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+ Zone setting-” A zone signal is not output.
V0016 and later: “Zone setting+ = Zone setting-” 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 0
position in the index mode.
An example is given below.

CAUTION
1. 24-V Power Supplies Required for UL Certification
PCON controllers (PCON-C/CG, CY, SE, PL/PO) are UL-certified, where one condition for the
certification is to use Class 2 24-V power supplies.
Accordingly, you must use Class 2 power supplies for both the input power supply and I/O power
supply for your equipment incorporating the PCON, if the equipment as a whole must be UL-certified.
2. Use Environment
PCON controllers can be used in an environment of pollution degree 2 or equivalent.
3. 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.
Model Remarks
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
4. 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 in the event of power failure, or 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] Hand write the position table and parameter table on paper.
All are compatible with existing RCP2
controllers
CAUTION
5. 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.
Feature of PIO pattern
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.
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].”
6. Using a Rotary Actuator in Multi-rotation Specification
Rotary actuators of multi-rotation specification models let you select multi-rotation operation or limitedrotation operation using a parameter.
6.1 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)
The index mode cannot be selected for rotational axes of simple absolute unit specification.
Accordingly, these axes cannot be specified for multi-rotation specification.

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.
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.
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.
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.
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.
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.
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.”
* We have made every effort to ensure precision of the information provided in this manual. Should you
find an error, however, or if you have any comment, please contact IAI.
Keep this manual in a convenient place so it can be referenced readily when necessary.

particular, exercise caution when
your system has a remote sensing
function.
Caution: Position data, parameters, etc., are written to the EEPROM. Take note
that the EEPROM can be rewritten for up to approx. 100,000 times.

Explanation of each switch
[1] Address switch
If multiple axes are used, the PC/teaching pendant must be plugged into/out of different connectors
to communicate with different axes.
To save the hassle, you can use link cables to connect all axes via SIO converters.
Under this method, however, the PC/teaching pendant must be able to identify each axis by the
number assigned to the axis.
This switch is used to set this number.
For details, refer to Chapter 9, “How to Connect a PC/Teaching Pendant to Multiple Axes.”
[2] Mode selector switch
This interlock switch is used to prevent unexpected movement or data rewrite as a result of duplicate
operation in which a movement command is input from the PLC and operation using the PC/teaching
pendant is performed at the same time.
AUTO: Always set to the “AUTO” side during auto operation using PIO signals from the PLC.
MANU: Always set to the “MANU” side during operation using the PC/teaching pendant.
[3] Brake release switch
When the actuator is equipped with a brake, this switch is used to forcibly release the brake.
RLS: Forcibly release the brake
NOR: Normal setting (The brake is released by the controller.)
Warning: The load may suddenly drop when the brake is forcibly released, so exercise due caution
not to pinch your hand or damage the robot hand by the falling load.
Provide a contact output for the emergency-stop button on the teaching pendant.
S1, S2
* Whether or not a teaching pendant is connected is determined by an internal
circuit. If no teaching pendant is connected, the S1 and S2 terminals are closed.
Provide a contact for cutting off the motor drive power. MPI and MPO represent the
MPI, MPO
input side and output side of the motor power supply, respectively. (Short these
terminals using a jumper wire if not used. The controller is shipped with MPI and MPO
shorted.)

3. Installation and Noise Elimination
Pay due attention to the installation environment of the controller.
3.1 Installation Environment
(1) When installing and wiring the controller, do not block the cooling ventilation holes. (Insufficient
ventilation will not only prevent the controller from demonstrating its full performance, but it may also
cause breakdown.)
(2) Prevent foreign matter from entering the controller through the ventilation holes. Since the enclosure
of the controller is not dustproof or waterproof (oilproof), avoid using the controller in a place subject
to significant dust, oil mist or splashes of cutting fluid.
(3) Do not expose the controller to direct sunlight or radiating heat from a large heat source such as a
heat treatment furnace.
(4) Use the controller in an environment free from corrosive or inflammable gases, under a temperature
of 0 to 40C and humidity of 85% or less (non-condensing).
(5) Use the controller in an environment where it will not receive any external vibration or shock.
(6) Prevent electrical noise from entering the controller or its cables.
3.2 Power Supply
The power supply specification is 24 VDC 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 mm2 or 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.

[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.
[1] AC solenoid valves, magnet switches and relays
Measure: Install a surge absorber in parallel with the coil.
[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.
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.
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.
13
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 40C.
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.
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.

5.2 PIO Patterns and Signal Assignments
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 features of each PIO pattern are explained below:
Parameter No.
25 setting
0
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.
1
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.
2
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).
3
512-point mod (512-point positioning)
The number of positioning points is increased to 512, so no zone output is available.
4
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.
5
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.
Quick reference table for functions available under each PIO pattern (: Available, X: Not available)
(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.

5.3 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).
Recognition by controller
Input signal
Not recognized
Not recognized
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.
Start (CSTR)
Upon detecting an OFF 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 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
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 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.
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.
49
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.

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 ON rise edge of this signal.
If an ON 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 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 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.
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.
51
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.

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.
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 load 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.
53
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.
54
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

PE0 Position No. 0
PE1 Position No. 1
PE2 Position No. 2
PE3 Position No. 3
PE4 Position No. 4
PE5 Position No. 5
PE6 Position No. 6
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 in-position 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.
Output signal Position detected Remarks

The detection position is defined in the “Position” and “Positioning
band” fields for position No. 2.
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.”
55
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.

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 to
accommodate situations where you want to “reduce the tact time when
the load mass is significantly smaller than the rated load capacity.”
If vibration of the load causes problem during acceleration/deceleration,
decrease the set value.

Caution: Refer to the attached list of supported actuator specifications and set appropriate speed
and acceleration/deceleration so that the actuator will not receive excessive impact or
vibration under the applicable installation condition and for the load of the specific shape.
Increasing the speed and acceleration/deceleration may significantly impact the actuator
depending on the load mass, and the actuator characteristics also vary from one model to
another. Contact IAI for the maximum limits that can be entered in your specific
application.

and “push & hold operation.”
“Positioning operation”
This field defines how much before

“Push & hold operation”
This field defines the maximum push distance after reaching the target
position in push & hold operation.
Consider possible mechanical variation of the load and set an appropriate
positioning band that will prevent the positioning from completing before
the load is contacted.
The position complete signal turns ON here, as completion of
push action is recognized after the load has been contacted.

(8) Zone +/-
This field defines the zone within which the position zone output signal
(PZONE) will turn ON. To add flexibility, a different zone can now be set
for each target position.
This field defines whether the position is specified in the absolute mode

Holding current can be reduced by servo-controlling the pulse motor.
Although the exact level of current reduction varies depending on the actuator model, load condition,
etc., the holding current will decrease by approx. 1/2 to 1/4.
Since the servo remains on, position deviation will not occur.
The actual holding current can be checked in the current monitor screen of the PC software.
Automatic servo-off mode
After positioning is completed, the servo will turn off automatically upon elapse of a specified time.
(Since no holding current generates, power consumption will decrease.)
When the next movement command is received from the PLC, the servo will turn on and the actuator
will start moving.

6.2.2 Push & Hold Mode Push = Other than 0
(1) Load was contacted successfully
Upon reaching the target position set in the “Position” field of the position table, the actuator moves at the
push speed for the distance set in the “Positioning band” field.
If the actuator contacts the load while moving and the controller recognizes that “push action has
completed,” the position complete signal will turn ON.
Speed
Moving distance
The push speed is set by parameter No. 34.
The factory setting varies with each actuator in accordance with the actuator’s characteristics.
Set an appropriate speed by considering the material and shape of the load, among others.
Since the maximum speed is 20 mm/s, operate the actuator at a speed not exceeding this value.
Set a positioning band slightly longer than the last position, in order to absorb possible mechanical
variation of the load.
“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 load, among others.
For details, refer to Chapter 8, “Parameter Settings.”
The position complete signal turns ON here,
as completion of push action is recognized
after the load has been contacted.

Warning
66
If the actuator contacts the load before reaching the target position, a servo error alarm
will generate. Pay due attention to the relationship of the target position and the load
position.
The actuator continues to push the load 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) Load was not contacted (missed)
If the actuator does not still contact the load 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.
It is recommended that a zone signal be also used as a “simple ruler” to supplement the judgment of
missed load.

If the load moves in the pushed direction after completion of push action, the actuator will chase the
load 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.

(Actuator is pushed back by the strong reactive force of the load)
If the actuator is pushed back after completion of push action because the reactive force of the load
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 load.
The position complete signal will remain ON.

threshold before the specified distance is traveled and while the actuator is inside the threshold check
band, the load output will turn ON.
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 load, among others.
Take note, however, that the maximum speed is limited to 10 mm/s.
Set parameter No. 51, “Torque check range” to “0 [Enable].”
Set a threshold check band in the "zone + or zone -" filed of the position table.

within the specified push force range).
Set a desired positioning band in the “Positioning band” field of the position table.
Set a positioning band slightly longer than the last position, in order to absorb possible mechanical
variation of the load. For details, refer to Chapter 8, “Parameter Settings.”

After reaching the target position set in the “Position” field of the position table, the actuator moves at the
push speed by the distance set in the “Positioning band” field. If the command torque reaches the
threshold before the end of the positioning band is reached, the load output will turn ON. The load output
will turn OFF once the command torque drops to below the threshold.
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 load, among others.
Take note, however, that the maximum speed is limited to 10 mm/s.
Set parameter No. 51, “Torque check range” to “1 [Disable].”
Set a desired threshold in the “Threshold” field of the position table (input range: a desired value

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.
Position 1 Position 2 Position 1 Position 2 Position 1 Position 2 Position 3
6.2.5 Operation at Different Acceleration and Deceleration Settings
If the load 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.”
Speed
Starting

cceleration:
0.3 G
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 load mass is
significantly smaller than the rated load capacity.”
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.

(Note) The deceleration corresponds to the value set in the “Deceleration” field for the current position
number in the position table.
6.2.7 Zone Signal Output
The zone output is suitable for the following applications, because a signal can be output when the
actuator enters a specified zone during movement:
[1] Issue a trigger signal to surrounding equipment to reduce the tact time
[2] Prevent contact with surrounding equipment
[3] Use as a “simple ruler” in push & hold operation
A different method is used for the zone output signal, and for the position zone output signal, to set the
zone within which the signal will turn ON.

Set the signal ON zone using parameters.

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.
When a dedicated input is used [PIO pattern 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.
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

Warning: Jog commands are effective even before home return is completed, but the soft stroke
checks are not performed prior to home return. Accordingly, the actuator may move all
the way to the mechanical end if the jog command (JOG+/JOG-) signal remains ON.
Exercise caution not to let the actuator hit the mechanical end.

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.

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.

Desired coordinates are entered in the [Position] field of the

Coordinates can be entered from the PC/teaching pendant
using the keyboard/keys, or the actuator can be moved to the
desired position to read the achieved coordinates directly.

Accordingly, external detection sensor is not required.
A desired feed speed is entered in the [Speed] field of the

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

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] The actuator moves at the home return speed toward the
mechanical end on the motor side.
[2] The actuator contacts the mechanical end and turns back,
and then stops temporarily at the home position.
[3] The actuator moves to the rear end at the speed set in the
[Speed] field of the position table.
(Note) Pay attention not to allow any obstacle in the travel path
of the actuator during home return.
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.

The specified stroke of the 2-finger type indicates the sum of travel distances of both fingers. In
other words, the travel distance of one finger is one half the specified stroke.
A position you specify defines the distance traveled by one finger from the home position in the
closing direction.
Accordingly, the maximum command value is 5 mm for the GRS type and 7 mm for the GRM type.
[2] Definition of speed and acceleration
The command value applies to each finger.
The relative speed and acceleration of the 2-finger type are twice the command values.
[3] Operation mode in gripper applications
When the actuator is used to grip the load, be sure to select the “push & hold mode.”
(Note) In the “positioning mode,” a servo error may occur while the load is gripped.

6.4 Power-saving Modes at Standby Positions
One general feature of pulse motors is that their holding current in standstill state is greater than AC servo
motors.
Therefore, this product provides energy-saving modes to reduce power consumption in situations where
the actuator remains standstill for a long period at a standby position.
Use these modes after confirming that they will not present problems to any part of your system.
Each mode produces a different level of power-saving effect. Follow the instructions provided below and
select an optimal mode appropriate for the specific standstill condition of your actuator.
The actuator stands by with the servo on after the power has been turned on
In this condition, you can select full servo control using parameter No. 53 (Default standstill mode).
Automatic servo-off control cannot be selected. If you have set 1, 2 or 3 by mistake, the setting will be
ignored.
(This setting is not affected by the value in the “Standstill mode” field of the position table.)
The actuator stands by after completing the positioning to the target position set in the “Position” field
for the applicable position number
In this condition, you can select one of two modes based on the value in the “Standstill mode” field of the
position table.
(This setting is not affected by the value of parameter No. 53.)
[1] Full servo control
[2] Automatic servo-off control
PIO pattern = Other than 5: Solenoid valve mode 2 [3-point type]
The actuator stands by after completing the home return operation effected by the HOME input signal
In this condition, you can select one of two modes based on the value of parameter No. 53 (Default
standstill mode).
(This setting is not affected by the value in the “Standstill mode” field of the position table.)
[1] Full servo control
[2] Automatic servo-off control
The actuator stands by after completing the positioning to the target position set in the “Position” field

80
Full servo control mode
The pulse motor is servo-controlled to reduce the holding current.
Although the exact degree of current reduction varies depending on the actuator model, load condition,
etc., the holding current decreases to approx. 1/2 to 1/4.
Since the servo remains on, position deviation will not occur.
The actual holding current can be checked in the current monitor screen of the PC software.
Take note that micro-vibration or noise may occur in certain conditions where external force is applied, or
depending on the position where the actuator has stopped.
If micro-vibration or noise presents problem, do not use this mode.
Automatic servo-off mode
After positioning is completed, the servo will turn off automatically upon elapse of a specified time.
(Since no holding current flows, power consumption will decrease.)
When the next movement command is received from the PLC, the servo will turn on and the actuator will
start moving.
* Since the servo turns off once, some position deviation may occur. Do not use this function at standby
positions where position deviation will cause problem.
You should also note that the position complete (PEND), completed position number (PM1 to PM256) and
movement complete (PE0 to PE6) signals will turn OFF because the servo turns off. However, you can
keep the signals ON via a parameter in situations where the PLC sequence circuit is designed in such a
way that problems will occur if complete signals turn OFF.
Setting of parameter No. 39
(Output mode of position
complete signal)
[1] PIO pattern = 0 to 3
Position complete (PEND) signal status, completed position number (PM1
to PM256) signal status
[2] PIO pattern = 4
Position complete (PEND) signal status, movement complete (PE0 to
PE6) signal status
0 [PEND] The signal will turn OFF unconditionally when the servo turns off.
Even when the next movement command is issued and the servo turns on
again, the actuator has already started moving to the next target position,
so the signal still remains OFF.
1 [INP] Even when the servo is off, the signal turns ON if the current position is
within the range set by the “Positioning band” field of the position table,
with respect to the target position, and turns OFF if the current position is
outside this range.
(Note) The factory setting is “0.”
