Mitsubishi VFD D700

Mitsubishi frequency inverter FR-D700 - new standard of inverter.

Safety stop function.
The FR-D700 series is compliant to the EU Machinery Directive without the addition of previously required external devices. Operation of an external Emergency Stop device results in a highly reliable immediate shutoff of the D700's output to the motor. This safety stop function conforms to the following standards.

Spring clamp terminal (control circuit terminal).
- Easy wiring.
Wiring is completed only by inserting wires treated with bar terminal (max, diameter 1.5mm) Capable of wiring without a bar terminal.
- High reliability.
Spring structure in terminal contact section inside prevents contact fault by vibration.
- Maintenance is unnecessary.
Screw retightening is unnecessary.
Long-life design.
- The design life of the cooling fan has been extended to 10 years. The life of the fan can be further extended utilizing the it’s ON/OFF.
- The longevity of the capacitors has been extended to 10 years by the adoption of a capacitor with a specification of 5000 hours and 105˚C surrounding air temperature.
Most advanced life check. 
- Degrees of deterioration of main circuit capacitor, control circuit capacitor, and inrush current limit circuit can be monitored.
- Trouble can be avoided with the self-diagnostic alarm*4 that is output when the life span is near.
Password function.
Registering 4-digit password can limit parameter read/write. It is effective for parameter setting protection.

Mitsubishi drive FR-D700 series is equipped with small class highest level of function/performance.

150%/1Hz high starting torque by general -purpose magnetic flux vector control.
General-purpose magnetic flux vector control and auto tuning function are available. It ensures operation that requires high starting torque, such as transfer machine including conveyer, hoist, lift, etc., washing machine, and agitators.
- High torque 150%/1Hz and 200%/3Hz are realized
- Auto tuning Many kinds of motors can be optimally controlled with Mitsubishi original "non-rotation " auto tuning function. (R1 constants tuning)

Brake resistor can be connected.
A brake transistor is built-in to the 0.4K or more. Connecting an optional brake resistor increases regeneration capability. It is useful for deceleration time reduction of a machine with a large inertia, such as fan, and operation of lift, etc.
Regeneration avoidance function.
For a pressing machine and fan rotated faster than the set speed due to the effect of another fan, a trip can be made less likely to occur by automatically increasing frequency at regeneration.
Optimum excitation control.
This control enables the motor efficiency to its optimum. More energy saving is possible in applications with variable load torque characteristic such as fan and pump.
Power failure-time deceleration-to-stop function.
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.
Dancer control.
Entering position detection signal of dancer roll to use PID control enables tension control by dancer roll.
Traverse function.
Traverse function for wind-up drum of spinning machine and wiredrawing machine prevents unevenness and deformation at thread winding.

Easy use and time saving build in as standard in Mitsubishi vfd FR-D700 series.

Quick setup with the setting dial.
Mitsubishi inverter has a setting dial of course.
- The scrolling speed of the dial was made to variable for more improved operability. ,
- The nonslip setting dial is easier to turn.
Setting is easily done from a personal computer using the FR Configurator (option) (available soon).
Connecting a personal computer and the inverter via RS-485 communication realizes setting with wizard (interactive) function of the FR Configurator (inverter setup software). In addition, a parameter setting can be converted from the FRS500 series to the FR-D700 series by "convert" function. Displays monitor data in waveform. [Graph]

Enclosure surface operation panel FR-PA07 (option).
Optional enclosure surface operation panel (FR-PA07) can be connected. In addition, an operation panel for the FR-E500 series can be connected.
Parameter unit FR-PU07 (option).
An optional parameter unit (FR-PU07) can be connected as well.
- Setting such as direct input method with a numeric keypad, operation status indication, and help function are usable. Eight languages can be displayed.
- Parameter setting values of maximum of three inverters can be stored.
- A battery pack type (FR-PU07BB(-L)) allows parameter setting and parameter copy without powering on the inverter. (available soon)
- To use a parameter unit with battery pack (FR-PU07BB) outside Japan, order a “FR-PU07BB-L” (parameter unit type indicated on the package has L at the end). Since enclosed batteries may conflict with laws in countries to be used (new EU Directive on batteries and accumulators, etc.), batteries are not enclosed with an FR-PU07BB except Japan.
Enhanced communication function.
Modbus and Mitsubishi inverter protocol Supports Modbus RTU Communication speed of RS-485 has been improved (communication at 38.4kbps is available) "Multi command mode" has been added to Mitsubishi inverter protocol (data processing time of the inverter has been reduced to 1/4).

Easy maintenance with Mitsubishi frequency inverter FR-D700.

Easy replacement of cooling fan.
A cooling fan is provided on top of the inverter of all capacities requiring a cooling fan (1.5K or more). A cooling fan can be easily replaced without disconnecting main circuit wires.
Combed shaped wiring cover.
Since a cover can be fitted after wiring, wiring work is easily done.
