1.1. Checking the XtraDrive Series Products on Delivery

The following procedure is suggested to check XtraDrive series products upon delivery.

Use the following checklist when XtraDrive series products are delivered.

Initial Inspection Comments

Are the delivered products the ones that were ordered?

Check the model numbers marked on the nameplates of the servomotor and servo amplifier. (Refer to the descriptions of model numbers on following pages)

Does the servomotor shaft rotate smoothly?

The servomotor shaft is normal if it can be turned smoothly by hand. Servomotors with brakes, however, cannot be turned manually.

Is there any damage? Check the overall appearance, and

check for damage or scratches that may have occurred during shipping.

Are there any loose screws? Check screws for looseness using a

screwdriver.

If any of the above are faulty or incorrect, contact YET or an authorized distributor.

2.1. Servo Amplifiers

The XtraDrive servo amplifiers are base-mounted. Incorrect installation will cause problems. Follow the installation instructions below.

2.1.1. Storage Conditions

Store the servo amplifier within the following temperature range, as long as it is stored with the power cable disconnected.

-20 to 85°C

2.1.2. Installation Site

The following precautions apply to the installation site.

Situation Installation Precaution

Installation in a Control Panel

Design the control panel size, unit layout, and cooling method so the temperature around the servo amplifier does not exceed 55°C.

Installation Near a Heating Unit

Minimize heat radiated from the heating unit as well as any temperature rise caused by natural convection so the temperature around the servo amplifier does not exceed 55°C.

Installation Near a Source of Vibration

Install a vibration isolator beneath the servo amplifier to avoid subjecting it to vibration.

Installation at a Site Exposed to Corrosive Gas

Corrosive gas does not have an immediate effect on the servo amplifier, but will eventually cause electronic components and contactor-related devices to malfunction. Take appropriate action to avoid corrosive gas.

Other Situations

Do not install the servo amplifier in hot and humid locations or locations subject to excessive dust or iron powder in the air.

Page 23

XtraDrive User Manual Chapter 2: Installation

2-3

2.1.3. Orientation

Install the servo amplifier perpendicular to the wall as shown in the figure. The servo amplifier must be oriented this way because it is designed to be cooled by natural convection or by a cooling fan.

Secure the servo amplifier using the mounting holes. The number of holes varies (from two to four) with the frame size of the servo amplifier.

2.1.4. Installation

Follow the procedure below to install multiple servo amplifiers side by side in a control panel.

Page 24

XtraDrive User Manual Chapter 2: Installation

2-4

 Servo Amplifier Orientation

Install the servo amplifier perpendicular to the wall so the front panels’ connectors faces outward.

 Cooling

As shown in the figure above, allow sufficient space around each servo amplifier for cooling by cooling fans or natural convection.

 Side-by-side Installation

When installing servo amplifiers side by side as shown in the figure above, allow at least 0.39in (10mm) between and at least 1.97in (50mm) above and below each servo amplifier. Install cooling fans above the servo amplifiers to avoid excessive temperature rise and to maintain even temperature inside the control panel.

 Environmental Conditions in the Control Panel

• Ambient Temperature: 0 to 55°C

• Humidity: 90% RH or less

• Vibration: 0.5 G (4.9m/s

)

• Condensation and Freezing: None

3.3. Main Circuit Wiring

This section shows typical examples of main circuit wiring for XtraDrive Series servo products, functions of main circuit terminals, and the power ON sequence.

Observe the following precautions when wiring.

CAUTION

•

Do not bundle or run power and signal line s together in the same duct. Keep power and signal lines separated by at least 30cm (11.81 in).

Not doing so may cause a malfunction.

• Use twisted pair wires or multi-core shielded-pair wires for signal and encoder (PG)

feedback lines.

The maximum length is 3m (118.11 in) for reference input lines and is 20m (787.40 in) for PG feedback lines.

• Do not touch the power terminals for 5 minutes after turning power OFF because high

voltage may still remain in the servo amplifier.

Make sure the charge indicator is out first before starting an inspection.

•

Avoid frequently turning power ON and OFF. Do not turn power ON or OFF more than once per minute.

Since the servo amplifier has a capacitor in the power supply, a high charging current flows for 0.2s when power is turned ON. Frequently turning power ON and OFF causes main power devices like capacitors and fuses to deteriorate, resulting in unexpected problems.

4.2. Additional Setup Procedures in Trial Operation

For two equipment configurations, which are delineated in the subsequent sections, precautionary setup procedures must be followed before starting trial operation.

4.2.1. Servomotors with Brakes

Use a servomotor with a brake for vertical shaft applications or for the application of external force to the shaft to prevent rotation due to gravity or external force during a power loss.

The servo amplifier uses the brake interlock output (/BK) signal to control the holding brake operation when using servomotors with brakes.

5.1. Settings According to Device Characteristics

This section describes the procedure for setting parameters according to the dimensions and performance characteristics of the equipment used.

5.1.1. Switching Servomotor Rotation Direction

XtraDrive has a Reverse Rotation mode that reverses the direction of servomotor rotation without rewiring. Forward rotation in the standard setting is defined as counterclockwise as viewed from the load.

With the Reverse Rotation mode, the direction of servomotor rotation can be reversed without changing other parameters. Only the direction (+, −) of shaft motion is reversed.

Using the /P-CON Signal

 Input P-CON CN1-41

Proportional Control Reference

Speed Control, Position Control

The /P-CON input signal switches the Speed Control mode from PI (proportional-integral) to P (proportional) control.

Proportional control can be used in the following two ways:

• When an operation is performed by sending speed references from

the host controller to the servo amplifier, the host controller can selectively use the P control mode for particular conditions only. This method can prevent the occurrence of overshoot and also shorten settling time.

• If PI control mode is used when the speed reference has a reference

offset, the motor may rotate at a very slow speed and fail to stop even if 0 is specified as speed reference. In this case, use the P control mode to stop the motor.

5.2.2. Position Reference

The reference pulse, reference code, and clear inputs are used for the position reference. Since this signal can be used in different ways, set the optimal reference input for the system created.

 Reference by Pulse Input

Positioning is controlled by entering a reference pulse for a move.

Any of the following forms can be used for the position reference:

• Line-driver output

• +12V open-collector output

• +5V open-collector output

IMPORTANT

•

When using the servo amplifier phase C pulse signal to return to the machine origin, always turn the servomotor at least twice before starting the original return operation.

If the configuration of the mechanical system prevents turning the servomotor before the origin return operation, then perform the origin return operation at a servomotor speed of 600rpm or below. The phase C pulse signal may not be correctly applied if the servomotor turns faster than 600rpm.

5.2.5. Using the Electronic Gear Function

The electronic gear function enables the servomotor travel distance per input reference pulse to be set to any value. It allows the pulses generated by the host controller to be used for control without having to consider the equipment gear ratio or the number of encoder pulses.

Workpiece

Ball screw pitch: 6mm (0.24 in) No. of encoder pulses: 2048

To move a workpiece 10 mm (0.39 in): 1 revolution is 6 mm. Therefore, 10

6 = 1.6666 revolutions 2048 x 4 pulses is 1 revolution. Therefore,1.6666 x 2048 x 4 = 13653 pulses are input as reference. The equation must be calculated at the host controller.

Equipment conditions and reference units

must be defined for the electronic

gear function beforehand.

To move a workpiece 10 mm (0.39 in): Reference unit is 1

 Setting the Electronic Gear (for Reference Pulses)

Calculate the electronic gear ratio (B/A) using the following procedure, and set the values in parameters Pn202 and 203.

2. Determine the reference unit used.

A reference unit is the minimum position data unit used to move a load (minimum unit of reference from the host controller).

Reference unit : 0. 001 mm

Determine the reference unit according t o equipment spec ifications and posi ti oning ac curacy.

To move a t able in 0.001 mm unit s

Examples (in mm):

• Reference unit can be 0.1in or 0.01in or 0.01mm or 0.001mm,

etc. A reference unit of one pulse moves the load by one reference unit.

• When the reference unit is 1µm

If a reference of 50000 units is input, the load moves 50mm (1.97in) (50000 ⋅ 0.001mm = 50mm).

3. Determine the travel distance per load shaft revolution in reference units.
