3.12 Grounding

WARNING

Ground the servo amplifier and servo motor securely.

To prevent an electric shock, always connect the protective earth (PE) terminal

(terminal marked

) of the servo amplifier with the protective earth (PE) of the

control box.

The servo amplifier switches the power transistor on-off to supply power to the servo motor. Depending on the

wiring and ground cable routing, the servo amplifier may be affected by the switching noise (due to di/dt and

dv/dt) of the transistor. To prevent such a fault, refer to the following diagram and always ground.

To conform to the EMC Directive, refer to the EMC Installation Guidelines (IB(NA)67310).

3.13 Control axis selection

POINT

The control axis number set to rotary axis setting switch (SW1) should be the

same as the one set to the servo system controller.

Use the rotary axis setting switch (SW1) to set the control axis number for the servo. If the same numbers are

set to different control axes in a single communication system, the system will not operate properly. The control

axes may be set independently of the SSCNET

cable connection sequence.

Set the test operation select switch to the "Up" position, when

performing the test operation mode by using MR Configurator.

Spare (Be sure to set to the "Down" position.)

4. STARTUP

WARNING

Do not operate the switches with wet hands. You may get an electric shock.

CAUTION

Before starting operation, check the parameters. Some machines may perform

unexpected operation.

Take safety measures, e.g. provide covers, to prevent accidental contact of hands

and parts (cables, etc.) with the servo amplifier heat sink, regenerative resistor,

servo motor, etc. since they may be hot while power is on or for some time after

power-off. Their temperatures may be high and you may get burnt or a parts may

damaged.

During operation, never touch the rotating parts of the servo motor. Doing so can

cause injury.

4.1 Switching power on for the first time

When switching power on for the first time, follow this section to make a startup.

4.1.1 Startup procedure

Wiring check

Surrounding environment check

Axis No. settings

Parameter setting

Test operation of servo motor

alone in test operation mode

Test operation of servo motor

alone by commands

Test operation with servo motor

and machine connected

Gain adjustment

Actual operation

Stop

Check whether the servo amplifier and servo motor are wired correctly using

visual inspection, DO forced output function (section 4.5.1), etc. (Refer to

section 4.1.2.)

Check the surrounding environment of the servo amplifier and servo motor.

(Refer to section 4.1.3.)

Confirm that the axis No. settings for rotary axis setting switch (SW1) and

servo system controller are consistent. (Refer to section 3.12)

Set the parameters as necessary, such as the used control mode and

regenerative option selection. (Refer to chapter 5)

For the test operation, with the servo motor disconnected from the machine

and operated at the speed as low as possible, check whether the servo moto

rotates correctly. (Refer to sections 4.5)

For the test operation with the servo motor disconnected from the machine

and operated at the speed as low as possible, give commands to the servo

amplifier and check whether the servo motor rotates correctly.

Connect the servo motor with the machine, give operation commands from the

host command device, and check machine motions.

Make gain adjustment to optimize the machine motions. (Refer to chapter 6.)

Stop giving commands and stop operation.
