12.1 A: INITIALIZATION
530 SIEPYEUOQ2A01G AC Drive Q2A Technical Manual
This is a control method for induction motors. Use this control method for applications in which high-precision
speed control is necessary.
This control method has high speed and torque response and high torque when operating at low speeds. The speed
control range is 1:200.
5 : PM OLVector
The drive controls an IPM motor or SPM motor in this control method. Use this control method for general
variable-speed control applications in which a high level of responsiveness or high-precision speed control are not
necessary. The speed control range is 1:20.
6 : PM AOLVector
The drive can control an IPM motor in this control method. Use this control method for general variable-speed
control applications in which high-precision speed control and torque limit are necessary. The speed control range
is 1:20. The speed control range is 1:100 when
n8-57 = 1 [High-Freq Injection = Enabled] .
7 : PM CLVector
The drive controls a PM motor in this control method. Use this control method for constant torque applications in
which high-precision control with a PM motor is necessary. Also use this control method for general variable-
speed control applications in which high torque response and high-precision torque control are necessary. A speed
feedback signal from the motor is necessary for this control method. The speed control range is 1:1500.
8 : EZ Vector
The drive controls induction motors and PM motors in this control method. This control method uses an easier
procedure to operate motors with more efficiency. Use this control method for derating torque applications. For
example, fans and pumps.

A1-03
(0103)
Init Parameters
Sets parameters to default values.
0
(0 - 9990)
Note:
• After you initialize the drive, the drive automatically sets A1-03 = 0 .
•
User Parameters can save the parameter values for your application and use these values as default values for drive initialization.
•
To use the 2 motor switchover function, first turn OFF the terminal to which H1-xx: MFDI Function Select = 61 [Motor 2 Select] is
set, then change the A1-02 setting. An incorrect procedure will trigger oPE08 [Parameter Selection Error] .
0 : No Initialization
1110 : User Initialization
Sets parameters to the values set by the user as user settings. Set o2-03 = 1 [UserPar Set Default Values = Set
defaults] to save the user settings.
You can save the parameter settings that were adjusted for the test run as user-set default values to the drive. Set
A1-03 = 1110 to reset to the saved parameter settings.
Follow this procedure to save User Parameter setting values, and to do a User Initialization.
1. Set parameters correctly for the application.
2. Set
o2-03 = 1 [UserPar Set Default Values = Set defaults] .
This saves parameter settings for a User Initialization.
The drive will then automatically set
o2-03 = 0 .
3. When you make changes to the parameter values after you save the settings as User Parameter Settings, the
drive will set the parameters to the User Parameter Setting value when you initialize with A1-03 = 1110 .
When you initialize the drive, the drive sets the parameter values to the User Parameter setting values.
2220 : 2-Wire Initialization
Sets MFDI terminal DI1 to Forward Run and terminal DI2 to Reverse Run, and resets all parameters to default
settings.
3330 : 3-Wire Initialization
Sets MFDI terminal DI1 to Run, terminal DI2 to Stop, and terminal DI5 to FWD/REV, and resets all parameters to
default settings.
4440 : Q2pack Init
The drive will not initialize the parameters in Table 12.2 when A1-03 = 2220, 3330 .
