For Safe Operations

1. Prevention of electric shocks

DANGER

Never open the front case or terminal covers of the servo amplifier while the power is ON or the

unit is running, as this may lead to electric shocks.

Never run the unit with the front case or terminal cover of the servo amplifier removed. The high

voltage terminal and charged sections will be exposed and may lead to electric shocks.

Never open the front case or terminal cover of the servo amplifier at times other than wiring work

or periodic inspections even if the power is OFF. The insides of the position board and servo amplifier are charged and may lead to electric shocks.

Completely turn off the externally supplied power used in the system before mounting or

removing the position board, performing wiring work, or inspections. Failing to do so may lead to electric shocks.

When performing wiring work or inspections, turn the power OFF, wait at least ten minutes, and

then check the voltage with a tester, etc. Failing to do so may lead to electric shocks.

Be sure to ground the controller incorporating the position board, servo amplifier and servo

motor. (Ground resistance : 100 The wiring work and inspections must be done by a qualified technician. Wire the units after installing the position board, servo amplifier and servo motor. Failing to do so

may lead to electric shocks or damage. Never operate the switches with wet hands, as this may lead to electric shocks. Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this

may lead to electric shocks. Do not touch the position board, servo amplifier or servo motor terminal blocks while the power is

ON, as this may lead to electric shocks. Do not touch the built-in power supply, built-in grounding or signal wires of the position board

and servo amplifier, as this may lead to electric shocks.

2. For fire prevention

or less) Do not ground commonly with other devices.

CAUTION

Install the position board, servo amplifier, servo motor and regenerative resistor on incombustible.

Installing them directly or close to combustibles will lead to fire. If a fault occurs in the position board or servo amplifier, shut the power OFF at the servo

amplifier’s power source. If a large current continues to flow, fire may occur. When using a regenerative resistor, shut the power OFF with an error signal. The regenerative

resistor may abnormally overheat due to a fault in the regenerative transistor, etc., and may lead

to fire. Always take heat measures such as flame proofing for the inside of the control panel where the

servo amplifier or regenerative resistor is installed and for the wires used. Failing to do so may

lead to fire. Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this

may lead to fire.

A - 2

3. For injury prevention

CAUTION

Do not apply a voltage other than that specified in this manual and the instruction manual of the

product you are using on any terminal.

Doing so may lead to destruction or damage. Do not mistake the terminal connections, as this may lead to destruction or damage. Do not mistake the polarity ( + / - ), as this may lead to destruction or damage. Do not touch the heat radiating fins of position board or servo amplifier, regenerative resistor and

servo motor, etc., while the power is ON and for a short time after the power is turned OFF. In this

timing, these parts become very hot and may lead to burns. Always turn the power OFF before touching the servo motor shaft or coupled machines, as these

parts may lead to injuries. Do not go near the machine during test operations or during operations such as teaching.

Doing so may lead to injuries.

4. Various precautions

Strictly observe the following precautions.

Mistaken handling of the unit may lead to faults, injuries or electric shocks.

(1) System structure

CAUTION

Always install a leakage breaker on the controller incorporating the position board and servo

amplifier power source.

If installation of an electromagnetic contactor for power shut off during an error, etc., is specified in

the instruction manual for the servo amplifier, etc., always install the electromagnetic contactor.

Install the emergency stop circuit externally so that the operation can be stopped immediately and

the power shut off.

Use the position board, servo amplifier, servo motor and regenerative resistor with the correct

combinations listed in the instruction manual. Other combinations may lead to fire or faults.

If safety standards (ex., robot safety rules, etc.,) apply to the system using the position board,

servo amplifier and servo motor, make sure that the safety standards are satisfied.

Construct a safety circuit externally of the position board or servo amplifier if the abnormal

operation of the position board or servo amplifier differ from the safety directive operation in the system.

In systems where coasting of the servo motor will be a problem during the forced stop, emergency

stop, servo OFF or power supply OFF, use dynamic brakes. Make sure that the system considers the coasting amount even when using dynamic brakes. In systems where perpendicular shaft dropping may be a problem during the forced stop,

emergency stop, servo OFF or power supply OFF, use both dynamic brakes and electromagnetic

brakes.

A - 3

CAUTION

The dynamic brakes must be used only on errors that cause the forced stop, emergency stop, or

servo OFF. These brakes must not be used for normal braking.

The brakes (electromagnetic brakes) assembled into the servo motor are for holding applications,

and must not be used for normal braking.

The system must have a mechanical allowance so that the machine itself can stop even if the

stroke limits switch is passed through at the max. speed. Use wires and cables that have a wire diameter, heat resistance and bending resistance

compatible with the system. Use wires and cables within the length of the range described in the instruction manual. The ratings and characteristics of the parts (other than position board, servo amplifier and servo

motor) used in a system must be compatible with the position board, servo amplifier and servo

motor. Install a cover on the shaft so that the rotary parts of the servo motor are not touched during

operation. There may be some cases where holding by the electromagnetic brakes is not possible due to the

life or mechanical structure (when the ball screw and servomotor are connected with a timing belt,

etc.). Install a stopping device to ensure safety on the machine side.

(2) Parameter settings and programming

CAUTION

Set the parameter values to those that are compatible with the position board, servo amplifier,

servo motor and regenerative resistor model and the system application. The protective functions may not function if the settings are incorrect.

The regenerative resistor model and capacity parameters must be set to values that conform to

the operation mode and servo amplifier. The protective functions may not function if the settings

are incorrect. Set the mechanical brake output and dynamic brake output validity parameters to values that are

compatible with the system application. The protective functions may not function if the settings

are incorrect. Set the stroke limit input validity parameter to a value that is compatible with the system

application. The protective functions may not function if the setting is incorrect. Set the servo motor encoder type (increment, absolute position type, etc.) parameter to a value

that is compatible with the system application. The protective functions may not function if the

setting is incorrect. Set the servo motor capacity and type (standard, low-inertia, flat, etc.) parameter to values that

are compatible with the system application. The protective functions may not function if the

settings are incorrect. Set the servo amplifier capacity and type parameters to values that are compatible with the

system application. The protective functions may not function if the settings are incorrect. Use the program commands for the program with the conditions specified in the instruction

manual.

(8) Maintenance, inspection and part replacement

CAUTION

Perform the daily and periodic inspections according to the instruction manual.

Perform maintenance and inspection after backing up the program and parameters for the

position board and servo amplifier. Do not place fingers or hands in the clearance when opening or closing any opening. Periodically replace consumable parts such as batteries according to the instruction manual. Do not touch the lead sections such as ICs or the connector contacts.

Before touching the position board, always touch grounded metal, etc. to discharge static

electricity from human body. Failure to do so may cause the position board to fail or malfunction.

Do not directly touch the position board's conductive parts and electronic components.

Touching them could cause an operation failure or give damage to the position board. Do not place the position board or servo amplifier on metal that may cause a power leakage or

wood, plastic or vinyl that may cause static electricity buildup. Do not perform a megger test (insulation resistance measurement) during inspection. When replacing the position board or servo amplifier, always set the new position board

settings correctly. When the position board or absolute value motor has been replaced, carry out a home position

return operation from the user program. Failing to do so may cause position displacement. After maintenance and inspections are completed, confirm that the position detection of the

absolute position detector function is correct.

Do not drop or impact the battery installed to the module.

Doing so may damage the battery, causing battery liquid to leak in the battery. Do not use the

dropped or impacted battery, but dispose of it. Do not short circuit, charge, overheat, incinerate or disassemble the batteries. The electrolytic capacitor will generate gas during a fault, so do not place your face near the

position board or servo amplifier. The electrolytic capacitor and fan will deteriorate. Periodically replace these to prevent secondary

damage from faults. Replacements can be made by our sales representative. Lock the control panel and prevent access to those who are not certified to handle or install

electric equipment. Do not burn or break a position board and servo amplifier. Doing so may cause a toxic gas.

The MR-MC210 has one SSCNET control channel (hereinafter: CH) and one SSCNET line (hereinafter: line), and can control positioning for up to 20 axes. The MR-MC211 has one SSCNET control channel and two SSCNET lines, and can control positioning for up to 32 axes (up to 20 axes per line). By reading and writing the dual port memory mapped to the memory space of the PCI bus, the host controller can command position board to start operation, and get servo amplifier status. The host controller can also receive position pass and positioning complete interruptions via PCI bus. The position board is equipped with standard mode and interface mode for positioning control. The positioning control mode that corresponds with the application can be selected by parameter. The mode cannot be changed during SSCNET communication (while system is running). Positioning in standard mode is performed using a point table mapped on the dual port memory of the position board. Arbitrary positioning is possible by writing data to this point table from the host controller. Also, startup of JOG operation and home position return, etc. as well as parameters changing and monitoring are possible through accessing this dual port memory on the position board from the host controller. Interface mode is a sequential positioning command method that uses a user program on the host controller. The user program controls the servo amplifier with an arbitrary acceleration/deceleration pattern by writing the position command to the position command buffer of the position board every communication cycle (control cycle). Some functions from standard mode cannot be used, or are restricted when in interface mode.

1.2 Features

The position board has the following features.

(1) Structuring of SSCNET

The position board can be directly connected to the Mitsubishi servo amplifiers of MR-J4-B series using SSCNET (a) By connecting the position board and servo amplifier and servo amplifiers with a high speed

synchronous network by SSCNET between the position board and servo amplifier, or servo amplifier and servo amplifier for the SSCNET cable on the same bus is 100(328.08)[m(ft.)]. This increases flexibility at system design.

(b) By using SSCNET

servo amplifiers and such is reduced.

from the servo amplifier using the SSCNET communication.

(d) The current feedback position and error description contained in the servo can be checked by the dual

port memory of the position board.

(e) Communication between MR Configurator2 and the servo amplifiers is possible via the position board

USB.

(2) Programming in C programming language with the API library

Positioning control for the servo in C programming language is enabled with the API library included with the Position Board Utility2 (MRZJW3-MC2-UTL).

(3) Supports event-driven programming

The host controller is notified by interrupt via PCI bus when the conditions for an interrupt such as passing through a preset point or positioning complete are met. The user program can create event-driven programs according to interrupt factors.

(4) High-speed operation starting time

High-speed operation starting time within the control cycle (0.22ms fastest) is achieved for the maximum number of synchronous startup axes or less.

(5) Wide variety of positioning control functions

The main functions (such as home position return control, standard mode, and interface mode (sequential positioning command method)) which are required for any positioning system and the sub functions which limit and add functions to those controls are supported. (a) Enhanced home position return control

Additional features of home position return control Ten home position return methods are provided: dog cradle method, dog method, data set method, continuous operation to torque method, limit switch combined method, scale home position signal detection method, limit switch front end method, dog front end method, Z-phase detection method, and scale home position signal detection method 2. Select an applicable method according to the system.

(b) Wide variety of control methods

Positioning control methods such as positioning control are provided.

1) Independent control of each axis Position control can be performed independently for each axis at any given timing.

2) Interpolation control Interpolation controls using multiple axes can be performed. (2-axis to 4-axis linear interpolation control)

3) Tandem drive Tandem drive for 2 axes can be performed. In scale home position signal detection method and scale home position signal detection method 2, the deviation between the 2 axes at home position return can be compensated.

4) Interface mode The user program controls the servo amplifier with an arbitrary acceleration/deceleration pattern that is not supported in standard mode by writing the position command to the position command buffer of

(6) Supports other axes start function

(7) High maintainability

the position board every communication cycle (control cycle).

Multiple positioning data can be processed continuously within one operation start.

(d) Acceleration/deceleration processing

Four acceleration/deceleration processing methods are provided: Linear acceleration/deceleration, S-curve acceleration/deceleration, start up speed, and smoothing filter. The acceleration/deceleration curve can be selected according to the machine characteristic.

With the other axes start function, the position board can determine the conditions and automatically start other axes, and turn on/off output signals. The position board does not go through user program processing so there are no delays or dispersions. This also lessens the load on the user program.

Maintainability is enhanced in the position board. (a) Data retention without battery

Parameter data can be stored in the flash ROM inside the position board. This feature allows the retaining of data without a battery.

(b) Alarm collection function

The alarm details when an alarm occurs are automatically stored in the flash ROM inside the position board. Storing the alarm information allows the user to check the alarm from the user program or test tool even after the position board is powered off or reset.
