Parameter Descriptions

4-41

Sets the time that the drive will remain in power loss mode before a fault is issued.

Sets the level at which the Power Loss Mode selection will occur.

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 OIM 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: 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.
