5.1 A: Initialization
The initialization group contains parameters associated with initial setup of the drive. Parameters involving the display
language, access levels, initialization, and password are located in this group.
u
A1: Initialization
n
A1-01: Parameter Access Level
Allows or restricts access to drive parameters.
No.
Parameter Name
Setting Range
Default
A1-01
Access Level Selection
0 to 2
2
Setting 0: Operation Only
Access is restricted to parameters A1-01, A1-04, A1-06, and all U monitor parameters.
Setting 1: User Parameters
Access to only a specific list of parameters set to A2-01 through A2-32. These User Parameters can be accessed using the
Setup mode of the digital operator.
Setting 2: Advanced Access Level (A) and Setup Access Level (S)
All parameters can be viewed and edited.
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 programmed for Program Lockout (H1-
= 1B) is enabled, parameter values can not be modified,
even though the A1-01 is set to 1 or 2.
• If parameters are changed via serial communication the parameters can not be changed from the digital operator until
an Enter command is received from the serial communication.
n
A1-02: Control Mode Selection
Selects the Control Method of the drive.
No.
Parameter Name
Setting Range
Default
A1-02
Control Method Selection
0, 2, 5
0
Setting 0: V/f Control
• For general-purpose and multiple motor applications.
• For use when the motor parameters are unknown and Auto-tuning can not be performed.
Setting 2: Open Loop Vector
• For general, variable-speed applications.
• For applications requiring precise speed control, quick response, and higher torque at low speeds.
Setting 5: PM Open Loop Vector
For operating SPM, IPM, and various permanent magnet motors. Takes advantage of Energy Saving features when
operating with derated torque.
n
A1-03: Initialization
Resets parameter settings back to their original default values. After the initialization the parameter automatically returns
to 0.
No.
Parameter Name
Setting Range
Default
A1-03
Initialize Parameters
0, 1110, 2220, 3330, 5550
0
Setting 0: No Initialize
Setting 1110: User Initialize
The modified drive parameters are returned to the values selected as user settings. User settings are stored when parameter
o2-03 = “1: Set Defaults”.
Note:
A “user-initialization” resets all parameters to a user-defined set of default values that were previously saved to the drive. To clear the
user-defined default values, set parameter o2-03 to “2”.
Setting 2220: 2-Wire Initialization
Resets all parameters back to their original default settings with digital inputs S1 and S2 configured as forward run and
reverse run, respectively.
