 and F015 and high enough to provide a
benefit in the worst starting condition.
F024 = Kick Time
Factory Setting = 0.8 seconds
Range = 0.1 - 2 seconds
Sets the duration of time the Kick Start voltage is applied.
5.5.5 Decel Mode
Deceleration is a feature of the TD Soft Starter which slowly decreases the
applied voltage to the motor when a stop command is given resulting in a gentle
decrease in motor torque. Deceleration provides a way to extend the stopping
time so that abrupt stopping does not occur. Deceleration is useful with centrifugal
pumps, material handlers, and conveyors where abrupt stopping could be
damaging to the equipment and/or load
Note: Decel is THE OPPOSITE of braking. Enabling the Decel feature will make the
motor take LONGER to stop than if it were simply turned off.
See Appendix 2 at the end of this manual for detailed descriptions of typical
applications for the Decel feature.
F025 = Deceleration Ramp
Factory Setting = 0 (Disabled)
Range = 0 - 2
When F025 = 0, the deceleration feature is disabled.
When F025 = 1, the deceleration feature is enabled AND the overload
protection feature, set with F003 and F004, is enabled. Even when the
stop command is received, the starter continues to apply decel voltage.
However, if an overload trip occurs, the starter stops applying voltage
and the motor coasts to a stop to prevent additional motor heating and
potential motor damage.
When F025 = 2, the deceleration feature is enabled and deceleration
will continue even when an overload condition trips.
Setting F025 = 2 presents significant risk of over-heating the motor beyond
its design limits which could result in motor damage and fire hazard. Do
this only in circumstances where the potential for mechanical damage
outweighs the risk of motor damage.
