SPEEDMASTER™ OPERATION MANUAL
Operation
Warning
Change voltage switch settings only when the drive is
disconnected from AC line voltage.
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.
Before applying power
• Set voltage switch SW501 to either 115 or 230 to match the
AC line voltage (see Figure 4, page 9).
• Set voltage switch SW502 to either 90 or 180 to match the
maximum armature voltage (see Figure 4, page 9).
• 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%.
