Function Name Description Display Appears when torque command by the plug-in option is selected using Pr. Operation is freqro-a700 with the setting dial.

Page 62 Change the frequency at pulse train input. A brake unit is an option that fully enhances the regenerative braking capability of the inverter, and should be used with an electrical- discharge resistor.

Dedicated cable option Name type Specifications, Structure, etc. The cumulative power monitor data digit can be shifted to the right by the Free parameter number set in Pr. Saves energy since regeneration energy is used for the other inverters and excess energy is returned to the power supply.

Within 2-M12 eye nut 4-installation hole Safety Precautions are suspended in the air, and install the inverter in a clean place or To operate the inverter correctly and safely, be sure to read the put it in an ingress-protected “enclosed” Parameter List Parameter List For simple variable-speed operation of the inverter, the initial setting of the parameters may be used as they are.

Got it, continue to print. Page 79 Name type Specifications, Structure, etc. 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 commercial power supply.

Name Type Applications, Specifications, etc. 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. When installing the inverter in a compact enclosure, etc. FR-A series under real sensorless vector control Regeneration unit option is necessary for regeneration Page 68 Refer to the section about Pr.

There are six different brake units as in the following table, freqrll-a700 which make selection according to the deceleration time. Lit to indicate external operation mode.

Set the necessary parameters to meet the load and operational specifications. Don’t have an account? Page 21 Terminal Type Terminal Name Description Symbol 1 changeover contact output indicates that the inverter protective function has activated and Relay output 1 alarm the output stopped.

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. U, V, W Inverter output Connect a three-phase squirrel-cage motor. Page 77 Name type Specifications, Structure, etc. Selection of rated sensitivity current of earth ground leakage current breaker When using the earth leakage current breaker with the Selection example in the case of the left figure inverter circuit, select its rated sensitivity current as Breaker Designed For follows, independently of the PWM carrier frequency Standard Harmonic and Surge Eliminates the need to use a brake unit with each inverter, reducing total space and total cost.


In such a case, consider taking the following measures. Heatsink protrusion procedure When encasing the inverter in an enclosure, the generated heat amount in an enclosure can be greatly reduced by installing the heatsink portion of the inverter outside the enclosure.

Page 5 A personal computer and an Use within the permissible power inverter can be connected supply specifications of the inverter. When the frequency command is The brake unit and resistor unit are options that will fully exhibit the regenerative braking capability of the inverter.
