Setup Mode of the digital operator.
Setting 2: Advanced Access Level (A) and Setup Access Level (S)
All parameters can be viewed and edited.
Setting 3: Lock Parameters

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.

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.
