A1-02: Control Method Selection
Selects the Control Method (also referred to as the control mode) that the drive uses to operate the motor. Parameter A1-02
determines the control mode for the motor.
Note:
When changing control modes, all parameter settings depending upon the setting of A1-02 will be reset to the default.
No.
A1-02
Setting 0: V/f Control for Induction Motors
Use this mode for simple speed control and for multiple motor applications with low demands to dynamic response or speed
accuracy. The speed control range is 1:40.
Setting 5: Open Loop Vector Control for PM
Use this mode when running a PM motor in variable torque applications that benefit from energy efficiency. The drive can
control an SPM or IPM motor with a speed range of 1:20 in this control mode.
n
A1-03: Initialize Parameters
Resets parameters to default values. After initialization, the setting for A1-03 automatically returns to 0.
No.
A1-03
Setting 0: No Initialize
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.
Setting 2220: 2-Wire Initialization
Resets parameters except parameters listed in
run and Reverse run, respectively.
Setting 3330: 3-Wire Initialization
Resets parameters to default settings with digital inputs S1, S2, and S5 configured as Run, Stop, and Forward/Reverse
respectively.
Setting 3410: HVAC Initialization
Resets parameters to default settings. The following parameters are not reset:
H1-03: b1 (Customer Safeties)
H1-04: b2 (BAS Interlock)
H1-05: AF (Emergency Override Forward Run)
H2-03: b2 (BAS Interlock Relay Contact)
Note:
After performing an HVAC Initialization, H1-03 to H1-05 and H2-03 will be displayed in the Modified Parameters list.
Setting 3420: OEM Bypass Initialization
Resets parameters to default settings. The following parameters are not reset:
H1-03: A7 (BP Customer Safeties)
H1-04: A6 (BP BAS Interlock)
H1-05: A4 (Emergency Override)
H1-06: AE (BP Bypass Run)
H2-01: A4 (BP Drive Relay)
H2-02: A5 (BP Bypass Relay)
