Main Circuit Terminal and Motor Wiring
This section outlines the various steps, precautions, and checkpoints for wiring the main circuit terminals and motor terminals.
NOTICE: When connecting the motor to the drive output terminals U/T1, V/T2, and W/T3, the phase order for the drive and motor should
match. Failure to comply with proper wiring practices may cause the motor to run in reverse if the phase order is backward.
NOTICE: Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Failure to comply could result in damage
to the drive, phase-advancing capacitors, LC/RC noise filters or ground fault circuit interrupters.
NOTICE: Do not connect the AC power line to the output motor terminals of the drive. Failure to comply could result in death or serious
injury by fire as a result of drive damage from line voltage application to output terminals.
n
Cable Length Between Drive and Motor
Voltage drop along the motor cable may cause reduced motor torque when the wiring between the drive and the motor is too
long, especially at low frequency output. This can also be a problem when motors are connected in parallel with a fairly long
motor cable. Drive output current will increase as the leakage current from the cable increases. An increase in leakage current
may trigger an overcurrent situation and weaken the accuracy of the current detection.
Adjust the drive carrier frequency according to Table 3.3. If the motor wiring distance exceeds 100 m because of the system
configuration, reduce the ground currents. Refer to C6-02: Carrier Frequency Selection on page 167.
