VFD Programming Parameters

Units shipped with an optional variable frequency drive
(VFD) are preset and run tested at the factory. If a problem
with a VFD occurs, ensure that the programmed parameters
listed in Table 25 have been set before replacing the drive.
Note: Check to make sure that parameter 104 is set
to 60 Hz. To check parameter 104 press the
Extended Menu button, press the Left Arrow button
until menu Load & Motor is shown, press the up
arrow until parameter 104 is displayed. Parameter
104 can then be modified by pressing the Change
Data button and then the Up Arrow button. When
the desired selection has been made press the OK
button.
Should replacing the a VFD become necessary, the re-
placement is not configured with all of Trane's operating pa-
rameters. The VFD must be programmed before attempting
to operate the unit.
To verify and/or program a VFD, use the following steps:
1. Remove the mode input (RTRM J6-2 and J6-4) or turn
the NSB panel to OFF so that the fan will not attempt to
start during programming.

WARNING
Hazardous Voltage! w/Capacitors!
Disconnect all electric power, including remote discon-
nects before servicing. Follow proper lockout/tagout pro-
cedures to ensure the power cannot be inadvertently en-
ergized. For variable frequency drives or other energy
storing components provided by Trane or others, refer to
the appropriate manufacturer's literature for allowable
waiting periods for discharge of capacitors. Verify with an
appropriate voltmeter that all capacitors have dis-
charged. Failure to disconnect power and discharge ca-
pacitors before servicing could result in death or serious
injury.
Note: For additional information regarding the safe dis-
charge of capacitors, see PROD-SVB06A-EN
