4.7 Basic Drive Setup Adjustments
This section explains the basic settings required for initial drive operation. Checking these basic parameter settings will help
to ensure a successful drive start-up. Refer to Parameter List on page 261 for a complete listing of drive parameters if more
information is required for parameters not listed in this section or in 4.13 Advanced Drive Setup Adjustments .
n 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. Parameter Name Setting Range Default
A1-02 Control Method Selection 0, 5 0
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 b1-01: Frequency Reference Selection for AUTO Mode
Selects the frequency reference source 1.
Note: If a Run command is input to the drive, but the frequency reference entered is 0 or below the minimum frequency, the AUTO or HAND
indicator LED on the HOA keypad will light and the OFF indicator will flash.
No. Parameter Name Setting Range Default
b1-01 Frequency Reference Selection for AUTO Mode 0 to 3 1
Setting 0: HOA Keypad
Using this setting, the frequency reference can be input by:
• switching between the multi-speed references from d1-01 to d1-04.
• entering the frequency reference on the operator keypad.
Setting 1: Terminals (Analog Input Terminals)
Using this setting, an analog frequency reference can be entered as a voltage or current signal from terminals A1 or A2.
Voltage Input
Voltage input can be used at any of the two analog input terminals. Make the settings as described in
Table 4.15 for the input
used.
