Connection with Peripheral Devices Peripheral devices necessary for driving the FR-F700 series inverter are indicated below. Inverter (FR-F700) Three-phase AC power supply Use within the permissible power supply specifications of the inverter. (Refer to page 7.) The life of the inverter is influenced by ambient temperature. The ambient temperature should be as low as possible within the permissible range. (Refer to page 8.) This must be noted especially when the inverter is installed in an enclosure.
The load torque of a motor-driven machine generally changes depending on speed. On the other hand, motor output is proportional to the product of load torque and speed as indicated in the following formula, and therefore, necessary motor output varies with speed.

Precautions for Operation/Selection Precautions for use of the inverter Safety Precautions To operate the inverter correctly and safely, be sure to read the "instruction manual" before starting operation. This product has not been designed or manufactured for use with any equipment or system operated under life-threatening conditions.
Precautions for Peripheral Device Selection 300m 200m 500m 300m 500m 500m Use the recommended connection cable when installing the operation panel away from the inverter unit or when connecting the parameter unit. For remote operation via analog signal, wire the control cable between the operation box or operation signal and inverter within 30m and away from the power circuits (main circuit and relay sequence circuit) to prevent induction from other devices.
Line leakage current Noise When performing low-noise operation at higher carrier frequency, electromagnetic noise tends to increase. Therefore, refer to the following measure example and consider taking the measures. Depending on the installation condition, the inverter may be affected by noise in a non-low noise (initial) status. The noise level can be reduced by decreasing the carrier frequency (Pr. 72).
