Figure 25 – Available Torque vs. Output Frequency
6.4 60 Hz and 50 Hz Motor Operation and
Drive Output Frequency Selection
(J4 and J5) – Both jumpers must be set
for the appropriate motor nameplate
frequency rating.
6.4.1 Setting the Drive for 60 Hz or
50 Hz Motor Operation – The
drive is factory set to operate
60 Hz motors. Jumper J4 is
factory set to the “1X” position
and Jumper J5 is factory set to
the “60Hz” position. For 50 Hz
motors, set Jumper J5 to the
“50Hz” position, and be sure
Jumper J4 is set to the “1X”
position. See Figure 24.
6.4.2 Setting the Drive for Two Times
the Rated Motor RPM – The
drive can also be used to operate
the motor up to two times the
rated RPM. However, constant
horsepower will result when
operating the drive in the “2X”
mode above the motor rated
frequency. See Figure 23.
For 120 Hz output with 60 Hz
motor, set Jumper J4 to the “2X”
position and be sure Jumper J5
is set to the “60Hz” position.
For 100 Hz output with 50 Hz
motor, set Jumper J4 to the “2X”
position and set Jumper J5 to
the “50Hz” position. See Figure
26 on page 25.
6.5 Boost Mode Selection (J6) – Jumper
J6 is factory set to the “FIX” position for
Fixed Boost. For Adjustable Boost using
the BOOST Trimpot, set Jumper J6 to the
“ADJ” position. See Figure 27 on page
25. Also see Section 13.8 on pages 31
and 32 for the BOOST Trimpot range.
