YASKAWA V1000 Series

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.

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: Operation only
1: Preferred Parameters
2: Advanced Access Level (A) and Setup Access Level (S)
2
Detailed Description
0: Operation Only
Access is restricted to parameters A1-01, A1-04, A1-06, and all U monitor parameters.
1: Preferred Parameters
Access to only a specific list of parameters set to A2-01 through A2-32.
2: Advanced Access Level (A) and Setup Access Level (S)
All parameters can be viewed and edited.
• The drive parameters are password protected (A1-04), which prevents access to A1-00 through A1-03, A1-06, and all A2 parameters.
• A digital input is enabled that has been configured as a Program Lockout (H1-฀ ฀ = 1B).
• The display will show “bUSY” when attempting to change a parameter while writing to the drive via serial communications. Access will be restricted
from the operator keypad until an enter command is received via the serial communication to finish the serial writing process.
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: V/f Control without PG
2: Open Loop Vector
5: PM Open Loop Vector
0
Detailed Description
0: V/f Control without PG
• For general-purpose and multiple motor applications.
• For use when the parameter settings are unknown in the drive.
2: Open Loop Vector
• For general, variable-speed applications.
• For applications requiring precise speed control, quick response, and higher torque at low speeds.
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.
No. Parameter Name Setting Range Default
A1-03 Initialize Parameters
0: No Initialize
1110: User Initialize
2220: 2-Wire Initialization
3330: 3-Wire Initialization
5550: OPE04 Reset
0
Detailed Description
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”.
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.
3330: 3-Wire Initialization
The drive parameters are returned to factory default values with digital inputs S1, S2, and S5 configured as run, stop, and forward/reverse respectively.
