Precautions for Correct Use
• When a motor is hunting and vibrating, an adjustment of the stabilization constant, 1st-motor
[HA110] may improve the state of the motor.
• The frequencies set by free V/f set-up have to always meet the following requirement: f1 ≤ f2
≤ f3 ≤ f4 ≤ f5 ≤ f6 ≤ f7 ≤ base frequency. The initial value for each of the frequencies set by
the free V/f set-up is 0 Hz. Set the maximum frequency and the base frequency first, and
then set the frequencies f7, f6, f5, f4, f3, f2, and f1 in this order by the free V/f set-up.
• Setting the [AA121] at 02 (free V/f set-up) disables the manual torque boost operational
mode selection, 1st-motor [Hb140].
• Default data of frequency for Free V/f setting is 0Hz. Even when you set Control mode
selection, 1st-motor [AA121] to 02 ([V/f] Free V/f (IM)), you can not operate an inverter. Be
sure to set the frequency for Free V/f setting.
