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.

A1-03: Initialize Parameters

Resets parameters to default values. After initialization, the setting for A1-03 automatically returns to 0.

No.

Parameter Name

Setting Range

Default

A1-03

Initialize Parameters

0, 1110, 2220,

3330, 3410, 3420

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 to default settings with digital inputs S1 and S2 configured as Forward run and Reverse run, respectively.

Refer to Setting 40, 41: Forward Run, Reverse Run Command for 2-Wire Sequence on page 78

for more information on

digital input functions.

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.

Refer to Setting 0: 3-Wire Sequence on page 73

for more information on digital input functions.

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 (BP Emergency Override)
H1-06: AE (BP Bypass Run)
H2-01: A4 (BP Drive Relay)
H2-02: A5 (BP Bypass Relay)
H2-03: A6 (BP BAS Interlock)
o1-16: 2 (Drive/Bypass)

Note:

After performing an OEM Bypass Initialization, H1-03 to H1-05, H2-01 to H2-03, and o1-16 will be displayed in the Modified Parameters

list.

Notes on Parameter Initialization

The parameters shown in

Table 1.1

will not be reset when the drive is initialized by setting A1-03 = 2220 or 3330. Although

the control mode in A1-02 is not reset when A1-03 is set to 2220 or 3330, it may change when an application preset is selected.
