Rockwell Automation Liqui-Flo DBT Reach Drive - Manual (Page 77)

Parameter Descriptions 3-51
Sets the time that current is below the level set in Load Loss Level (188) before a fault
occurs.
Sets the time that the drive is at or above current limit before a fault occurs. Zero
disables this feature.
Selects the source for control of drive direction.
Unipolar = Drive receives unsigned reference (0 to 32767) and direction command
separately (from the DPI port). For example, the direction keys on an HIM apply the
direction to the reference.
Bipolar = Drive receives signed reference (-32767 to 32767). In this case, the
direction keys have no effect.
Reverse Disable = Drive receives signed reference (-32767 to 32767); however,
regardless of the reference, the drive is not permitted to reverse.

ATTENTION: When using bipolar analog inputs, unpredictable changes
in motor speed and direction can be caused by noise and drift in sensitive
circuits. Use speed command parameters to help reduce input source
sensitivity. Failure to observe this precaution could result in bodily injury
or damage to equipment.
ATTENTION: Setting parameter 190 to 0 or 1 may cause unwanted motor
direction. Verify driven machinery cannot be damaged by reverse rotation
before changing the setting of this parameter to 0 or 1. Failure to observe
this precaution could result in damage to, or destruction of, equipment.
