operator from stopping and re-starting the motor which can result in the slow speed operation time of the
motor being exceeded.
Slow Speed Kick Level: The Slow Speed Kick Level sets the short-term current level that is applied to the motor to accelerate the
motor for slow speed operation. The Slow Speed Kick feature is disabled if it is set to off. Slow Speed Kick
can be used to "break loose" difficult to start loads while keeping the operating slow speed current level
lower.
This parameter should be set to a midrange value and then the Slow Speed Kick Time should be increased in
0.1 second intervals until the kick is applied long enough to start the motor rotating. If the motor does not
start rotating with the set Slow Speed Kick Level increase the level and begin adjusting the kick time from 1.0
seconds again.
If the motor initially accelerates too fast then reduce the Slow Speed Kick Level and/or reduce the Slow Speed
Kick Time.
Slow Speed Kick Time: The Slow Speed Kick Time parameter sets the length of time that the Slow Speed Kick current level is applied
to the motor at the beginning of slow speed operation. After the Slow Speed Kick Level is set, the Slow
Speed Kick Time should be adjusted so that the motor starts rotating when a slow speed command is given.
If the motor initially accelerates too fast then reduce the Slow Speed Kick Level and/or reduce the Slow Speed
Kick Time.
