Kick-start
Kick-start function provides sometime to motor to develop starting torque sufficient to
start spinning. The fast acceleration rate settings create risk for the motor to pull out
before it gets to follow the frequency reference. Instead, the function gives current
boost to motor at low speed for a set amount of time sufficient to develop starting
torque and eventually break through the static friction.
The function allows user to set desired speed and current reference for the motor
applied for a defined period of time. After the starting routine is completed, the drive
will automatically transit to accelerate to production speed with additional help of the
Acceleration assistance (if enabled).
