HI setting is only used when the stopping time is critical and must be around 1-2 seconds.
For this application 300% DC current is not adequate. Consult factory before using this
jumper position.
When the DC Injection unit is set on the HI level a current surge could occur due to the
motor CEMF and the free wheeling action of the power circuit.
