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
Installation Near a Heating Unit
Installation Near a Source of Vibration
Design the control panel size, unit layout, and cooling method so the temperature around the servo amplifier does not exceed 55°C.
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.
Install a vibration isolator beneath the servo amplifier to avoid subjecting it to vibration.
Installation at a Site Exposed to Corrosive Gas
Other Situations
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.
Do not install the servo amplifier in hot and humid locations or locations subject to excessive dust or iron powder in the air.
2-2
XtraDrive User Manual Chapter 2: Installation

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.
2-3
XtraDrive User Manual Chapter 2: Installation
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.

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 lines 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 O N 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.

3.6. Examples of Standard Connections

The following diagrams show examples of standard servo amplifier connections by specifications and type of control.
Note for single-phase power supply specifications:
XtraDrive XD-08** have changed from three-phase specifications to single­phase. Main circuit connection terminals (L1, L2, L3) remained.
These devices have terminal B3 and internal regenerative resistor. Observe the following points.
1. Connect main power supply shown below to L1 and L3 terminals. Power supply is single-phase, 220 to 230 VAC +10% to –15%, 50/60Hz. If power supply of 187V (-15% of220V) or less is used, alarm A41 indicating voltage shortage, may occur when accelerating to max speed with max torque of motor.
2. Short-circuit B2 and B3 terminals using the internal regenerative resistor. If capacity of the regenerative resistor is insufficient, remove the lead between B2 and B3 terminals and connect an external regenerative resistor unit to B1 and B2 terminals.

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
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.

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).
To move a t able in 0.001 mm units
Reference unit : 0.001 mm
Determine the reference unit according t o equipment spec ifications and positioning ac curacy.
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.
