In this example, the empty hook current is considered in the range 10 … 12 A, both
in the forward and reverse direction. The current in the load condition is considered
in the range 20 … 25 A, both in the forward and reverse direction. In the empty hook
condition, the Load speed control function would allow the speed of 2000 rpm,
provided that the speed reference given is more than or equal to 2000 rpm, and the
speed is not limited by Par.
Minimum speed or
Maximum speed or any
other speed limits. In the load condition, if the actual motor current at the base speed
is within the range of 20 … 25 A, the Load speed control function will limit the speed
to 1300 rpm. Therefore, the functionality of two-speed control is achieved with these
settings.
The figure below shows the speed reference chain in Load speed control.
