Parameter Descriptions

12-53

Selects the method for control of drive direction.

0 = Unipolar: The drive receives an unsigned reference signal and
a separate direction command from a logic source such as a digital
input or DPI port device.

Example: Analog speed reference = 0 to 100%

Direction control:

• OIM Forward/Reverse key

• Terminal block

1 = Bipolar: The drive receives a signed reference (-100% to
+100%). In this case, the Forward/Reverse key has no effect.

2 = Reverse Dis: The drive receives a signed reference (-100% to
+100%); however, regardless of the reference, the drive is not
permitted to reverse.

Note: Internal reference scaling provides 100% = 32767 internal
units.

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.
