Descriptions
Connect a ground fault interrupter or MCCB to the power sup-
ply line to protect Inverter wiring and to prevent secondary
damage in the event of component failure. We recommend that
you use a ground fault interrupter as a general rule. However,
an MCCB can also be used if the power system supports the
use of an ELCB.
Install to prevent the braking resistor from burning out when
one is used. Always attach a surge absorber to the coil.
To protect internal components from sudden high levels of
input current, the MC should be wired so that it opens when a
*2
fault output terminal is triggered.
Absorbs surge from the magnetic contactor and control relays.
Connect surge absorbers to all magnetic contactors and relays
near the Inverter.
Isolates the I/O signals of the Inverter and is effective against
inductive noise.
Used to improve the input power factor of the Inverter. All
Inverters of 18.5 kW or higher contain built-in DC reactors.
These are optional for Inverters of 15 kW or less. Install DC
and AC reactors for applications with a large power supply
capacity (600 kVA or higher).
Reduces noise coming into the Inverter from the power supply
line and to reduce noise flowing from the Inverter into the
power supply line. Connect as close to the Inverter as possible.
Reduces noise from the line that sneaks into the Inverter input
power system. Insert as close to the Inverter as possible.
Can be use on both the input side and output side.
Reduces noise generated by the Inverter. Connect as close to
the Inverter as possible.
Consumes the regenerative motor energy with a resistor to
reduce deceleration time (use rate: 3% ED).
Consumes the regenerative motor energy with a resistor to
reduce deceleration time (use rate: 10% ED).
Used with a Braking Resistor Unit to reduce the deceleration
time of the motor.
Allows frequency reference settings and ON/OFF operation
control to be performed by analog references from a remote
location (50 m max.).
Frequency counter specifications: 60/120 Hz, 90/180Hz
Allows frequency reference settings and ON/OFF operation
control to be performed by analog references from a remote
location (50 m max.).
Frequency counter specifications: 75 Hz, 150 Hz, 220 Hz
Extension cable to use a Digital Operator remotely.
Cable length: 1 m or 3 m
A system controller that can be match to the automatic control
system to produce an optimum system configuration.
With this Unit, you can check Inverter user constants and the
error status even when the main circuit power supply is turned
OFF.
Handles momentary power losses for the control power supply
for models 7.5 kW or less (maintains power for 2 s).
Devices to set or monitor frequencies externally.
Measures the output voltage externally and designed for use
with a PWM Inverter.
Connected to the control circuit terminals to input a frequency
reference.
Calibrates the scale of frequency meters and ammeters.
