2.7.1 Jumper Locations and Settings
Jumpers J4 and J17 on the Regulator board are factoryset for voltage in and voltage out signals.
Refer to figures 2.8 and 2.9 for their locations on the Regulator boards. If you need to change the
jumpers' settings, use the following procedures.
CAUTION:
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.
2.7.1.1 Analog Input Speed Reference Jumper
Jumper J4 is the analog speed/torque (U.000) reference jumper. This jumper selects either
+/- 10 VDC or 020 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 instruction
manual D23339 for more information.
Use the following procedure to set jumper J4:
DANGER
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.
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 2.8 and 2.9.
Step 5. Locate pin 1 on jumper J4. Move the jumper to the desired setting as shown in figure 2.10.
Step 6. Reattach the cover.
Step 7. Reapply input power.
Step 8. Verify that Terminal Strip Analog Input Offset (P.009), Terminal Strip Analog Input Gain
(P.010), and Terminal Strip Analog Input Invert (P.011) are correctly set. Refer to instruction
manual D23339 for more information.
