Consideration of peripheral equipment, and a full range of protective functions!
!
You can use an inverter equipped with functions like these
!
If your control panel is designed to use multiple inverters,
these inverters make it possible to save space through their
horizontal side-by-side installation. (5HP or smaller models)
Previous energy saving operation functions worked only to
control the motor's loss to keep it at a minimum in accordance
with the load condition. In the newly developed FRENIC-Multi
Series, the focus has been switched away from the motor
alone to both the motor and the inverter as electrical products.
As a result, we incorporated a new control system (optimum
and minimum power control) that minimizes the power
consumed by the inverter itself (inverter loss) and the loss of
the motor.
When FRENIC-Multi Series (including FRENIC-Mini Series,
FRENIC-Eco Series and 11 Series) is used, the built-in resistor
suppresses the inrush current generated when the motor starts.
Therefore, it is possible to select peripheral equipment with
lower capacity when designing your system than the equipment
needed for direct connection to the motor.
Side-by-side mounting saves space!
Resistors for suppressing inrush current are built in, making it
possible to reduce the capacity of peripheral equipment.
The mounting adapter for external cooling (option) can be
installed easily as an outside panel cooling system.
Outside panel cooling is also made possible using
the mounting adapter for external cooling (option).
Smooth starts through the pick-up function!
In the case where a fan is not
being run by the inverter but
is turning free, the fan's
speed is checked, regardless
of its rotational direction, and
operation of the fan is picked
up to start the fan smoothly.
This function is convenient in
such cases as when
switching instantaneously
from commercial power
supply to the inverter.
Equipped with a full range of PID control functions!
Differential alarm and absolute value alarm outputs have been
added for PID adjusters which carry out process controls such as
temperature, pressure and flow volume control. In addition, an
anti-reset windup function to prevent PID control overshoot and
other PID control functions which can be adjusted easily through
PID output limiter, integral hold/reset signals are provided. The
PID output limiter and integral hold/reset signals can also be
used in cases where the inverter is used for dancer control.
Continuous equipment operation with overload avoidance control!
If foreign matter gets wrapped around a fan or pulley and the
load increases, resulting in a sudden temperature rise in the
inverter or an abnormal rise in the ambient temperature, etc.
and the inverter becomes overloaded, it reduces the motor's
speed, reducing the load and continuing operation.
An overload stop function protects equipment from over-operation!
If the load on equipment
suddenly becomes great
while controlled by the
inverter, the inverter can
be switched to
deceleration stop or to
coast-to-stop operation to
prevent damage to the
equipment.
Operating signal trouble is avoided by the command loss detection function!
New system for more energy-efficient operation!
If frequency signals connected to the inverter (0 to 10V, 4 to
20mA, Multi-speed signals, communications, etc.) are
interrupted, the missing frequency commands are detected as a
"command loss." Further, the frequency that is output when
command loss occurs
can be set in
advance, so operation
can be continued
even in cases where
the frequency signal
lines are cut due to
mechanical vibrations
of the equipment, etc.
