60Hz and 50 Hz Motor Operation and Drive Output Frequency Selection (Jumpers J1
and J2) –
Both jumpers must be set for the appropriate motor nameplate frequency rating.
Jumpers J1 and J2 are located on the lower PC board.
6.2.1 Setting the Drive for 60 Hz or 50 Hz Motor Operation –
The drive is factory set to
operate 60 Hz motors. Jumper J1 is factory set to the “60Hz” position and Jumper J2
is factory set to the “X1” position. For 50 Hz motors, set Jumper J1 to the “50Hz” posi-
tion, and be sure Jumper J2 is set to the “X1” position. Jumpers J1 and J2 are located
on the lower PC board. See Figure 10.
6.2.2 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 horse-
power will result when operating the drive in the “X2” mode above the motor rated fre-
quency. See Figure 11, on page 26.
For 120 Hz output with 60 Hz motor, be sure Jumper J1 is set to the “60Hz” position
and set Jumper J2 to the “X2” position. For 100 Hz output with 50 Hz motor, set
Jumper J1 to the “50Hz”
position and set Jumper J2
to the “X2” position. See
Figure 12.
