Page 81 Name type Specifications, Structure, etc. Application of the sine wave filter For the FR-A series 75K or more inverter, the motor voltage and current can be made to nearly sine wave shaped by providing a sine wave filter on freqrrol-a700 output side. Parameter setting, change and check can be made from the operation panel FR-DU This parameter may be only set if Pr.
There are six different brake units as in the following table, from which make selection according to the necessary braking torque and deceleration time.
Motor Torque Application to Motor Application to standard motors Motor loss and temperature rise Vibration The motor operated by the inverter has a limit on the The machine-installed motor operated by the inverter may be continuous operating torque since it is slightly higher in slightly greater in vibration than the one driven by the temperature rise than the one operated by a commercial power msnual power supply.
Precautions for selection Inverter capacity selection When operating a special motor or more than one motor in parallel with a single inverter, select the inverter capacity so that 1. Don’t show me this message again.
