Rockwell Automation FlexPak 3000 DC Drive Version 4.3 - Manual (Page 57)

Drive Setup and Adjustment 3-9
3.4.7 Set the Analog Auto Mode Reference (Jumpers J12 and J10)
The AUTOREF jumpers (J12 and J10) select the type of analog auto reference to be
used when the AUTO mode is selected. J12 selects the type of signal (voltage or
milliamps). J10 selects the range. See figure 3.4 for the jumper settings.

3.4.8 Scale the Armature Current Feedback (Jumper 18)
The ARM I FB RB jumper (J18) scales the armature current feedback signal. The
drive calculates the value of the burden resistor needed to scale the armature current
feedback signal. The calculations are based on the values of MOTOR RATED ARM
AMPS, MAXIMUM CURRENT and CT Turns Ratio.
The OIM displays the correct position of the jumper during the quick start procedure.
Verify this jumper setting before performing the self-tuning procedure.
3.4.9 Inspect Jumper J26
J26 is intended for use by Reliance factory personnel only. Verify that it is set as listed
in table 3.1.
3.4.10 Inspect the Spare 1 Jumper (J27)
J27 is not used. The position of this jumper has no effect on the drive. Verify that it is
set as listed in table 3.1.
3.4.11 Inspect the Filter Select Jumper (J28)
J28 is not used. Do not install a jumper block on this jumper.
3.4.12 Inspect the Spare 2 Jumper (J29)
J29 is not used. The position of this jumper has no effect on the drive. Verify that it is
set as listed in table 3.1.
!
ATTENTION: The drive will not operate at the correct speed if this jumper
is not set to the correct position. Failure to observe this precaution could
result in damage to, or destruction of, the equipment.
!
ATTENTION: Jumper J26 is for Reliance use only. The user must not
change the status of this jumper. Misapplication of this jumper can cause
the motor to run at dangerously high speeds. Failure to observe this
precaution could result in severe bodily injury or loss of life.
