Setting 3: Lock Parameters
Parameters that are normally visible in the advanced access level (A1-01 = 2) are still visible, but the only parameters that can
be changed are A1-01 and A1-04.
The Auto Tuning and Pump Quick Setup menus will not be displayed.

Notes on Parameter Access
• If the drive parameters are password protected by A1-04 and A1-05, parameters A1-00 through A1-03, A1-06, and all A2
parameters cannot be modified.
• If a digital input terminal programmed for “Program lockout” (H1-oo = 1B) is enabled, parameter values cannot be
modified, even if A1-01 is set to 1 or 2.
• If parameters are changed via serial communication, it will not be possible to edit or change parameter settings with the
digital operator until an Enter command is issued to the drive from the serial communication.
n A1-03: Initialize Parameters
Resets parameters to default values or performs an Application Preset for fan or pump applications. After initialization, the
setting for A1-03 automatically returns to 0.
No. Parameter Name Setting Range Default
A1-03 Initialize Parameters
0, 1110, 2220, 3330, 5550,
6008, 6009, 7770, 7771
0
Setting 1110: User Initialize
Resets parameters to the values selected by the user as User Settings. User Settings are stored when parameter o2-03 is set to
“1: Set defaults”.
Note: User Initialization resets all parameters to a user-defined set of default values previously saved to the drive. Set parameter o2-03 to 2 to
clear the user-defined default values.
Setting 2220: 2-Wire Initialization
Resets parameters to default settings with digital inputs S1 and S2 configured as Forward run and Reverse run, respectively.
Setting 3330: 3-Wire Initialization
Resets parameters to default settings with digital inputs S1, S2, and S5 configured as Run, Stop, and Forward/Reverse
respectively.
