13.2 TCF DRIVE PERSONALITY

Each TCF model has a unique "personality" (voltage and HP). This information is stored in

the EPM, and is also permanently stored within the drive. If the EPM is replaced, and the

personality stored in the EPM does not match the personality stored in the drive, it may trip

into a "bF" fault, depending on the information stored on the new EPM.

1. If the new EPM was from a TCF drive that was conﬁgured for V/Hz mode (refer to

Parameter 80 - DRIVE MODE), the drive will operate normally and will not trip into a "bF"

fault. To set up the drive for Vector mode, follow the instructions in Appendix A.

2. If the new EPM was from a TCF drive that was conﬁgured for Vector mode or

Enhanced V/Hz mode (refer to Parameter 80 - DRIVE MODE), the drive will trip into a

"bF" fault. This fault can be reset by one of two methods:

a. Perform a RESET 60 or RESET 50 using Parameter 48 - PROGRAM

SELECTION. This will reset all of the parameters back to factory defaults. To

set up the drive for Vector or Enhanced V/Hz mode, follow the instructions in

Appendix A.

b. Set parameters 85-91 properly for the connected motor and then set Parameter

94 - DRIVE PERSONALITY to the correct value based on the HP and voltage

rating of the drive. Then perform the Auto Calibration function according to the

instructions in Appendix A.

NOTE

If an attempt is made to change Parameter 94 - DRIVE PERSONALITY

before parameters 85-91 are changed, the drive will display a "GH" fault.
