Configure the VFD

All configurations required by the VFD are supplied by the HMI
through the VFD Gateway. The 19XRV, 23XRV Std Tier VFD
can operate with PIC III and PIC 6. Any configuration changes
necessary and possible are made on the HMI screens. A complete
set of configurations is transmitted to the VFD each time the con-
trols are powered up.
Table 2 lists parameters displayed on the 19XRV, 23XRV PIC3/
VFD_CONF screen. Table 3 shows parameters in the Unit
Mounted VFD Configuration menu for PIC6. Parameters in ital-
ics are to be entered or confirmed at start-up. Parameters in bold
are to be changed only after consulting with Carrier service engi-
neering.
