3-4 WebPak 3000 DC Drive Hardware Reference
3.4.2 Setting Program Protection Jumper (OIM PROGRAM) - J16
The OIM program jumper (J16) determines whether or not parameter changes can be made
through the keypad (OIM). Only programming options are affected by the setting of this jumper.
The OIM drive control keys (such as RUN) and JOG are not affected.
To allow keypad parameter changes, place the jumper on pins 1 and 2 (ENABLE).
To prevent parameter changes through the keypad, place the jumper on pins 2 and 3
(DISABLE). Parameters cannot be modified through the keypad. If an attempt to modify a
parameter is made, the message "Hardware Password Protection is Enabled" is displayed on
the keypad.
3.4.3 Inspect the Field Loss Detection Jumper J20
The FIELD LOSS DETECT jumper (J20) is not used with WebPak 3000 drives.
The position of this jumper has no effect on the drive
.
3.4.4 Inspect the Field Supply Jumper J21
The FIELD SUPPLY jumper (J21) is not used with WebPak 3000 drives.
The position of this jumper has no effect on the drive
.
3.4.5 Set the Source of Manual Mode Reference (MANUAL REF) - J19 Jumper
ATTENTION: The drive will not run at the correct speed if this jumper is not set to
the correct position. Failure to observe this precaution could result in damage to, or
destruction of, the equipment.
The MANUAL REF jumper (J19) determines whether the internal +10 V isolated power supply
or an external +10 V source is used for the Diameter/Taper Range or Trim Reference.
To use the +10 V power supply for the manual reference potentiometer, place the jumper on
pins 2 and 3 (POT). The supply at terminal 16 of the regulator board terminal strip is used.
To use an external +10 V source, place the jumper on pins 1 and 2 (EXT). The external
reference is connected at terminals 17 and 18 of the regulator board terminal strip.
NOTE: This input can be used as a trim on the Line Speed reference by setting the jumper on
pins 1 and 2 (EXT).
3.4.6 Set the Voltage Range and Scale of an Analog Tachometer (Jumpers J11 and J14)
The TACH V RANGE (J14) and TACH V SCALE (J11) jumpers set the voltage range and scale
of the analog tachometer.
NOTE: These jumpers are ignored if an analog tachometer is not used and if FEEDBACK
SELECT (P.200) is not set to DC TACH.
ATTENTION: The drive will not run at the correct speed if these jumpers are not
set to the correct position. Failure to observe this precaution could result in damage
to, or destruction of the equipment.
During Quick Start procedure, the drive calculates the value of the tachometer voltage range
based on the values of GEAR IN SPEED and ANLG TACH VOLTS/1000 and the setting of
FEEDBACK SELECT. The correct values are displayed on the Correct Scaling Jumper
Positions screen. Verify these settings before performing the Self Tuning procedure.
