Main Circuit Wiring

This section describes the functions of the main circuit terminals, and the specifications, and procedures required to
safely and properly wire the main circuit in the drive.
NOTICE: Do not solder the ends of wire connections to the drive. Soldered wiring connections can loosen over time. Improper wiring
could result in drive malfunction due to loose terminal connections.

◆ Main Circuit Terminals (Common to All Capacities)

Input Terminals
■
Terminal Code Terminal Name
R Main circuit phase-R input
S Main circuit phase-S input
T Main circuit phase-T input
Output Terminals
■
Terminal Code Terminal Name
U Main circuit phase-U output
V Main circuit phase-V output
W Main circuit phase-W output
NOTICE: Do not short circuit the drive output terminals or connect the power supply lines to output terminals U, V and W of the drive.
Incorrect wiring can result in damage to the drive. Carry out wiring that conforms to the wire gauges and tightening torques
described in this manual. Conduct a thorough check of wiring and sequences before turning the power on.
NOTICE: Select a main circuit power supply with a capacity larger than that of the drive to be connected. Inputs and outputs of the
drive (main circuit) contain harmonic components that may adversely affect communication devices, such as AM radios,
used in the vicinity. Use high-voltage cables and ground any shielded cables. Separate cables for control from high-current
circuits (main circuit and relay sequence circuits) to avoid induction from peripheral devices. (It is advisable to separate them
by a distance of 30 cm or more.)
