2.6.1 Jumper Locations and Settings

2.6.1.1 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 figure 2.6 for their locations on the Regulator board. 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 Bookshelf Drive Software Start-Up
and Reference manual for more information about these parameters.
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. Disconnect, lock out, and tag all incoming power to the drive.
Step 2. Wait five minutes for the DC bus capacitors to discharge.
Step 3. Disconnect any wiring from the face of the drive.
Important: The cover is connected to the drive by the keypad/display cable. To
disconnect the cover, use the procedure below. Do not remove the
keypad/display.
Step 4. Remove the cover as follows:
a. Unscrew the attaching screw on the cover.
b. Lift the cover and carefully take it out of the heatsink as far as the flat
ribbon keypad cable will allow. This cable connects the display with the
Regulator board.
c. Use a screwdriver to slide the cable out of the connector on the Regulator
board to completely detach the cover.
Step 5. 24 to 43 A drives only: Remove the front panel by unscrewing the two
attaching screws.
Step 6. Verify that the DC bus voltage is zero before touching any internal
components by following the procedure in section 10.3.
