CAUTION
CONFIGURATION OVERRIDE HAZARD
Do not use ABB or Carrier start-up assistant on this VFD
application. Use of start-up assistant will override the factory
VFD configurations.
The following section details how to reset the VFD after acciden-
tally using Start-Up Assistant.
When the VFD has been incorrectly programmed by using Start-
Up Assistant, the drive may be locked in an override loop because
of motor ID Run Fail (error code 11) and First Start (error
code 2025).
Use the following procedure to reset the factory configurations for
ACS320 VFDs:
1.
Disconnect unit power. Lock-out/tag out.
2.
Remove the VFD's terminal cover.
3.
Disconnect the D11 input at terminal 12. The terminals are
numbered on the bottom of the block (see Fig. 55 for the
location of terminal block that contains terminal 12).
4.
Connect the VFD Keypad accessory to the VFD (if not
already connected).
NOTE: The VFD Keypad is a field-installed accessory; it is
not included with the factory-installed VFD option.
5.
Go immediately to parameter 1705 OVERRIDE ENABLE
and select "Off".
