Configuring DIP Switches
APEX6151 DIP Switches
The APEX6151 has three 8-position DIP switches. The switches are located behind a small
metal cover on top of the APEX6151. Loosen the two screws that hold the access cover, and
move the cover to expose the DIP switches.

The default setting for all DIP switches
when the APEX6151 ships from the
factory is off. You must set these
switches to configure the drive for your
particular application. Use a small
screwdriver to set the switches. The next
section summarizes the function of each
switch.
A diagram showing DIP switch
functions shown on page 7.
DIP Switch Location, with Cover Closed and Open
Switch 1 (SW 1)
REGEN FAULT — #1: Set this switch in the OFF position for normal operation of the
APEX6151’s internal regeneration circuit. For most applications, this switch should be OFF. If
you construct your own external regeneration circuit, set this switch ON to disable the
APEX6151’s regeneration fault. For more information, see the discussion of regeneration in
Chapter 5.
HALL SENSOR DEGREES — #2: Set this switch in the OFF position if you use a
motor with 120° Hall effect sensors. Set this switch in the ON position if you use a motor
with 60° Hall effect sensors.
RESERVED — #3: Set this switch in the OFF position.
MOTOR POLE PAIR NUMBER — #4 & #5: Set these two switches according to
the number of pole pairs your motor has. APEX and SM Series motors, which have two pole
pairs (four poles) require switches #4 & #5 to be OFF.
RESOLVER SPEED — #6: For a motor with a single speed resolver, turn #6 OFF.
(This switch should be OFF if you use an APEX or SM motor, all of which have single-speed
resolvers.) For a motor with a two-speed resolver, turn #6 ON.
