Safety Precautions

■ Do not connect the servomotor directly to the local electrical network.

Failure to observe this may result in damage to servomotor.

■ Do not plug or unplug connectors from servo drive when power is on.

Failure to observe this may result in damage to servo drive and servomotor.

■Please note that even after power is removed, residual voltage still remains in the capacitor inside the servo drive. If

inspection is to be performed after power is removed, please wait 5 minutes to avoid risk of electrical shock.

■ Keep servo drives and other devices separated by at least 10mm.

The servo drive generates heat. Install the servo drive so that it can radiate heat freely. When installing servo drives

with other devices in a control panel, provide at least 10mm space between them and 50mm space above and below

them. Please install servo drives in an environment free from condensation, vibration and shock.

■ Perform noise reduction and grounding properly.

Please comply with the following instructions to avoid noise generated by signal lines.

1. Separate high-voltage cables from low-voltage cables.

2. Use cables as short as possible.

3. Single point grounding is required for the servomotor and servo drive (grounding resistance 100Ω or below).

4. Never use a line filter for the power supply in the circuit.

■ Conduct a voltage resistance test for the servo drive under the following conditions:

1. Input voltage: AC 1500Vrms, 1 minute

2. Braking current: 100mA

3. Frequency:50/60Hz

4. Voltage applied point: Between L1, L2,L3 terminals and frame ground.

■ Use a fast-response type ground-fault interrupter.

For a ground-fault interrupter, always use a fast-response type or one designed for PWM inverters. Do not use a

time-delay type.

■ Do not make any extreme adjustments or setting changes of parameters.

Failure to observe this caution may result in injury or damage to the product due to unstable operation.

■ The servomotor cannot be operated by turning the power on and off.

Frequently turning the power ON and OFF causes the internal circuit elements to deteriorate, resulting in unexpected

problems. Always start or stop the servomotor by using reference pulses.

2. There is no brake mounted on the EMG-□□□DA□□ servomotor.

Check Items Comments

Are the delivered products the ones that

were ordered?

Check the model numbers marked on the nameplate on the

servomotor and servo drive.

Is there any damage?

Check the overall appearance, and check for damage or scratches

that may have occurred during shipping.

Does the servomotor shaft rotate smoothly?

If the servomotor shaft can be easily rotated by hand, then the motor

is working normally. However, if a brake is installed on the

servomotor, then it cannot be turned by hand.

Installation

2.1 Servomotor

Servomotor can be installed either horizontally or vertically. However, if the servomotor is installed incorrectly, the

service life of the servomotor will be shortened or unexpected problems may occur.

Please observe the installation instructions described below to install the servomotor correctly.

Before installation:

Anticorrosive paint is coated on the edge of the servomotor shaft. Clean off the anticorrosive paint thoroughly using

a cloth moistened with thinner.

Avoid getting thinner on other parts of the servomotor when cleaning the shaft.

2.1.1 Storage

When the servomotor is not being used, store it in an area with a temperature between -25℃ and 60℃ with the power

cable disconnected.

2.1.2 Installation Sites

The servomotor is designed for indoor use. Install the servomotor in an environment which meets the following

conditions.

z Free from corrosive and explosive gases.

z Well-ventilated and free from dust and moisture.

z Ambient temperature from 0 to 40℃.

z Relative humidity from 26% to 80%( non-condensing).

z Facilitates inspection and cleaning.

ProNet Series AC Servo User's Manual

- 22 -

2.1.3 Installation Alignment

Align the shaft of the servomotor with that of the machinery shaft to be controlled. Then connect the two shafts with an

elastic coupling.

Install the servomotor so that alignment accurancy falls within the range shown below.

Measure this distance at four different positions in the circumference. The difference between the maximum and

minimum measurements must be 0.03mm or less.(Turn together with couplings.)

Note:

·If the alignment accurancy is incorrect , vibration will occur, resulting in damage to the bearings.

·Mechanical shock to the shaft end is forbidden, otherwise it may result in damage to the encoder of the servomotor.

2.1.4 Installation Orientation

Servomotor can be installed ethier horizontally or vertically.

2.1.5 Handling Oil and Water

If the servomotor is used in a location that is subject to water or oil drops, make sure of the servomotor protective

specification. If the servomotor is required to meet the protective specification to the through shaft section by default,

use a servomotor with an oil seal.

Through shaft section:

It refers to the gap where the shaft protrudes from the end of the servomotor.

Through Shaft Section

2.1.6 Cable Tension

When connecting the cables, the bending radius should not be too small, do not bend or apply tension to cables.
Since the conductor of a signal cable is very thin (0.2 mm or 0.3 mm), handle it with adequate care.

2.1.7 Install to the Client

When the servo motor is mounted to the client, please firmly secure the servo motor by the screws with backing ring

as shown in the figure.

2.2 Servo Drive

ProNet series servo drive is a base-mounted type. Incorrect installation will cause problems. Always observe the
installation instructions described below.

2.2.1 Storage

When the servomotor is not being used, store it in an area with a temperature between -25℃ and 55℃ with the
power cable disconnected.

2.2.2 Installation Sites

Notes on installation are shown below.

Situation Notes on installation

When installed in a control

panel

Design the control panel size, unit layout, and cooling method so that the temperature

around the periphery of the servo drive does not exceed 55℃.

When installed near a

heating unit

Suppress radiation heat from the heating unit and a temperature rise caused by

convection so that the temperature around the periphery of the servo drive does not

exceed 55℃.

When installed near a

source of vibration

Install a vibration isolator underneath the servo drive to prevent it from receiving vibration.

When installed in a location

subject to corrosive gases

Take appropriate action to prevent corrosive gases. Corrosive gases do not immediately

affect the servo drive, but will eventually cause contactor-related devices to malfunction.

Others

Avoid installation in a hot and humid site or where excessive dust or iron powder is

present in the air.

ProNet Series AC Servo User's Manual

2.2.3 Installation Orientation

Install the servo drive perpendicular to the wall as shown in the figure. The servo drive must be oriented this way

because it is designed to be cooled by natural convection or a cooling fan if required. Firmly secure the servo drive

through two mounting holes.

2.2.4 Installation Method

When installing multiple servo drives side by side in a control panel, observe the following installation method.

Colling Fan

Colling Fan

■Installation Orientation

Install servo drive perpendicular to the wall so that the front panel (containing connectors) faces outward.

■Cooling

Provide sufficient space around each servo drive to allow cooling by natural convection or fans.

■Installing side by side

When installing servo drives side by side, provide at least 10mm space between each individual servo drive and at

least 50mm space above and below each one as well as shown in the figure above. Ensure the temperature inside the

control panel is evenly distributed, and prevent the temperature around each servo drive from increasing excessively.

Cooling Fan Cooling Fan

Install cooling fans above the servo drives if necessary.

■Working conditions

2.Humidity：5%~95%RH

3.Vibration：4.9m/s

Wiring

3.1 Main Circuit Wiring

Please observe the following instructions while wiring the main circuit.

· Do not bundle or run power and signal lines together in the same duct. Keep power and signal lines

separated by at least 300 mm.

· Use twisted-pair shielded wires or multi-core twisted-pair shielded wires for signal and encoder feedback

lines.

· The maximum length is 3 m for reference input lines and 20 m for encoder feedback lines.

· Do not touch the power terminals for 5 minutes after turning power OFF because high voltage may still

remain in the servo drive.
