FR-D720S-025-EC - Frequency inverter - MITSUBISHI

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.

•The design life of the cooling fan has been extended to 10 years*1. The life of the fan can be further extended utilizing the it’s ON/OFF control.
•The design life of the capacitors has been extended to 10 years by the adoption of a capacitor endures 5000 hours at 105 ̊C surrounding air temperature.

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 of 150%/1Hz and 200%/3Hz (3.7K or less) is realized (when the slip compensation function is valid).
•Auto tuning
Many kinds of motors can be optimally controlled with Mitsubishi original "non-rotation" auto tuning function. (R1 constants tuning).

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.

New functions and useful functions from superior models support all sorts of applications.

• Regeneration avoidance function
For a pressing machine and fan rotated faster than the set speed due to the effect of another fan, a trip is 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 occur to prevent the motor from coasting.
For fail-safe of machine tool, etc., it is effective to stop the motor when a power failure occurs.

• 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.
