2.1. Main circuit and peripheral device connection
This part explains the peripheral device and main circuit wiring. Keep the following danger and
caution details during wiring.
Danger
!

Do not open the surface cover when connecting the power or during operation. It can cause
electric shock.

Do not operate the drive when the surface cover is removed.
It can cause electric shock because the high voltage terminal and charge part are exposed.

Even when the power is turned off, do not remove the surface cover unless it is for wiring or
periodic check.
It can cause electric shock because the inside of the servo drive is charged.

Execute the wiring work and check more than 10 minutes after the power has been
disconnected and checked of the voltage with tester etc.

Ground the grounding terminal of the drive and motor both to the drive side and ground at
once in the closest point.
To protect electric shock and mis-operation, use at least class-3 ground (100

max.).

The wiring work and checking work must be executed by specialized technician.

The wiring must be done after the main unit is installed. It can cause electric shock or injury.

Do not operate the key with wet hands. It can cause electric shock or injury.

Make sure you do not damage the wire, apply excessive stress on the wire, put heavy object
on top of the wire or have the wire pressed again an object. It can cause electric shock or
injury.
Caution
!

Use wiring that complies with the standard. Otherwise, the servo motor may not operate.

Do not install power condenser, surge absorber or radio noise filter on the output side of the
servo drive.

Correctly connect the output side (Terminal U,V,W,FG), or the motor can operate abnormally.

When attaching the DC relay for control output signal on the control output signal part, be
careful of the diode direction for surge absorption. The signal may not be outputted due to
problems and the protection circuit will not operate during emergency stop. For diode
direction, refer to the user manual.
