Jumper Locations And Settings; Setting The Analog Input Speed Reference Jumper (J4) - Reliance electric GV3000 Instructions Manual

2.8.1 Jumper Locations and Settings

2.8.1.1 Setting the Analog Input Speed Reference Jumper (J4)

About the Drive
Jumpers J4 and J17 on the Regulator board are factory-set for voltage in and voltage
out signals. Refer to figures 2.9, 2.10, and 2.11 for their locations on the Regulator
boards. If you need to change the jumpers' settings, use the following procedures.
ATTENTION: Do not alter the setting of any jumper not described in this
instruction manual. Failure to observe this precaution could result in
!
damage to, or destruction of, the equipment.
Jumper J4 is the analog speed/torque (U.000) reference jumper. This jumper selects
either +/- 10 VDC or 0-20 mA input. Parameters P.009, P.010, and P.011 are used in
conjunction with the jumper.
Note that if the position of jumper J4 is changed after the parameters are
programmed, the software will not recognize that the input reference or polarity has
been changed. Be sure to verify that parameters P.009, P.010, and P.011 are correct
before starting the drive. Refer to the GV3000/SE Software Start-Up and Reference
manual for more information.
Use the following procedure to set jumper J4:
ATTENTION: DC bus capacitors retain hazardous voltages after input
power has been disconnected. After disconnecting input power, wait five
!
(5) minutes for the DC bus capacitors to discharge and then check the
voltage with a voltmeter to ensure the DC bus capacitors are discharged
before touching any internal components. Failure to observe this
precaution could result in severe bodily injury or loss of life.
Step 1. Turn off input power to the drive and wait five minutes.
Step 2. Remove the cover from the drive by unscrewing the four attaching screws.
On 200-400 HP drives, open the outer cabinet door.
ATTENTION: Do not operate 200-400 HP drives with the outer and inner
cabinet doors open due to possible exposure to high voltage. Close the
!
outer and inner cabinet doors before putting the drive into run. Failure to
observe this precaution could result in severe bodily injury or loss of life.
Step 3. Verify that the DC bus voltage is zero by following the procedure in section
9.3.
Step 4. Locate jumper J4 on the Regulator board. Refer to figures 2.9, 2.10, and
2.11.
Step 5. Locate pin 1 on jumper J4. Move the jumper to the desired setting as shown
in figure 2.12.
Step 6. Reattach the cover. On 200-400 HP drives, close the outer cabinet door.
Step 7. Reapply input power.
