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 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.
b1-01 Frequency Reference Selection for AUTO Mode
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
used.
