4.5.2 Set Program Disable/Enable (OIM PROGRAM) - J16 Jumper
The OIM program jumper (J16) determines whether or not parameter changes can be made
through the keypad. Only programming options are affected by the setting of this jumper.
The OIM drive control keys (such as RUN) and the manual speed reference 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.

4.5.3 Set Field Loss Enable/Disable (FIELD LOSS DETECT) - J20 Jumper
The FIELD LOSS DETECT jumper (J20) determines whether or not a fault is generated when a
field loss occurs.
NOTE: Jumper J20 is ignored if the Field Current Regulator kit is installed. Therefore, placing
J20 in the DISABLE position will not disable field loss detection. See I/M 49’1345 for more
information on the Field Current Regulator.
WARNING
The user must provide external field current loss detection and inhibit drive operation via one of the
drive interlocks when this jumper is positioned to disable. Misapplication of this jumper can cause the
motor to run at dangerously high speeds.
Failure to observe this precaution could result in bodily injury.
To detect complete loss of field current, place the jumper on pins 1 and 2 (ENABLE). When a
complete loss is sensed, a fault is generated and the drive is stopped.
To ignore field loss, place the jumper on pins 2 and 3 (DISABLE). Any loss of field current is
than ignored. Use the DISABLE option only when no field exists, such as with a permanent
magnet or when a separate field supply is used.
4.5.4 Set Tacho Loss / Open Armature Enable/Disable
(TACHO LOSS DETECT) - J26 Jumper
This jumper determines whether or not a fault is generated when a tacho loss occurs or the
armature is open.
WARNING
When this jumper is removed and pins 1 and 3 connected, the user must provide external tacho loss
detection and inhibit drive operation via one of the drive interlocks. Misapplication of this jumper can
cause the motor to run at dangerously high speeds.
Failure to observe this precaution could result in bodily injury.
To detect tacho loss, place the jumper on pins 1 and 2 (ENABLE). When a loss is sensed,
a fault is generated and the drive is stopped. To ignore tacho loss or open armature, the jumper
must be removed and pins 1 and 3 connected (through wire-wrap connection).
