Rated. / 5. Based on customer reviews
For the 75K or more, a
DC reactor is supplied.
Always install the reactor.
* The inverter may trip and the motor may coast depending on the load condition.
Tuning accuracy equivalent to that of the conventional tuning of
“with rotation mode” is realized with the auto tuning without
motor running. Even for the machine which disallows a motor to
run during tuning, the motor performance can be maximized.
The sophisticated auto tuning function which measures circuit constants
of the motor allows sensorless vector control with any kind of motor.
•
The motor can be decelerated to a stop when a power failure
or undervoltage occurred to prevent the motor from coasting.
For fail-safe of machine tool, etc., it is effective to stop the
motor when a power failure has occurred.
•
Since the original operation continuation at instantaneous
power failure function has been newly adopted, the motor
continues running without coasting even if an instantaneous
power failure occurs during operation.
For operations of such as a pressing machine, in which an
instantaneous regeneration occurs, overvoltage trip can be
made less likely to occur by increasing frequency during
regeneration.
Speed command by pulse train signal (single pulse) from the
controller etc. can be directly input to the inverter.
Since pulse can be output from the inverter at the same time,
synchronous speed operation of inverters can be performed.
(maximum pulse input 100kpps, output 50kpps)
•
For the analog input terminal (two points), you can switch
between voltage (0 to 5V, 0 to 10V) and current (0 to 20mA).
•
You can display the ON/OFF status of the I/O terminals on the
operation panel.
•
Two points relay output is available.
Compliance with both 240V power supply (55K or less) and
480V power supply as standard.
In addition to the 0.4K to 7.5K, a brake transistor is built-in to the
11K, 15K, 18.5K and 22K. A brake resistor (option) can be also
connected to the 11K to 22K.
The 55K or less has
a built-in zero-phase
reactor.

Install a noise filter to reduce
the electromagnetic noise
generated from the inverter.
Effective in the range from
about 1MHz to 10MHz. A wire
should be wound four turns at
a maximum.
Use within the permissible power
supply specifications of the inverter.
The breaker must be selected
carefully since an in-rush current
flows in the inverter at power on.
Install the magnetic contactor to
ensure safety. Do not use this
magnetic contactor to start and stop
the inverter. Doing so will cause the
inverter life to be shorten.
Reactors (option) must be used when
power harmonics measures are
taken, the power factor is to be
improved or the inverter is installed
near a large power supply system
(1000kVA or more). The inverter may
be damaged if you do not use
reactors. Select the reactor according
to the model. Remove the jumpers
across terminals P-P1 to connect the
DC reactor to the 55K or less.
Do not install a power factor correction
capacitor, surge suppressor or radio noise
filter on the output side of the inverter. When
installing a moulded case circuit breaker on
the output side of the inverter, contact each
manufacturer for selection of the moulded
case circuit breaker.
To prevent an electric shock, always earth
(ground) the motor and inverter. For
reduction of induction noise from the power
line of the inverter, it is recommended to wire
the earth (ground) cable by returning it to the
earth (ground) terminal of the inverter.

Power supply harmonics
can be greatly suppressed.
Install this as required.
Power regeneration

)
Great braking capability
is obtained.
Install this as required.
The regenerative braking
capability of the inverter
can be exhibited fully.
Install this as required.
*3
Braking capability of the
inverter built-in brake can be
improved. Remove the jumper
across terminal PR-PX when
connecting the high-duty
brake resistor. (7.5K or less)
A personal computer and an
inverter can be connected
with a USB (Ver1. 1) cable.
