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.
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
system configuration, reduce the ground currents.
Cable Length
Carrier Frequency
Note: When setting carrier frequency in a drive running multiple motors, calculate the cable length as the total distance of wiring to all
motors that are connected.
