Setting 2: Open Loop Vector Control
Use this mode for general, variable-speed applications that require precise speed control, quick torque response, and high
torque at low speed without using a speed feedback signal from the motor.
Note: To set up single channel encoder feedback to the drive usnig the pulse train input for simple closed loop control,

A1-03: Initialize Parameters
Resets parameters back to the original default values. After initialization, the setting for A1-03 automatically returns to 0.
No.

Setting 0: No initialization
Setting 1110: User Initialize
Drive parameters are reset to 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 all parameters back to their original default settings with digital inputs S1 and S2 configured as Forward run and
Reverse run, respectively.
Setting 5550: oPE04 Reset
An oPE04 error appears on the digital operator when a terminal block with settings saved to its built-in memory is
installed in a drive that has edited parameters. Set A1-02 to 5550 to use the parameter settings saved to the terminal block
memory.

A1-04, A1-05: Password and Password Setting
Parameter A1-04 enters the password when the drive is locked; parameter A1-05 is a hidden parameter that sets the
password.
No.

A1-05
How to use the Password
The user can set a password in parameter A1-05 to restrict access to the drive. The password must be entered to A1-04 to
unlock parameter access (i.e., parameter setting A1-04 must match the value programmed into A1-05). The following
parameters cannot be viewed or edited until the value entered to A1-04 correctly matches the value set to A1-05: A1-01,
A1-02, A1-03, A1-06, and A2-01 through A2-33.
The instructions below demonstrate how to set password "1234". An explanation follows on how to enter that password
to unlock the parameters.
