Rockwell Automation FlexPak 3000 DC Drive Version 4.3 - Manual (Page 52)

3-4 FlexPak 3000 DC Drive Hardware Reference Version 4.3
Verify that there is no path to ground in either the DC motor armature circuit, the shunt
field circuit or the thermostat circuit. Connect one lead of an ohmmeter to the motor
frame and the other lead to the two armature leads, then to the two field leads and to
the two thermostat leads. If a reading of less than 100,000 ohms is observed, a
ground condition exists and MUST be corrected before power is applied.
3.4 Set Jumpers
The jumper settings for the FlexPak 3000 drive determine the regulator type, program
protection, field settings, references for automatic and manual modes, tachometer
voltage range, and armature feedback scaling.
There are a few guidelines for setting jumpers:
• Through the OIM, check the current jumper settings for J11, J14, and J18 in the
Correct Scaling Jumper Positions menu under Drive Information. Write down
these settings as displayed and make sure the actual settings match.
• Through the OIM, check the current settings for J15, J20, and J21 in the Drive
Information menu. If these settings are correct for your system, you do not need to
change them.
Jumpers are read only on power-up, so power must be cycled for a change to a
jumper setting to be recognized by the drive.
To set the jumpers:
Step 1. Remove power from the drive.
Step 2. Remove the cover. Refer to figure 2.15 for cover removal. You do not need to
remove the keypad.
Step 3. The jumpers are located on the Regulator board. See figure 3.3 for jumper
locations.
Step 4. Set the jumpers as described in sections 3.4.1 through 3.4.13. Record the
settings in table 3.1.

ATTENTION: This equipment is at line voltage when AC power is
connected to the drive. Disconnect and lock out incoming power to the
drive before proceeding. After power is removed, verify with a voltmeter
at power terminals 181, 182, and 183 that no voltage exists before
touching any internal parts of the drive. Failure to observe this precaution
could result in severe bodily injury or loss of life.
ATTENTION: Unless explicitly stated otherwise, power must be removed
before changing any jumper connection. Failure to observe this
precaution could result in damage to, or destruction of, the equipment.
