LEVEL
LO
(Normal) Braking action starts when motor starter has opened
and the motor terminal voltage has decreased to
30% of the line voltage.
HI Braking action starts when motor starter has opened
and the motor terminal voltage has decreased to
80% of the line voltage. See important notes below.
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 OP-STOP 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.
