2.6.1 Jumper Locations and Settings
Jumpers J4 and J17 on the Regulator board are factory-set for voltage in and voltage
out signals. Refer to figure 2.5 for their locations on the Regulator board. If you need
to change the jumpers’ settings, use the following procedures.
2.6.1.1 Setting the Analog Input Speed Reference Jumper (J4)
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 LiquiFlo Software Start-Up and Reference
manual for more information.
Use the following procedure to set jumper J4:
Step 1. Turn off input power to the drive and wait five minutes.
Step 2. Open the door of the enclosure.
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 figure 2.5.
Step 5. Locate pin 1 on jumper J4. Move the jumper to the desired setting as shown
in figure 2.6.
Step 6. Close the door of the enclosure.
Step 7. Reapply input power.
!
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.
!
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.
