Wiring (1) Cable size and other specifications of the main circuit terminals and the earthing terminal Select the recommended cable size to ensure that a voltage drop will be 2% at maximum. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency. The following table indicates a selection example for the wiring length of 20m.
Wiring The line voltage drop can be calculated by the following formula: 3 × wire resistance[mΩ/m] × wiring distance[m] × current[A] 1000 Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque Line voltage drop [V]= reduction) in the low speed range. (2) Total wiring length The overall wiring length for connection of a single motor or multiple motors should be within the value in the table below. Pr.

Strip off the sheath about the length below. If the length of the sheath peeled is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off.
Wiring (1) Control circuit common terminals (SD, 5, SE) Terminals SD, SE and 5 are common terminals for I/O signals. (All common terminals are isolated from each other.) Do not earth them. Avoid connecting the terminals SD and 5 and the terminals SE and 5. Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL, MRS, RES) and frequency output signal (FM). The open collector circuit is isolated from the internal control circuit by photocoupler.

PRECAUTIONS FOR USE OF THE INVERTER 3 PRECAUTIONS FOR USE OF THE INVERTER The FR-E700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following points. (1) Use crimping terminals with insulation sleeve to wire the power supply and motor. (2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter.
PRECAUTIONS FOR USE OF THE INVERTER (11) Across terminals P/+ and PR, connect only an external regenerative brake discharging resistor. Do not connect a mechanical brake. The brake resistor can not be connected to the 0.1K(SC) or 0.2K(SC). Leave terminals P/+ and PR open. Also, never short between these terminals. (12) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.
