Mitsubishi Electric FR-A700 Manual
Parameter setting, change and check can be made from the operation panel FR-DU Page 87 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. There are six different brake units as in the following table, from which make selection according to the deceleration time.
Lit to indicate PU operation mode.
Inverter-driven V class motor When driving a V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. Saves energy since regeneration energy is used for the other inverters and excess energy is returned to the power supply.
Excitation ratio Refer to the section about Pr. Page manuall to to Function assignment of input terminal Terminal assignment of output terminal Pr. Geared Motor Inverter-driven V class motor When driving a V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.
Motor Torque Application to Motor Freqrol-aa700 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 commercial power supply.
A brake unit and resistor unit are options that will fully exhibit the regenerative braking capability of the inverter and are always used as a set.
Page freqrol-700 Change the frequency at pulse train input. Protective Functions When an alarm occurs in the manuwl, the protective function is activated bringing the inverter to an alarm stop and the PU display automatically changes to any of the following error alarm indications. Page 4 Operation is easy with the setting dial. Set the necessary parameters to meet the load and operational specifications.
