OPERATION
TO RESET VFD PARAMETERS TO FACTORY SETTINGS USING KEYPAD
The VFD will need to be unlocked as described on page 11 to reset Parameters to RenewAire factory or
ABB defaults.
To return to RenewAire’s defaults, select parameter 9902 APPLIC MACRO and press EDIT softkey. Scroll
down to USER 1 LOAD (Not USER 1 SAVE as this will overwrite the factory settings saved under USER 1 in
the VFD base memory). Press the SAVE softkey.
Alternatively, to return to RenewAire’s defaults, select PAR BACKUP in the keypad menu; scroll to and
select DOWNLOAD FULL SET (not UPLOAD TO PANEL as this will overwrite the factory settings saved in the
keypad memory).
To return to ABB’s defaults, select parameter 9902 APPLIC MACRO and press EDIT softkey. Scroll up or
down to select HVAC DEFAULT. Press the SAVE softkey. If HVAC DEFAULT was displayed without scrolling
after pressing EDIT in parameter 9902, you will need to scroll up to another macro numbered 2 through
15 and press SAVE, then scroll back down to 1=HVAC DEFAULT and press SAVE again to get the settings to
revert back to the original ABB defaults.
To save an edited parameter set for possible restoration, select parameter 9902 APPLIC MACRO and press
EDIT softkey. Scroll down to USER 2 SAVE (Not USER 1 SAVE as this will overwrite the factory settings
saved under USER 1 in the VFD base memory). Press the SAVE softkey. This edited parameter set can now
be reset using USER 2 LOAD.
The VFD should be relocked as described above after the desired parameter settings are entered to avoid
further, accidental changes to parameter settings.
NOTE:
VFD Manufacturer instructions list many other parameters. Copies of the complete manufacturer’s
instructions for the VFD are shipped with this unit, and are also available on-line in the Document Library
at www.abb.com/drives.

FUNCTION
2202
ACCELER TIME 1
30.0 s
30.0 s
Sets acceleration time.
2203
DECELER TIME 1
30.0 s
30.0 s
Sets deceleration time. This is ignored when 2102 STOP FUNCTION = COAST.
2607
SWITCH FREQ CONTROL 1=ON/2=ON (LOAD)
1=ON
Selects the control method for the switching frequency.
2609
NOISE SMOOTHING
0=DISABLED
0=DISABLED
Set to 1=enabled to activate the noise smoothing function. Noise smoothing lowers
peak noise intensity by distributing acoustic motor noise over a range of frequencies.
3007
MOT LOAD CURVE
100%
98% (TYP.)**
CRITICAL PARAMETER. Defi nes motor load curve.
3401*
SIGNAL 1 PARAM
103=OUTPUT FREQUENCY
101=SPEED AND DIR
Sets top line of keypad display to show motor speed in rpm.***
3408*
SIGNAL 2 PARAM
104=CURRENT
104=CURRENT
Sets middle line of keypad display to show motor current in Amps.***
3415*
SIGNAL 3 PARAM
120=AI 1
120=AI 1
Sets bottom line of keypad display to show value of analog signal input.***
* This parameter is not visible in the “short view”. To be able to view all signals and parameters, set parameter 1611 PARAMETER VIEW to 3 (LONG VIEW) on ACS320 VFDs.
** Parameter 2003 is set 125% for motors with 1.15 Service Factor (SF) or higher or otherwise protected and 115% for motors with less than 1.15 SF and otherwise
unprotected. Parameter 3007 is set 98% for motors wiht 1.15 SF or higher, 90% for motors with less than 1.15 SF and 100% for motors that are otherwise protected.
*** Numerous keypad operating data display options are listed in parameter Group 01.
**** Maximum Frequency set higher in LE units to generally operate motors near 60 Hz or faster resulting in higher motor output HP.
NOTE:
SPEED-SKIPPING is a function available through Parameters 2501-2507. It allows up to 3 critical speeds to be skipped as the VFD ramps speed up and down.
If noise problems occur at specifi c frequencies, Speed-Skipping may help. See the VFD manual for details.
