◆ Main Circuit Terminal Power Supply 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. Improper application of noise filters
could result in damage to the drive.
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.
Cable Length Between Drive and Motor
■
When the cable length between the drive and the motor is too long (especially at low frequency output), note that the
cable voltage drop may cause reduced motor torque. 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 the following table. If the motor wiring distance exceeds 100 m because
of the system configuration, reduce the ground currents.
Refer to Table 3.5 to set the carrier frequency to an appropriate level.

Carrier Frequency
Note: When setting carrier frequency, calculate the cable length as the total distance of wiring to all connected motors when running
multiple motors from a single drive.
