Set the VFD Programming Parameters
Complete the following tasks to set and verify the TR170 parameters listed in the tables in
“TR170 VFD Program Parameters,” p. 15 section.
Power Up the VFD
1. When all components have been mounted and wired, close all electrical enclosures.
2. Restore machine power.
3. Place the unit in “STOP” to prevent unintended operation.
4. Open the cover or door over the drive and verify the drive has powered up.
NNoottee:: The drive cooling fan may be operating, even if the unit is in standby mode.

Reset Parameters Back to Factory Defaults
NNoottee:: In the event the drive parameters are inaccessible or the drive display fails, a "hard reset"
may be accomplished by holding "OK" and "Menu" buttons while cycling the drive power.
To reset all programming parameters back to the factory defaults:
1. Go to parameter 1144––2222 OOppeerraattiioonn MMooddee.
2. Press OOKK.
3. Select 22 ““IInniittiiaalliizzaattiioonn””.
4. Press OOKK.
5. Cut off the main supply and wait until the display turns off.
6. Reconnect the main supply.
The frequency converter is now reset.
7. Ensure parameter 14–22 Operation Mode has reverted back to “Normal Operation”.
NNootteess::
• Step 5 resets the drive to the default factory settings. The program parameters
listed in Table 7, p. 16, Table 8, p. 17 and Table 9, p. 18 will need to be verified or
changed as described in the previous Modify Parameters procedure.
• Some of the parameters listed in the Table are motor specific. Due to various
motors and efficiencies available, use only the values stamped on the specific
motor nameplate. Do not use the Unit nameplate values.
• A backup copy of the current setup may be saved to the LCP before changing
parameters or resetting the drive. See LCP Copy in the VFD Operating Instructions
for details.
Modify Parameters
Please refer to BAS-SVP16*-EN (TR150 and TR170 Programming Guide), or the most recent
version, for complete programming information.
