D. Plug in module
Plug the VFD interface module's 6-pin connector into the "PL3"
socket on the VFD.
E. Set VFD parameters
For proper functionality, set the following VFD parameters in the order shown from the VFD's main keypad:
Parameter Set to
P199
00
P100
02
P400
01
P166
00
Note: The P166 setting should only be set to 00 on VFDs mounted to the fan motor frame. All other "long
lead" installations should remain set to 01.
Note: A control configuration fault ("F_Fnr") may be displayed after you change P100 or P400. You can
ignore this fault by pressing STOP on the main VFD keypad.
F. Install jumper wire
Do not install the jumper wire before making the parameter changes listed in the previous step.
Power down the fan, and then insert a jumper wire between terminals 1 and 4 on the VFD terminal strip for a
drive RUN enable.
