SPEEDMASTER™ OPERATION MANUAL

Before applying power

• Set voltage switch SW501 to either 115 or 230 to match the

AC line voltage. Set voltage switch SW502 to either 90 or 180

to match the maximum armature voltage (see Figure 14).

• Verify that no conductive material is present on the printed

circuit board.

• If using a 90 VDC or 130 VDC motor with 230 VAC line

voltage, derate the nameplate motor speed and torque by at

least 30%.

Warning

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. If the switches are improperly set to a

higher voltage position, the motor will overspeed, which

may cause motor damage.
