x Changes to Zone Function

Applicable application versions: V0016 and later Among the zone signal settings, those that result in “Zone setting+ < Zone setting-” are now effective. V0015 and earlier: “Zone setting+ d Zone setting-” o A zone signal is not output. V0016 and later: “Zone setting+ = Zone setting-” o This is the only condition in which a zone signal is not output. Accordingly, you can now output a zone signal even when a rotary actuator is operated over the 0q position in the index mode. An example is given below.

[Rotary actuator in index mode]

Zone signal ON range

Set value Set value

Zone setting+: 70q Zone setting+: 315q Zone setting-: 315q Zone setting-: 70q

CAUTION

1. Use Environment

PCON controllers can be used in an environment of pollution degree 2 or equivalent.

2. PC Software and Teaching Pendant Models

New functions have been added to the entire PCON controller series. To support these new features, the communication protocol has been changed to the general Modbus (Modbus-compliant) mode. As a result, the existing PC software programs and teaching pendants compatible with RCP2 controllers can no longer be used. If you are using this controller, use a compatible PC software program and/or teaching pendant selected from the following models.

skrameRrebmunledoM

PC software RCM-101-***

Teaching pendant CON-T, RCM-T

Simple teaching pendant RCM-E

Data setting unit RCM-P

Touch panel display RCM-PM-01 Not compatible with RCP2 controllers

All are compatible with existing RCP2

controllers

3. Recommendation for Backing up Latest Data

This product uses nonvolatile memory to store the position table and parameters. Normally the memory will retain the stored data even after the power is disconnected. However, the data may be lost if the nonvolatile memory becomes faulty. We strongly recommend that the latest position table and parameter data be backed up so that the data can be restored quickly when the controller must be replaced for a given reason. The data can be backed up using the following methods: [1] Save to a CD or FD from the PC software. [2] Create a position table sheet or parameter sheet and keep a written record of backup.

CAUTION

4. Initial Parameter Settings at Startup

After applying power, at least the three parameters specified below must be set in accordance with the specific application. Inappropriate settings of these parameters will prevent the controller from operating properly, so exercise due caution. For details on how to set the parameters, refer to “Parameter Settings” in the operation manual for the PC or teaching pendant.

[1] Selecting the PIO pattern

This controller provides six PIO pattern types to meet the needs of various applications. To select a desired type, set a corresponding value from 0 to 5 in parameter No. 25 (PIO pattern selection). The factory setting is “0 [Standard type].”

Parameter No.

25 setting

0 Standard type

A basic type supporting 64 positioning points and two zone outputs. * How to set zone boundaries within which to output a zone signal: Zone boundaries are set using parameter Nos. 1 and 2 for one zone output, and in the position table for another zone output.

1 Teaching type

In this type, 64 positioning points and one zone output (boundaries are set in the position table) are supported. In addition to the normal positioning mode, the user can also select the teaching mode in which the actuator can be jogged via commands from a PLC and the current actuator position can be written to a specified position. (Note 1) Jog commands from a PLC are also accepted in the positioning mode. (Note 2) Positions can be rewritten by approximately 100,000 times.

2 256-point positioning type

The number of positioning points is increased to 256, so only one zone output is available (boundaries are set in the position table).

3 512-point positioning type

The number of positioning points is increased to 512, so no zone output is available.

4 7-point type

The number of positioning points is limited to seven to offer separate direct command inputs and position complete outputs for respective positions. PLC ladder sequence circuits can be designed easily.

Feature of PIO pattern

5 3-point type

Use of the controller as an air cylinder is assumed in this type. Position complete output signals function differently in this type, compared to the 7point type. Specifically, the signal functions not only to “indicate position complete,” but also to “detect a position” in the same manner as auto-switches of an air cylinder.

CAUTION

[2] Enabling/disabling the servo ON input signal (SON)

The servo ON input signal has been added to allow for servo ON/OFF control on the PLC side. Depending on the needs, therefore, the user must enable/disable this signal.

To select a desired setting, set “0” or “1” in parameter No. 21 (Servo ON input disable selection).

Enable (use) 0

Disable (do not use) 1

The factory setting is “0 [Enable].”

[3] Enabling/disabling the pause signal (*STP)

The pause signal uses the contact b logic to provide a failsafe function. Therefore, this signal must remain ON in normal conditions of use. Since there are applications where this signal is not used, a parameter is provided to disable the pause signal so it doesn’ t have to be turned ON.

To select a desired setting, set “0” or “1” in parameter No. 15 (Pause input disable selection).

Enable (use) 0

Disable (do not use) 1

The factory setting is “0 [Enable].”

5. Using a Rotary Actuator in Multi-rotation Specification

Rotary actuators of multi-rotation specification models let you select multi-rotation operation or limited-rotation operation using a parameter.

5.1 Notes Pay attention to the setting of the PIO pattern parameter for the controllers specified below. Each controller does not support relative coordination specification in the PIO pattern specified.

[1] PCON-C/CG: PIO pattern = 5 (User parameter No. 25) [2] PCON-CY: PIO pattern = 0 (User parameter No. 25)

Description

2 Transportation Ɣ When carrying a heavy object, do the work with two or more persons or

utilize equipment such as crane.

Ɣ When the work is carried out with 2 or more persons, make it clear who is

to be the leader and who to be the follower(s) and communicate well with each other to ensure the safety of the workers.

Ɣ When in transportation, consider well about the positions to hold, weight

and weight balance and pay special attention to the carried object so it would not get hit or dropped.

Ɣ Transport it using an appropriate transportation measure.

The actuators available for transportation with a crane have eyebolts attached or there are tapped holes to attach bolts. Follow the instructions in the operation manual for each model.

Ɣ Do not step or sit on the package. Ɣ Do not put any heavy thing that can deform the package, on it. Ɣ When using a crane capable of 1t or more of weight, have an operator

who has qualifications for crane operation and sling work.

Ɣ When using a crane or equivalent equipments, make sure not to hang a

load that weighs more than the equipment’s capability limit.

Ɣ Use a hook that is suitable for the load. Consider the safety factor of the

hook in such factors as shear strength.

Ɣ Do not get on the load that is hung on a crane. Ɣ Do not leave a load hung up with a crane. Ɣ Do not stand under the load that is hung up with a crane.

1. Overview

1.1 Introduction

This product is a dedicated RCP2 / RCP3 actuator controller that provides the same functions of the RCP2 controller as well as a set of new functions designed to achieve greater convenience and safety. The product also provides a power-saving function in response to growing energy-saving needs. The key features and functions are listed below.

z More positioning points

The standard type supports up to 64 points, while the extended types can handle up to 512 points. Availability of more positioning points is ideal for production lines where many types of products are produced in small volumes.

z Setting of zone output boundaries for each position in the position table

Before, zone output boundaries were set by parameters and therefore fixed. To add flexibility, new fields have been added to the position table so that different boundaries can be set for each position. This feature is useful in preventing contact with surrounding equipment and reducing the tact time, among others.

z Separate acceleration/deceleration settings

Acceleration and deceleration are now set in separate fields of the position table. Depending on the material or shape of the load, it is desirable to reduce shock and vibration when the actuator stops. Since acceleration and deceleration can be set differently, only the deceleration value can be reduced to make the deceleration curve more gradual.

z Limitation of feed speed in test operation and adjustment

The feed speed to be used in test operation and adjustment can be limited for added safety.

z Power-saving measures

In general, pulse motors consume more holding current in standstill state than AC servo motors. This product provides a power-saving means to support situations where the actuator must stand by for a long period.

1. Overview

When actually starting up your system or if you have encountered any problem, also refer to the operation manuals for the actuator, teaching pendant, PC software and other components used with the system, in addition to this manual.

This manual does not cover all possible operations other than normal operations, or unexpected events such as complex signal changes resulting from use of critical timings. Accordingly, you should consider items not specifically explained in this manual as “prohibited.”

Turn on the power and check for alarms

Supply the 24-V power after confirming that the emergency stop circuit is not actuated. If the monitor LED [SV/ALM] on the front face of the controller illuminates for two seconds and then turns off, the controller is functioning properly. If [SV/ALM] illuminates in red, it means an alarm has generated. Connect a PC or teaching pendant to check the nature of the alarm, and remove the cause by referring to Chapter 10, “Troubleshooting.”

Set the PIO pattern/safety speed

Set the mode selector switch on the front face of the controller to the “MANU” side. On the PC screen or teaching pendant, set the MANU operating mode to [Teaching mode: Enable safety speed/Inhibit PIOs]. In this condition, set appropriate values in parameter No. 25 (PIO pattern selection) and parameter No. 35 (Safety speed). * The factory-set PIO pattern and safety speed are “standard type” and “100 mm/s or less,” respectively. o

or equivalent.

3. Installation and Noise Elimination

3.2 Power Supply

The power supply specification is 24 VDC r 10%. (Supply current: 2 A max.: C/CG, 6 A: CF)

3.3 Noise Elimination and Grounding

This section explains how to eliminate noise in the use of the controller.

(1) Wiring and power supply

[1] Provide a dedicated class D grounding using a wire with a size of 2.0 to 5.5 mm2or larger.

Controller

Use a cable of a maximum possible size and keep the wiring length at a minimum.

Metal frame

Class D grounding Good Avoid this grounding method.

3. Installation and Noise Elimination

[2] Precautions regarding wiring method

Use a twisted cable for connection to the 24-VDC external power supply. Separate the controller cables from high-power lines such as a cable connecting to a power circuit. (Do not bundle together the controller cables with high-power lines or place them in the same cable duct.) When extending the supplied motor cable or encoder cable, consult IAI’s Technical Support.

(2) Noise sources and elimination

Among the numerous noise sources, solenoid valves, magnet switches and relays are of particular concern when building a system. Noise from these sources can be eliminated by implementing the measures specified below.

Other

equipment

Controller

Other

equipment

[1] AC solenoid valves, magnet switches and relays

Measure: Install a surge absorber in parallel with the coil.

Å Point

Install a surge absorber to each coil over a minimum wiring length. Installing a surge absorber to the terminal block or other part will be less effective because of a longer distance from the coil.

3. Installation and Noise Elimination

[2] DC solenoid valves, magnet switches and relays

Measure: Install a diode in parallel with the coil. Determine the diode capacity in accordance with the load

capacity.

In a DC circuit, connecting a diode in reverse polarity will damage the diode, internal parts of the controller and/or DC power supply, so exercise due caution.

3.4 Heat Radiation and Installation

Design the control panel size, controller layout and cooling method in such a way that the temperature around the controller will not exceed 40qC.

Install the controller vertically on a wall, as shown below. Since cooling is provided by way of natural convection, always observe this installation direction and provide a minimum clearance of 50 mm above and below the controller to ensure sufficient natural airflows.

When installing multiple controllers side by side, providing a ventilation fan or fans above the controllers will help maintain a uniform temperature around the controllers.

Keep the front panel of the controller away from the wall (enclosure) by at least 95 mm.

Fan

Regardless of whether your system consists of a single controller or multiple controllers, provide sufficient clearances around each controller so that it can be installed/removed easily.

To prevent confusion during wiring, the NPN and PNP specifications use the same power line configuration. Accordingly, there is no need to reverse the power signal assignments for a PNP controller.

5.2 PIO Patterns and Signal Assignments

Parameter No.

25 setting

Feature of PIO pattern

Positioning mode (Standard type) A basic type supporting 64 positioning points and two zone outputs. * How to set zone boundaries within which to output a zone signal: Zone boundaries are set using parameter Nos. 1 and 2 for one zone output, and in the position table for another zone output.

Teaching mode (Teaching type) In this type, 64 positioning points and one zone output (boundaries are set in the position table) are supported. In addition to the normal positioning mode, the user can also select the teaching mode in which the actuator can be jogged via I/Os and the current actuator position can be written to a specified position. (Note) Positions can be rewritten by approximately 100,000 times.

256-point mode (256-point positioning type) The number of positioning points is increased to 256, so only one zone output is available (boundaries are set in the position table).

512-point mod (512-point positioning) The number of positioning points is increased to 512, so no zone output is available.

Solenoid valve mode 1 (7-point type) The number of positioning points is limited to seven to offer separate direct command inputs and movement complete outputs. PLC ladder sequence circuits can be designed easily.

Solenoid valve mode 2 (3-point type) Use of the controller as an air cylinder is assumed in this type. Movement complete output signals function differently in this type, compared to the 7point type. Specifically, the signal functions not only to “indicate movement complete,” but also to “detect a position” in the same manner as auto-switches of an air cylinder. Push & hold operation cannot be performed.

(Note) For “Zone” and “Position zone,” different methods are used to set boundaries defining the range within

which the zone signal will turn ON. “Zone” is set by parameter Nos. 1 and 2, and thus its setting will become effective after home return is completed. “Position zone” is set in the “Zone+” and “Zone-“ fields for each position number in the position table, and thus its setting will become effective after a movement command is input.

5.2.1 Explanation of Signal Names

The following explains the signal names, and gives a function overview of each signal. In the explanation of operation timings provided in a later section, each signal is referenced by its selfexplanatory name for clarity. If necessary, however, such as when marker tubes are inserted as a termination of the flat cable, use the signal abbreviations.

Function overview

The target position number is input. A command position number must be specified by 6 ms before the start signal (CSTR) turns ON.

This signal is used on an actuator equipped with a brake to forcibly release the brake. This signal switches the operating mode between AUTO and MANU.

Home return operation is started at a rise edge of this signal. ON: Actuator can be moved, OFF: Actuator decelerates to a stop The actuator will start moving at a rise edge of this signal. An alarm is reset at a rise edge of this signal. The servo remains ON while this signal is ON.

The servo remains OFF while this signal is OFF.

The relevant position number is output when positioning has completed. The signal will turn OFF when the next start signal is received. It is used by the PLC to check if the commanded position has definitively been reached, and also to provide a position interlock, etc.

This signal will remain ON while the actuator is moving, and OFF while the actuator is standing still. It is used to determine whether the actuator is moving or paused. This signal becomes effective after home return. It will turn ON when the current actuator position enters the range set by the parameters and remain ON until the actuator exits the range. This signal becomes effective after a position movement command is input. It will turn ON when the current actuator position enters the range specified in the position table and remain ON until the actuator exits the range. This signal will remain OFF during the AUTO mode, and ON during the MANU mode.

This signal is OFF immediately after the power is input, and turns ON when home return has completed.

This signal turns ON when the target position was reached and the actuator has entered the specified in-position range. It is used to determine whether positioning has completed. This signal is always output once the servo is turned ON and the controller is ready to operate. When this signal is OFF, it means that an emergency stop is being actuated. This signal remains ON in normal conditions of use and turns OFF when an alarm generates. This signal will turn ON when the command torque exceeds the threshold while the actuator is inside the check range.

5. I/O Signal Control and Signal Functions

5.3 Details of I/O Signal Functions

An input time constant is provided for the input signals of this controller, in order to prevent malfunction due to chattering, noise, etc. Except for certain signals, switching of each input signal will be effected when the signal has been received continuously for at least 6 msec. For example, when an input is switched from OFF to ON, the controller will only recognize that the input signal is ON after 6 msec. The same applies to switching of input signals from ON to OFF (Fig. 1).

Input signal

Not recognized

Recognition by controller

6 [msec] 6 [msec]

Fig. 1 Recognition of Input Signal

5.3.1. Details of Each Input Signal

 Operating mode (RMOD)

This controller has a mode selector switch on the front panel of the controller to prevent malfunction and data loss due to duplicate operations. Normally this switch should be set to the “AUTO” position when the actuator is operated in the auto mode using I/O signals exchanged with a PLC, or to the “MANU” position when the actuator is operated manually using a PC or teaching pendant. If the controller is mounted in a control panel, however, this switch is not readily accessible. Accordingly, a function has been added to allow the setting of this switch to be changed from a PLC for added convenience. Specifically, the internal operating mode of the controller will become “AUTO” when this signal is turned OFF, or “MANU” when this signal is turned ON, if the mode selector switch is set to the “AUTO” position. If the mode selector switch is set to the “MANU” position, the internal operating mode of the controller will remain “MANU” regardless of the status of this signal. Use this signal in applications where the operation mode must be switched frequently between auto and manual and the selector switch is provided on the equipment side.

Not recognized

 Start (CSTR)

Upon detecting an OFF Æ ON rise edge of this signal, the controller will read, as a binary code, the target position number consisting of six bits from PC1 to PC32 (or eight bits from PC1 to PC128 when the PIO pattern is “256-point type,” or nine bits from PC1 to PC256 when the PIO pattern is “512-point type”), and execute positioning to the target position of the corresponding position data. Before executing this command, the target position, speed and other operation data must be set in the position table using a PC/teaching pendant. If a start command is issued when home return operation has not been performed yet after the power was input (the HEND output signal is OFF), the controller will automatically perform home return operation before positioning to the target position.

 Command position number (PC1 to PC256)

When a movement command is effected upon OFF o ON of the start signal, the nine-bit binary code consisting of signals PC1 to PC256 will be read as the command position number. In the standard or teaching type, six bits of PC1 through PC32 are used. In the 256-point type, eight bits of PC1 to PC128 are used. In the 512-point type, nine bits of PC1 through PC256 are used. The weight of each bit is as follows: 2

for PC1, 21 for PC2, 22 for PC4, …, and 29 for PC256. A desired position

number between 0 and 511 (maximum) can be specified.

 Pause (*STP)

When this signal turns OFF while the actuator is moving, the actuator will decelerate to a stop. The remaining movement is retained and will be resumed when the signal is turned ON again. To abort the movement command, turn ON the alarm reset signal while this signal is OFF to cancel the remaining movement. The *STP signal can be used for the following purposes: [1] Provide a low-level safety measure to stop the axis while the servo is ON, such as a sensor that detects a

person approaching the system [2] Prevent contact with other equipment [3] Perform positioning based on sensor or LS detection (Note) If the *STP signal is input while the actuator is performing home return, the movement command will be

retained if the actuator is yet to contact a mechanical end. If the signal is input after the actuator has reversed upon contacting a mechanical end, home return will be performed again from the beginning.

 Home return (HOME)

The controller will start home return operation upon detection of an OFF o ON edge of this signal. When the home return is complete, the HEND signal will be output. The HOME signal can be input as many times as required.

 Servo ON (SON)

The servo remains ON while this signal is ON. When the power is turned on, make sure this signal will turn ON after the safety of the entire equipment is ensured, i.e., after a confirmation that the actuator will not contact surrounding equipment. If the SON signal need not be used in view of the nature of the equipment, you can disable the signal using parameter No. 21. When this signal is disabled, the servo will turn on automatically after the power is turned on. The factory setting is to enable the SON signal.

5. I/O Signal Control and Signal Functions

 Alarm reset (RES)

This signal provides two functions. [1] Reset the alarm output signal (*ALM) that turned OFF due to an alarm

If an alarm has generated, turn ON this signal after confirming the nature of the alarm. The controller will reset the alarm upon detection of a rise edge of the RES signal. (Note) Certain alarms cannot be reset by the RES signal. For details, refer to 10, “Troubleshooting.”

[2] Cancel the remaining movement when the pause signal is OFF

This function is used when the remaining movement must be cancelled to allow for incremental moves (movements at a constant increment) from the position where the actuator stopped following a sensor detection.

5. I/O Signal Control and Signal Functions

 Brake release (BKRL)

When the actuator is equipped with a brake, you may want to forcibly release the brake in certain situations such as when starting up the system for the first time. Normally the brake release switch on the front panel of the controller is set to the “RLS” side to release the brake. For added convenience, the brake can now be released from the PLC. If this signal is ON while the servo is off, the brake is released. Use this signal to provide a release switch near the actuator when the actuator is located away from the controller.

 Operation mode (MODE)

This signal is effective when the teaching type is selected. When this signal is turned ON while the actuator is standing still, the normal operation mode will change to the teaching mode. The controller will turn ON the MODES output signal upon receiving this signal. Program the PLC so that it will accept a current-position write command after confirming that the MODES output signal is ON. When this signal is turned OFF, the controller will return to the normal operation mode.

 Current-position write (PWRT)

This signal is enabled when the aforementioned MODES output signal is ON. When this signal has remained ON for 20 msec or longer, the controller will read the position number specified by a binary code consisting of PC1 through PC32 as currently detected, and write the current position data in the “Position” field of the corresponding position number. If data of other items (speed, acceleration/deceleration, positioning band, etc.) are yet to be defined, the default settings of the corresponding parameters will be written. When the writing completes successfully, the WEND output signal will turn ON. Configure the system in such a way that the PLC will turn OFF the PWRT signal when WEND turns ON. The controller will turn OFF WEND once the PWRT signal turns OFF. (Note) An alarm will generate if a write command is issued when home return has not been performed yet or

while the actuator is moving.

 Manual operation switching (JISL)

This signal is enabled when the teaching type is selected. The JISL signal is used to switch operations in the manual mode. Specifically, the actuator will jog when this signal is OFF, or inch when this signal is ON. If this signal is turned ON while the actuator is jogging, the actuator will decelerate to a stop. If this signal is turned OFF while the actuator is inching, the actuator will continue with its inching movement.

 Jog (JOG+, JOG-)

This signal is enabled when the teaching type is selected. When the actuator is jogging (i.e., the JISL signal is OFF), it will jog toward the +/- software stroke limit upon detection of an OFF Æ ON rise edge of this signal. If an ON Æ OFF fall edge of this signal is detected while the actuator is moving, the actuator will decelerate to a stop. The jogging speed is defined by parameter No. 26, “PIO jog speed.” * If any of the following input signal changes occurs while the actuator is jogging, the actuator will decelerate to a

stop:

[1] Both the JOG+ and JOG- signals have turned ON. [2] The JISL signal has turned ON (i.e., the operation mode has changed to inching). [3] The CSTR signal has turned ON (i.e., a positioning command has been input).

Upon detection of an OFF Æ ON rise edge of this signal while the actuator is inching (i.e., the JISL signal is ON), the actuator will travel the distance defined in parameter No. 48, “PIO inching distance.” The actuator will continue with its inching movement if this signal is switched while the actuator is inching.

Caution: If jogging or inching is performed before a home return is completed, the actuator may

collide with a mechanical end because the software stroke limits are not yet effective. Exercise due caution.

 Direct position command (ST0 to ST6) [7-point type]

These signals are effective when “4” is set in parameter No. 25. Upon detection of an OFF Æ ON rise edge of this signal or detection of the ON level of the signal, the actuator will move to the target position set in the corresponding position data. Before executing this command, the target position, speed and other operation data must be set in the position table using a PC/teaching pendant.

5. I/O Signal Control and Signal Functions

If ON edges of two or more signals are detected at the same time, priority will be given to the position command of the smallest number among all detected command signals. (Example: If ON edges of ST0 and ST1 signals are detected at the same time, the actuator will start moving to position 0.) Although commands are executed upon detection of an ON signal edge, priority is given to the command that was specified the earliest. In other words, a signal input will not be accepted while the actuator is moving. Even if a different position signal is turned ON while the actuator is moving, the actuator will not commence moving to the new position after reaching the target position.

If a movement command is issued when the first home return is not yet completed after the power was input, home return will be performed automatically to establish the coordinates first, after which the actuator will move to the target position.

5. I/O Signal Control and Signal Functions

 Movement to each position (ST0 to ST2) [3-point type]

Since the number of positioning points is limited to three, the actuator can be controlled just like an air cylinder. While this signal is ON, the actuator will move toward the target position. If the signal turns OFF while the actuator is moving, the actuator will decelerate to a stop. Before executing this command, enter a target position in the “Position” field for position No. 0, 1 or 2 in the position table.

ST2 Intermediate point The target position is defined in the “Position” field for position No. 2.

5.3.2 Details of Each Output Signal

 Operating mode status (RMDS)

The internal operating mode of the controller is output based on the AUTO/MANU selector switch on the controller and the RMOD signal received by the input port. If the selector switch is set to “AUTO” and the RMOD signal is OFF (AUTO), the controller is in the AUTO (OFF) mode. If the selector switch is set to “MANU” and/or the RMOD signal is ON (MANU), the controller is in the MANU (ON) mode.

 Completed position number (PM1 to PM256)

These signals can be used to check the completed position number when the PEND signal turns ON. The signals are output as a binary code. Immediately after the power is input, all of the PM1 to PM256 signals are OFF. In the standard or teaching type, six bits of PM1 through PM32 are used. In the 256-point type, eight bits of PM1 through PM128 are used. In the 512-point type, nine bits of PM1 through PM256 are used. All of these signals are OFF also when the actuator is moving. As described above, this signal is output only when positioning is completed. (Note) All of these signals will turn OFF when the servo is turned OFF or an emergency stop is actuated. They

will return to the ON status when the servo is turned ON again, provided that the current position is inside the in-position range with respect to the target position. If the current position is outside the range, the signals will remain OFF. When the power is input, the PEND signal will turn ON. These signals are all OFF, this condition is the same as one achieved after positioning to position “0” is completed.

Check the position of position 0 after the movement command has completed. If an alarm is present, the corresponding alarm code (abbreviated form) consisting of four bits from PM1 to PM8 will be output. The meanings of these signals vary between the normal condition and the alarm condition, so be careful not to use them wrongly in the sequence.

5. I/O Signal Control and Signal Functions

 Moving (MOVE)

This signal is output while the servo is ON and the actuator is moving (also during home return, push & hold operation or jogging). Use the MOVE signal together with the PEND signal to allow the PLC to determine the actuator status. The MOVE signal will turn OFF after positioning or home return is completed or a judgment is made during push & hold operation that the work part is being contacted.

 Position complete (PEND)

This signal indicates that the target position was reached and positioning has completed. Use the PEND signal together with the MOVE signal to allow the PLC to determine the positioning status. When the controller becomes ready after the power was input and the servo has turned ON, this signal will turn ON if the position deviation is within the in-position range. Then, when a movement command is issued by turning ON the start signal, the PEND signal will turn OFF. It will turn ON again when the deviation from the target position falls within the in-position range. Once turned ON, the PEND signal will not turn OFF even when the position deviation subsequently exceeds the in-position range. (Note) If the start signal remains ON, the PEND signal will not turn OFF even when the deviation from the target

position falls within the in-position range: it will turn ON when the start signal turns OFF.

Even when the motor is stopped, the PEND signal will remain OFF if the pause signal is input or the

servo is OFF.

5. I/O Signal Control and Signal Functions

 Home return completion (HEND)

This signal is OFF immediately after the power is input, and turns ON in either of the following two conditions: [1] Home return operation has completed with respect to the first movement command issued with the start

signal. [2] Home return operation has completed following an input of the home return signal. Once turned ON, the HEND signal will not turn OFF unless the input power supply is cut off, a soft reset is executed, or the home return signal is input again. The HEND signal can be used for the following purposes: [1] Check prior to establishing the home if movement toward the home direction is permitted, in cases where

an obstacle is located in the direction of the home [2] Use as a condition for writing the current position in the teaching mode [3] Use as a condition for enabling the zone output signal

 Zone (ZONE1, ZONE2)

[1] ZONE1 This signal will remain ON while the current actuator position is inside the zone specified by Parameter No. 1, “Zone boundary+” and Parameter No. 2, “Zone boundary-,” or OFF while the actuator is outside this range. This signal is always effective once home return has been completed and is not affected by the servo status or presence of an alarm. (Note) This signal becomes effective only after the coordinate system has been established following a

completion of home return. It will not be output immediately after the power is turned on.

[2] PZONE This signal will turn ON when the current actuator position enters the area between the zone boundaries set in the position table. After the current position movement command is completed, the signal will remain effective until the next position movement command is received.

 Current operation mode (MODES)

This signal is enabled when the teaching type is selected. The MODES signal will turn ON when the teaching mode is enabled upon selection of the teaching mode via the operation mode input signal (MODE signal ON). Thereafter, the MODES signal will remain ON until the MODE signal turns OFF. Configure the system in such a way that the PLC will start teaching operation after confirming that the MODES signal has turned ON.

 Write completion (WEND)

This signal is enabled only when the teaching type is selected. The WEND signal is OFF immediately after the controller has switched to the teaching mode. It will turn ON when the writing of position data in response to the current-position write signal is completed. When the current-position write signal turns OFF, this signal will also turn OFF. Configure the system in such a way that the PLC will acknowledge completion of writing when the WEND signal turns OFF.

 Movement complete at each position (PE0 to PE6) [7-point type]

When PIO pattern is “4,” a position number (0 through 6) corresponding to each movement command will be output upon completion of positioning. Simple alarm-code output function is not provided for these signals. If an alarm generates, only the *ALM signal will turn OFF. Check the details of the alarm code using each tool.

Correspondence table of output signals and positions completed

Output signal Position completed

Note) These signals turn OFF when the servo is turned OFF or an emergency stop is actuated. They will return

to the ON status when the servo is turned ON again, provided that the current position is inside the inposition range with respect to the target position. If the current position is outside the range, the signals will remain OFF.

 Position detection output at each position (LS0 to LS2) [3-point type]

These signals have the same meanings as the LS signals of an air cylinder. Each signal will turn ON when the current position enters the positioning band of the target position. (Note) Even if the servo turns off or an emergency stop is actuated while the actuator is stopped at the target

position, the signal will remain ON as long as the actuator is inside the positioning band.

 Ready (SV)

This is a monitor signal indicating that the servo is ON and the motor is ready. Use this signal as a condition for starting a movement command on the PLC side.

 Alarm (*ALM)

This signal remains ON while the controller is operating properly, and turns OFF when an alarm has generated. Provide an appropriate safety measure for the entire system by allowing the PLC to monitor the OFF status of this signal. For details of alarms, refer to 10, “Troubleshooting.”

5. I/O Signal Control and Signal Functions

 Emergency stop (*EMGS)

This signal remains ON while the controller is normal, and will turn OFF if the emergency stop circuit is cut off. Program the PLC so that it will monitor this signal and implement appropriate safety measures for the entire system if the signal turns OFF.

 Load output judgment status (LOAD)

* This is a dedicated signal available only with the PCON-CF. If used in a press-fitting application, the controller must be able to know if the specified load threshold was reached during push & hold operation. A desired load threshold and check band range are set in the position table, and this signal will turn ON when the command torque exceeds the threshold while the actuator is inside the check band range. With the LOAD signal, judgment is made based on whether the total duration of periods in which the command torque has exceeded the threshold corresponds at least to a specified time. The specific processing procedure is the same as the one used when determining a completion of push action. The time used for judgment of load output can be changed freely using user parameter No. 50, “Load output judgment time.”

 Torque level status (TRQS)

* This is a dedicated signal available only with the PCON-CF. If a load threshold is set, this signal will turn ON when the motor current reaches the load threshold while the actuator is moving. Since the level of current is monitored, the ON/OFF status of this signal will change when the current changes. In the weak field-magnet vector control used for stepping motors, the balance of current and torque will be lost once a specific speed is exceeded. To use the command current to determine if the threshold has been reached, therefore, the push speed must be limited. Note, however, that the range of permissible push speeds varies depending on the motor and lead, which means that the push speed set in user parameter No. 34 must also be adjusted according to the applicable motor and lead.

6. Data Entry <Basics>

To move the actuator to a specified position, a target position must be entered in the “Position” field. A target position can be specified in the absolute mode where a distance from the home is entered, or in the incremental mode where a relative travel from the current position is entered. Once a target position is entered, all other fields will be automatically populated with their default values set by the applicable parameters. The default values vary depending on the characteristics of the actuator.

 Set a positioning band slightly longer than the last position, in order to absorb possible mechanical variation

of the work part.

6. Data Entry <Basics>

 “Completion of push action” is determined based on a combination of the current-limiting value set in the

“Push” field of the position table and the push completion judgment time set by parameter No. 6. Set an appropriate condition by considering the material and shape of the work part, among others. For details, refer to Chapter 8, “Parameter Settings.”

x The actuator continues to push the work part at the push force at standstill determined

by the current-limiting value. Since the actuator is not inactive, exercise due caution when handling the machine in this condition.

(2) Work part was not contacted (missed)

If the actuator does not still contact the work part after having moved the distance specified in the “Positioning band” field, the position complete signal will not turn ON. Therefore, include timeout check processing in the sequence circuit on the PLC side. x It is recommended that a zone signal be also used as a “simple ruler” to supplement the judgment of missed

(3) Work part moves during push & hold operation

[1] Work part moves in the pushed direction

If the work part moves in the pushed direction after completion of push action, the actuator will chase the work part within the positioning band. If the current drops to below the current-limiting value set in the “Push” field of the position table while the actuator is moving, the position complete signal will turn OFF. The position complete signal will turn ON when the current-limiting value increases to the specified level again.

Speed

[2] Work part moves in the opposite direction

(Actuator is pushed back by the strong reactive force of the work part) If the actuator is pushed back after completion of push action because the reactive force of the work part is greater than the thrust force of the actuator, the actuator will be pushed back until its push force balances out with the reactive force of the work part.

Caution: As the maximum push distance is approached during push-motion operation, the actuator

decelerates by assuming that it has missed the work part and stops at the position corresponding to the maximum push distance. If the speed drops significantly immediately before the actuator stops, the set push force cannot be maintained. For this reason, do not perform any push-motion operation where the entire range of the maximum push distance is used.

 The push speed is set by parameter No. 34, “Push speed.” The factory setting varies with each actuator in accordance with the characteristics of the actuator.

Set an appropriate speed by considering the material and shape of the work part, among others. Take note, however, that the maximum speed is limited to 10 mm/s.

6.2.4 Speed Change during Movement

Speed control involving multiple speed levels is possible in a single operation. The actuator speed can be decreased or increased at a certain point during movement. However, the position at which to implement each speed change must be set.

6.2.5 Operation at Different Acceleration and Deceleration Settings

If the work part is a CCD camera or other precision equipment, the deceleration curb at stop must be made as gradual as possible. To accommodate these sensitive applications, the position table has separate fields for “acceleration” and “deceleration.” For example, you can set the deceleration differently from the acceleration, such as setting 0.3 G (rated acceleration) in “Acceleration” and 0.1 G in “Deceleration.”

Caution: Basically, the acceleration and deceleration should be inside the rated

acceleration/deceleration range specified in the catalog. The input range is greater than the rated range in the catalog, but this is only to accommodate situations where you want to “reduce the tact time when the transferring mass is significantly smaller than the rated value.” If you want to use acceleration/deceleration settings greater than the rating, consult IAI beforehand because it may affect the life of the actuator.

6.2.6 Pause

The actuator can be paused during movement using an external input signal (*STP). The pause signal uses the contact b logic (always ON) to ensure safety. Turning the *STP signal OFF causes the actuator to decelerate to a stop. When *STP is turned ON subsequently, the actuator will resume the remaining movement.

6.2.8 Home Return

After the power is turned on, home return must be performed to establish the home position.

The method of home return varies depending on the PIO pattern. z When a dedicated input is used [PIO pattern z 5]

Home return is performed using the home return (HOME) input. The actuator will return home regardless of whether or not home return has been completed once before. When home return is completed, the home return complete (HEND) output signal will turn ON.

z When a dedicated input is not used [PIO pattern = 5]

When a rear end move command is input while home return is not yet completed, the actuator will perform home return first and then move to the rear end.

 For details, refer to 7.2, “How to Execute Home Return.”

6.2.9 Overview of Teaching Type

Depending on your system, it may be desirable to be able to use a touch panel, etc., to perform jogging operation or write the current position to the “Position” field of the position table, without using a PC or teaching pendant. The teaching type is provided to support these applications. The features of the teaching type are summarized below: [1] The actuator can be jogged using I/O signals input from the PLC.

Continuous jog feed or inching feed can be selected by the manual switching signal to facilitate fine position

adjustment.

* This function is effective regardless of the ON/OFF state of the operation mode input (MODE) signal. [2] The current position can be written to the “Position” field of the position table using I/O signals input from

the PLC.

* This function is effective only when the operation mode input (MODE) signal is ON.

(Note) The number of I/O points is limited, so some I/O ports are used in both the teaching type and the normal

positioning type. Remember this when creating a sequence circuit for the PLC.

Operation mode input (MODE) * Signal for switching to the teaching mode

Current operation mode output (MODES) * Monitor output indicating the internal

mode of the controller

6.2.10 Overview of 7-point Type

The number of positioning points is kept small, or specifically to seven or less. This type assumes simple applications where the PLC ladder sequence only requires a simple circuit configuration. I/O signals provide separate command inputs and movement complete outputs for respective position numbers. Accordingly, the signal pattern is different from the one in the 64-point positioning type (PIO pattern = 0).

Example) The differences are explained by using an example of moving the actuator to the target position for

position No. 5.

Combination of dedicated movement command input and complete output

* In the 64-point type, a position command input (binary) signal and a start input signal must be turned ON at

staggered timings to initiate movement (refer to the next page). In this type, however, there is only one input signal that needs to be turned ON.

6.2.11 Overview of 3-point Type

This type provides a control method adjusted to that of an air cylinder by assuming that the controller is used as an air cylinder. The key differences between this controller and an air cylinder are summarized in the table below. Program appropriate controls by referring to this table. * Do not use this mode for push & hold operation.

Acceleration/ deceleration setting

Determined in accordance with the load, supplied air volume, as well as the performance of the speed controller and electromagnetic valve.

Determined based on the internal coordinates provided by the position information from the position detector (encoder). Accordingly, external detection sensor is not required.

A desired feed speed is entered in the [Speed] field of the position table (unit: mm/sec). Note that the rated speed is automatically set as the initial value.

Desired acceleration/deceleration are entered in the [Acceleration] and [Deceleration] fields of the position table (minimum setting unit: 0.01 G). Reference: 1 G = Gravitational acceleration Note that the rated acceleration/deceleration is automatically set as the initial value. Since the acceleration/deceleration can be set in fine steps, a gradual acceleration/deceleration curve can be programmed.

Acceleration

0.3G

Starting position of movement

Deceleration

Ending position

Setting a larger value makes the curve steeper, while setting a smaller value makes the curb more gradual.

Item Air cylinder RCP2 Position check upon power ON

Determined by an external detection sensor, such as a reed switch.

Immediately after the power is turned on, the controller cannot identify the current position because the mechanical coordinates have been lost. Accordingly, a rear end command must always be executed after the power is turned on, to establish the coordinates. The actuator will perform home-return operation first, and then move to the rear end.

[1]

6. Data Entry <Basics>

The relationship of each movement command input/position detected and corresponding position number is shown below. The input/output signals are given easy-to-identify names by following the naming convention of air-cylinder switches. However, the target position is determined by the value set in the [Position] field for each position number. Therefore, changing the magnitude relationships of settings under position Nos. 0, 1 and 2 will change the meanings of input/output signals. For this reason, it is recommended that you always use the signals under their names defined in this manual, unless doing so presents problem, so that the signals have the same meanings at all time.
