1. Check connections before applying AC line voltage to the drive.
2. Check that no conductive material is present on the printed circuit
board.
3. Verify that all selector switches are set correctly (see the following
section for selector switch settings). See Figure 10 for all switch
locations.

Operation
Before applying power
ATTENTION: Change voltage switch settings only when the drive is
disconnected from AC line voltage. Make sure both switches are set to
their correct position. If the switches are improperly set to a lower
voltage position, the motor will not run at full voltage and may cause
damage to the transformer. If the switches are improperly set to a
higher voltage position, the motor will overspeed, which may cause
motor damage or severe bodily injury or loss of life.

ATTENTION: Change slide switch settings only when the drive is
disconnected from the AC line voltage. Make sure both line voltage
and motor switches are set to their correct position. If the switches are
improperly set to a lower voltage position, the motor will not run at full
voltage and may cause transformer damage. If the switches are
improperly set to a higher voltage position, the motor will overspeed,
which may cause motor damage or severe bodily injury or loss of life.

1. Set the line voltage selector switches (SW501 and SW502) to 115 if
using 115 VAC line voltage, or to 230 if using 230 VAC line voltage.
2. Set the armature voltage selector switch (SW503) to 90 if using a 90
VDC motor, or to 180 if using a 180 VDC motor.
3. Set the feedback selector switch (SW504) to TACH if using a
tachogenerator; otherwise set it to ARM for armature feedback.
IMPORTANT: You may be required to derate a 90 VDC motor when
230 VAC is applied to the drive. Contact the factory for details.
