Installation manual

● A short circuit or earth fault on the inverter output side may damage the
inverter modules.
– Fully check the insulation resistance of the circuit prior to inverter oper-
ation since repeated short circuits caused by peripheral circuit inade-
quacy or an earth fault caused by wiring inadequacy or reduced motor
insulation resistance may damage the inverter modules.
– Fully check the to-earth insulation and inter-phase insulation of the
inverter output side before power-on.
Especially for an old motor or use in hostile atmosphere, securely check
the motor insulation resistance etc.
● Do not use the inverter input side magnetic contactor to start/stop the
inverter. Always use the start signal (ON/OFF of STF and STR signals) to
start/stop the inverter.
● Across + and PR terminals, connect only an external regenerative brake dis-
charge resistor. Do not connect a mechanical brake.
The brake resistor can not be connected to the FR-D720S-008 and 014.
Leave terminals + and PR open.
Also, never short between + and PR.
● Do not apply a voltage higher than the permissible voltage to the inverter
I/O signal circuits.
Application of a voltage higher than the permissible voltage to the inverter
I/O signal circuits or opposite polarity may damage the I/O devices. Espe-
cially check the wiring to prevent the speed setting potentiometer from
being connected incorrectly to short terminals 10-5.
● Provide electrical
and mechanical
interlocks for MC1
and MC2 which are
used for bypass
operation.
When the wiring is
incorrect or if there
is a bypass circuit
as shown on the right, the inverter will be damaged by leakage current
from the power supply due to arcs generated at the time of switch-over or
chattering caused by a sequence error.
● If the machine must not be restarted when power is restored after a power
failure, provide a magnetic contactor in the inverter's input side and also
make up a sequence which will not switch on the start signal. If the start sig-
nal (start switch) remains on after a power failure, the inverter will automat-
ically restart as soon as the power is restored.
● Instructions for overload operation
When performing operation of frequent start/stop of the inverter,
increase/decrease in the temperature of the transistor element of the
inverter may repeat due to a continuous flow of large current, shortening
the life from thermal fatigue. Since thermal fatigue is related to the amount
of current, the life can be increased by reducing bound current, starting
current, etc. Decreasing current may increase the life. However, decreasing
current will result in insufficient torque and the inverter may not start.
Therefore, increase the inverter capacity to have enough allowance for cur-
rent.
● Make sure that the specifications and rating match the system require-
ments.
● When the motor speed is unstable, due to change in the frequency setting
signal caused by electromagnetic noises from the inverter, take the follow-
ing measures when applying the motor speed by the analog signal.
– Do not run the signal cables and power cables (inverter I/O cables) in
parallel with each other and do not bundle them.
– Run signal cables as far away as possible from power cables (inverter I/
O cables).
– Use shield cables as signal cables.
– Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

NOTES
● Tighten the terminal screw to the specified torque. A screw that has been
tightened too loosely can cause a short circuit or malfunction. A screw that
has been tightened too tightly can cause a short circuit or malfunction due
to the unit breakage.
● Use crimping terminals with insulation sleeve to wire the power supply and
motor.
