ACCESSING PASSWORD PROTECTED PARAME-

TERS — Although the VFD controller has been preconfig-

ured as the factory, the user will need to be able to access the

parameters to verify the job specific parameters are correct,

tune the controller or correct a problem. The two passwords

protecting the VFD configuration are Parameter Set Display

(P.006) password and Program Disable (P.051) password. The

Parameter Set Display password restricts viewing. P.nnn pa-

rameters above 007 and all H.nnn and R.nnn screens. The pass-

word can be accessed at parameter P.006 and will switch be-

tween enabled and disabled each time the password 107 is en-

tered. The Program Disable password restricts the changing of

the drive parameter set. To enable or disable changes select pa-

rameter P.051 and enter the password 26.

NOTE: Some of the parameters can be changed only when the

drive is stopped.

See the Initial Start-Up Checklist section for VFD Job Spe-

cific Configuration table. For job specific parameters see inside

of the VFD enclosure door, next to the keypad. Refer to the

VFD Configuration table for the entire list of parameters.

NOTE: Restoring the default parameter P.050 will require all

the Carrier default parameters to be restored manually.

DRIVE PROTECTION AND OTHER INCOMING

WIRING

1. Verify that the branch disconnects or other local discon-

nects are open and properly tagged out.

2. Verify that the branch circuit protection and AC input

wiring to the VFD are in accordance with NEC/CEC

(National Electrical Code/California Energy Commis-

sion) and all other local codes.

3. Verify that the fuses are per the field wiring diagram.

4. Verify that the incoming source does not exceed 85 kA.

5. Verify the power lugs in the VFD and branch protection

are properly secured. Inspect the ground cable and ensure

it is properly connected at the branch and to the ground

lug in the VFD.
