Inverter Function
12.9.2
Drive with V/f control (constant
torque characteristics)
• To use with a load for running conveyors and
bogies.
• To use in a fan/pump that changes its output
frequently.
• To avoid trips that may be likely to happen when
driven with reducing torque characteristics.
• To run multiple motors with a single inverter.
V/f control (constant torque characteristics)
•
With constant torque characteristics, the output
voltage is outputted proportionally to a given
command frequency along the straight line drawn
from the point 0 Hz/0 V to the intersection of the
base frequency and the rated voltage.
•
The output voltage corresponding to a frequency
range from 0 Hz to the base frequency is
determined proportionally to the given frequency,
but the output voltage corresponding to a
frequency range from the base frequency to the
maximum frequency is constant irrespective of the
frequency.
•
Use of the manual boost function renders the
output voltage higher than that on the basic
proportional line by the boost voltage.
The manual boost function is effective in the case
of low speeds and insufficient torque.
Parameter
• When a motor is hunting and vibrating, an
adjustment of the stability constant [HA110] may
improve the state of the motor.
• When a single inverter runs multiple motors and
the motors are vibrating, a downward adjustment of
the stability constant [HA110] may stabilize the
state of the motors.
