[Wiring]
CAUTION
●
Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly.
●
Make sure to connect the cables and connectors by using the fixing screws and the locking
mechanism. Otherwise, the cables and connectors may be disconnected during operation.
●
Do not install a power capacitor, surge killer, or radio noise filter (optional FR-BIF(-H)) on the drive unit
output side.
●
To avoid a malfunction of the servo motor, connect the wires to the correct phase terminals (U/V/W) of
the drive unit and the servo motor.
●
Connect the drive unit power outputs (U/V/W) to the servo motor power inputs (U/V/W) directly. Do not
connect a magnetic contactor and others between them. Otherwise, it may cause a malfunction.
●
The connection diagrams in this Instruction Manual are shown for sink interfaces, unless stated
otherwise.
●
Install the surge absorbing diode to the DC relay for control output signals in the converter unit and the
drive unit in the specified direction. Otherwise, the converter unit and the drive unit will malfunction
and will not output signals, disabling the emergency stop and other protective circuits.
●
When the wires are not tightened enough to the terminal block, the wires or terminal block may
generate heat because of the poor contact. Be sure to tighten the wires with specified torque.
●
Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the drive unit may cause a
malfunction.
●
To prevent an unexpected restart of the drive unit, configure a circuit to turn off EM2 or EM1 when the
main circuit power is turned off.
●
To prevent malfunction, avoid bundling the power lines (input/output) of the converter unit and the
signal cables together or running them in parallel to each other. Separate the power lines from the
signal cables.
