INTERNAL SWITCHES

There are three sets of DIP switches, each consisting

of eight individual switches, located on the control

chip board. They are used to set the operational char-

acteristics of the drive for your specific application

and should not require resetting unless the applica-

tion or system requirements change. The switches

have two positions:

ONON

ON - toward the outside edge (top) of the circuit

board

OFFOFF

OFF - toward the center of the circuit board

NOTE: NOTE:

NOTE: A drive may have either rocker switches or

slide switches. For drives with slide switches, slide the

raised portion of the switch in the desired direction. For

drives with rocker switches, press in on the rocker

switch at the desired side.

position, the drive will attempt seven automatic

resets and will lock and hold the fault on the

eighth trip until it is manually cleared.

VARIABLE OVERLOAD

switch allows the overload trip curve to be tai-

lored to the application.

ONON

ON - Variable overload curve for cen-

trifugal and lightly loaded applications.

The OL trip curve is 100% current at full

speed and approximately 60% current at

zero speed.

OFFOFF

OFF - Constant torque loads may re-

quire more current, so the OL trip in

this mode is 100% current at all speeds.
