SETTING SELECTABLE JUMPERS
The drive has customer selectable jumpers
which must be set before the drive can be
used. For the location of jumpers, see
Figure 5, on page 14.
6.1 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 fre-
quency rating. Jumpers J1 and J2
are located on the lower PC board.
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”
position and be sure Jumper J2
is set to the “X1” position.
See Figure 20.
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
“X2” mode above the motor
rated frequency. See Figure 21.
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 22.
6.2 Automatic Start (CON1):
The drive is factory set for Automatic Start (jumper installed onto
CON1), as shown in Figure 23. CON1 is located on the lower PC board. The drive will auto-
matically start when power is applied and a Run Command* is given. The drive will auto-
matically restart after a recovered fault due to undervoltage, overvoltage, or short circuit.
For an I
2
t Trip, due to a prolonged overload, the drive must be manually restarted.
See Section 8.3, on page 27. Also see Section 9.2, on page 28.
*A Run Command can be any of the following: Main Speed Potentiometer Signal, Signal Following,
Manual Start Switch, Forward/Reverse Selection, or Enable. See Sections 5.4 – 5.8, on pages 16 – 20.
