MITSUBISHI ELECTRIC CORPORATION
FREQROL-A700 Series General-purpose inverter |
|
|
 |
|
Highest level in your hand
High-performance/high-function inverter |
| |
| Features |
|
| ● |
Performance Enhancement
- High accuracy/fast response speed operation by the vector control can be performed with a general-purpose motor without encoder.
Also permits torque limits during torque control and speed control.
- Vector control operation can be performed using a motor with encoder.
Torque control/position control as well as zero speed control, servo lock can be realized with the inverter.
|
| ● |
Improved Reliability & Maintainability
- Lengthens the life of cooling fans and capacitors.
- A self-diagnosis function outputs parts life alarm and monitors degrees of deterioration, permitting corrective measures to be taken before problems occur.
- A removable terminal block and cooling fan cassette simplify replacement procedures.
|
| ● |
Environment Friendly
- A newly developed, built-in noise filter (EMC filter) reduces noise emissions from the inverter.
|
| ● |
Easy to Use
- When CC-Link is running, operation can be controlled by X, Y commands from a PLC, making program creation easy.
