2. Product Outline

2.1 Product features

The followings are the main functions of this driver:



Electric Actuator Control

Positioning operation and Pushing operation, at a specific speed and force, of the electric actuator

are possible by controlling the Step motor (24 VDC servo).



Separated power supply

The power supply is separated into the drive power and the control power. Therefore, even when the drive power is off, if the control power is on, the position information from the encoder will be

maintained and the serial communication and parallel I/O control are still available.



Return to origin Return the electric actuator to the home position by sending a single signal to a dedicated terminal.



Alarm detection function

Automatically detect the abnormal conditions and output the appropriate alarm signal via the serial

interface and parallel I/O. The alarm information (up to the last 8 alarms) will be recorded into the

memory in the driver.



Data input method

It is possible to perform parameter setup, status monitoring, trial run and alarm reset via the serial

communication with a PC installed with the controller setting kit or the teaching box.



Specified force operation Control the pushing force (or the pressing force) of the electric actuator.

Caution

The operation with specified thrust is available for driver version 1.60 or more.

Please refer to the “3.2 Parts description (page 13)” for the confirm method of the driver version.

Please keep this manual safe for future use. It will be necessary to refer to this manual along with the operation manuals for other electric actuators, teaching box, and controller setting kit at installation and fault

finding. Keep this operation manual accessible for reference.

Caution

For driver input power supply (24 VDC) use a power supply with a capacity not less than the

“momentary maximum power” of the electric actuator spedfications. Do not use “inrush current restraining type” power supply.

(2) Wiring of the stop switch

By connecting 24V to EMG, motor becomes operable. Without connect the 24V to EMG, motor does not

move. Stop switch must be installed by the user to stop the electric actuator in abnormal situations. Please refer to “5.4 Stop circuits” for examples of how to wire stop switches.

Caution

The Servo is not ON unless a voltage of 24 VDC is applied to the EMG terminal.

(3) Wiring of the lock release

Install an unlocking switch for adjustment or recovery during an emergency of the electric actuator with

lock. The switch (24 VDC, Contact capacity: 0.5A or more) should be obtained separately.

One terminal of the lock release switch should be connected to the 24 VDC power supply and the other

should be connected to the BK RLS terminal. When this is switched on, the lock will be released forcibly.

Warning

(1) Relay contacts should be made between the 24 VDC driver power supply and the M24V and

EMG terminal of the power supply plug. The electric actuator may make unexpected movement.

(2) When at the same time to OFF EMG and the power, For the inertia of the load, you might have to

take time until the motor stops.

(3) Do not perform return to origin (SETUP input ON) when motor drive power (M24V) is

disconnected. The driver cannot recognize the correct origin point if a return to origin instruction

is made with the motor drive power (M24V) disconnected.

(4) If the electric actuator with lock is used vertically, delay in response of the brake may occur when

shutting off the motor power supply (M24V), and the moving part of the electric actuator may

drop due to the weight of the electric actuator itself.

(5) Do not energize to the BK RLS terminal when there is a necessity to shut down the motor drive

power (M24V) externally.

Because the BK RLS terminal is connected with M24V in the driver, the electric actuator may do

unexpected operation. Please turn off the EMG terminal when energizing to the BK RLS terminal

at motor drive power is OFF.

to home position, this terminal is turned ON. However, the SETON output is turned OFF in the following condition.

1. Servo is OFF (SVRE output is OFF)

2. Alarm generated

3. CLR input is ON (including the return-to-origin operation, after TLOUT ON

during pushing operation)

4. When it is in the condition above following the test operation from the controller setting kit/teaching box, the pulse instruction signal from a PLC (such as the positioning unit) differs from the positioning information inside

the driver. This turns the SETON output OFF.

16

INP

Because of the electric actuator action, if INP signal is ON, the electric actuator

condition can vary.

1. Return to origin

The output signal INP turns ON when the electric actuator operation stops (BUSY output is OFF) and the position is within the range of the origin

position ±basic parameter “initial positioning range”.

2. During positioning operation

If pulse signal is not input for 10ms or longer, INP signal is ON when the

difference becomes smaller than the step data No.0 "positioning width".

3. During pushing operation

Turns on when the pushing force exceeds the value set in the step data

No.0.

Caution

If "positioning width" of the step data No.0 is too large during slow movement of the electric actuator, INP signal may be ON even if the

positioning of the electric actuator is not completed.

17

SVRE

When the servo motor is ON, SVRE is ON. When the servo motor is OFF, SVRE is OFF.

*1)

18

*ESTOP

*2)

ESTOP is ON during normal operation.

During activation of Teaching Box stop switch or by the stop command, this

terminal is OFF.

19

*ALARM

*2)

When there are no alarms, this terminal is ON. When there are alarms, this is OFF.

20

AREA

When the electric actuator is within the output range between Area1 and Area2 in the step data No.0, this terminal will be turned ON. Note that when the

SETON output is OFF, the AREA signal will also be OFF.

*1) It maybe takes about ten seconds from turning on SVON to SVRE turned on when after the power

supply.

*2) The “ALARM” and “ESTOP” become the negative-true logic output.

7. Setting Data Entry

For the controller setting kit and the teaching box, there are two available modes. The appropriate mode

can be selected depending on the purpose.

● Easy mode

In Easy mode, the electric actuator can be started by entering only a limited number of settings with

the controller setting kit and the teaching box.

The combination of settings you need to set up will change depending on the type of electric actuator.

(combination of data can be selected.)

● Normal mode

In Normal mode, a more detailed setup can be made (conditions for the electric actuator and driver,

etc.) than in Easy mode.

You can change three kinds of setting data, “Step data,” “Basic parameter” and “Return to origin

parameter” in this mode.

7.1 Step data

Step data describes the data that sets items of operation (such as positioning width) excluding speed, position, acceleration, and deceleration, which are determined by the pulse-signal input. Step data will

become effective as soon as it is recorded into the driver.

Each data is set by step data No.0. “Pushing force”

*1)

, “Trigger LV”

*1)

, “Pushing speed”

8. Operations explanation

8.1 Return to origin

After entering the setting data, it is necessary to perform a return to origin operation before starting the

positioning or pushing operation. (To ensure the position of origin) There are two types of return to origin operation.

(1) Return to origin mode using LECPA SETUP signal

The electric actuator moves in the return to origin direction (this direction is dependent on the electric

actuator) from the initial position at the moment of power-on: See (1) in the diagram below.

When the electric actuator reaches the end of travel limit it pauses for a short time. The driver

recognizes the position as the end of travel limit of the electric actuator. Then, the electric actuator

moves at a low speed in the direction opposite to the return to origin direction: See (2) in the diagram

below.

Caution

This direction is dependent on the electric actuator.

(2) Return-to-origin function of PLC (such as a positioning unit)

Refer to the PLC operation manual (such as a positioning unit). When using the return-to-origin

function of the PLC (such as a positioning unit), the LECPA’s SETON is always turned OFF.

8.2 Positioning operation

8.3 Pushing operation

1. During operation at "Pushing speed" of Step Data No.0 or less, or the electric actuator is stopping.

2. TL input turns on

When above two conditions are satisfied, operation is switched to pushing operation (pushing force). The

electric actuator pushes the load with the force no more than the maximum pushing force set in the

“Pushing force” of the step data No.0. TLOUT is turned ON during pushing operation.

However, after switching to the pushing operation (TLOUT output is ON), the actuator operates at the

"Pushing speed" set in Step Data No.0 even if pulse signals exceeding the "Pushing speed" of Step Data

No.0 are input.

(1) Pushing operation is successfully performed

During the pushing operation, if the pushing force is kept higher than the value specified by “Trigger LV”

of the step data No.0 for a certain time, the INP output will be turned ON. Set thrust continues to be

generated even after the pushing is completed.

(3) Movement of the work piece after the completion of the pushing process

(i) The workpiece moves in the pushing direction.

After completion of the pushing operation, if the reaction force from the workpiece becomes smaller, the electric actuator may move with a force smaller than that specified in the “Trigger LV” of the step data. In such case, the BUSY output will be turned ON and the INP output will be turned OFF and the

electric actuator moves within the positioning range according to the balance of the force.

During the pushing operation, if the pushing force is kept higher than the value specified by “Trigger LV” of the step data No.0 for a certain time again, the INP output will be turned ON and BUSY output

will be turned OFF.

(ii)When the electric actuator moves in the opposite direction of pushing direction

8.4 Response time for the driver input signal

Response delay due to the input signal other than pulse signal contains the following factors.

(1) Driver input signal scan delay (2) Delay due to input signal analysis (3) Delay of command analysis

Leave an interval of 15 ms (30 ms if possible) or more between input signals and maintain the state of the

signal for 30ms or more, as PLC processing delays and driver scaning delays can occur.

8.5 Methods of interrupting operation

It is possible to stop the electric actuator by interrupting the movement of a positioning operation or

pushing operation.

[Stopping by EMG signal]

If the EMG signal is turned OFF during operation, after the electric actuator decelerates and stops, the servo will turn OFF so the stopped position is not held. (For the electric actuator with lock, it is held by the

lock function.) Pulse signal input is ignored while EMG signal is OFF because the servo is OFF.

11. Automatic pulse reference detection

11.1 The meaning of automatic pulse reference detection

This function checks the state of no pulse inputs when the first SVON input is ON, and then detects the

state of the pulse input circuit (photo coupler ON/OFF). This takes priority over the set value determined

by the parameter (Option set 1) to set the pulse-signal input method. (This detection is "H/L reference " only. "Pulse Input Method" cannot be detected.) When the first SVON input is ON during the pulse inputting, the H/L reference cannot be detected.

If the H/L reference cannot be detected correctly, please refer to "11.3 Automatic pulse reference

detection OFF"

11.2 Operation procedure using automatic detection function

Manual.

Incorrect handling can cause injury, damage or malfunction of equipment and machinery.

2. Removal of product.

When equipment is serviced, first confirm that measures are in place to prevent dropping of work pieces and run-away of equipment, etc, then cut the power supply to the system. When machinery is

restarted, check that operation is normal with electric actuators in the proper positions.

3. Remove the actuator cable when manually operating the actuator slider.

If the slider is moved manually while the electric actuator is connected to the driver, a motor-induced voltage will enter the driver to prevent the slider from moving smoothly. If the slider is frequently moved

manually, the driver may be damaged due to this induced voltage.

[Lubrication]

Caution

1. The product has been lubricated for life at the manufacturer's and does not require lubrication

in service.

Contact SMC if lubrication will be applied.

14.6 Precautions for electric actuator with lock

Warning

1. Do not use the lock as a safety lock or a control that requires a locking force.

The lock used for the product with a lock is designed to prevent dropping of work piece.

2. For vertical mounting, use the product with a lock.

If the product is not equipped with a lock, the product will move and drop the work piece when the

power is removed.

3. "Measures against drops” means preventing a work piece from dropping due to its weight

when the product operation is stopped and the power supply is turned off.

4. Do not apply an impact load or strong vibration while the lock is activated.

If an external impact load or strong vibration is applied to the product, the lock will lose it’s holding force and damage to the sliding part of the lock or reduced lifetime can result. The same situations will happen when the lock slips due to a force over the thurst of the product, as this accelerates the

wear to the lock.

5. Do not apply liquid or oil and grease to the lock or its surrounding.

When liquid or oil and grease is applied to the sliding part of the lock, its holding force will reduce

significantly.

6. Take measures against drop and check that safety is assured before mounting, adjustment

and inspection of the product.

If the lock is released with the product mounted vertically, a work piece can drop due to its weight.

7. When the electric actuator is operated manually (when SVRE output signal is off), supply 24

VDC to the [BK RLS] terminal of the power supply connector.

If the product is operated without releasing the lock, wear of the lock sliding surface will be

accelerated, causing a reduction in the holding force and the life of the locking mechanism.

8. Do not supply 24 VDC continuously to the [BK RLS(Lock release)] terminal.

Stop supplying 24 VDC power supply to the [BK RLS(Lock release) terminal during normal operation. If power is supplied to the [BK RLS] terminal continuously, the lock will be released, and workpieces

- 76 -

may be dropped at stop (EMG).

Voltage drop

Check for a temporary voltage drop in the power

supply.

(When a voltage dropoccurs, the EMG terminal of the CN1 power connector will turn OFF and the electric actuator will stop. However, this stop will be released when

the voltage recovers).

A momentary voltage drop may have occurred because the power supply capacity is inadequate or the power supply

is an inrush current suppressor type.

→ 3. Product Specifications Inappropriate specifications

correct?

Check if the product number of the used electric actuator matches with the electric actuator which is applicable to the driver. → 3. Product Specifications

Signal timing

Check the timing of the signal from the PLC to the driver.

Leave an interval of a minimum of 15 ms (recommendation is 30 ms) between input signals and maintain the state of the signal for a minimum of 15 ms (recommendation is 30 ms), because PLC processing delays

and driver scanning delays can occur. → 8.4 Response time for the driver input

signal

Pushing

operation

Check that the TLOUT output is ON during a

pushing operation.

In any of the following conditions, the

TLOUT signal is turned OFF.

1. Alarm sounds: When an alarm sounds,

turn OFF the TL input, and then turn it

ON again.

2. Return to origin command: During return

to origin, do not turn ON the TL input. Also, if you command a return-to-origin during pushing, turn OFF the TL input

and then turn it ON again.

3. Do not turn on TL input while the servo is

OFF (SVRE output is OFF). Signal is not

recognized.

SVON time

Check if the electric actuator is operated when the SVRE output is turned on after the SVON input is

turned on.

When power is applied, it may take up to 10 seconds (max. 20 sec.) from SVON input to SVRE output depending on the electric actuator position. Command operation after SVRE output is turned ON.

Alarm condition

Is driver alarm generated?

Refer to the driver operation manual, and take appropriate measures. Take appropriate measures based on the operation manual. → 12. Alarm Detection

- 84 -

4

The electric actuator does not move to the correct position.

Incorrect origin position

If it is a pushing operation, repeat return to origin operations several times to check if the electric actuator returns to the origin correctly.

Perform the return to origin position operation several times to check the origin position. Take measure to make the electric actuator operates normally (remove foreign matters that interferes with the electric actuator movement, etc.)

Inappropriate basic parameters

Check that the parameter values are appropriate and the program is correct.

Check the max. speed, acceleration speed, and deceleration speed of the electric actuator and be sure to input the correct

parameters. → 7. Setting Data Entry

Signal timing

For the single-pulse mode, check whether the pulse is input simultaneously with operational direction

Input the pulse after 15 ms or more (30 ms is recommended) has passed after the

direction is switched.

Incorrect pulse

input

Check that the number of input pulses recognized by the LECPA is the same as the number of pulses output from the controller setting kit or the teaching

box.

 2.5 Procedure (until

operating the electric

actuator)

Correct the calculation method for the

number of pulses and electric gear setting.

<When the number of pulses do not

match>

Correct the pulse counts, frequency, and output mode of the pulses output from the controller setting kit/teaching box to make them compatible with the LECPA parameter

settings and specifications.

Incorrect pulse

detection

Check for equipment which generates strong electrical noise around the

product.

Reduce the amount of noise generated from the surrounding equipment. Route the LECPA I/O cable separately from the noise source (surrounding equipment and their

cables).

The electric actuator does not move correctly.

Wiring fault

Is the wiring connected correctly?

Check if the wiring is connected correctly or if there is broken wire or short-circuit by referring to this Operation Manual. Correct the wiring and check that the input/output of each signal is correct. Separate the power supply for the CN1driver and the CN5 I/O signal power supply.

→ 4. External Wiring Diagram → 6.4 Parallel I/O Wiring Example

Inappropriate specifications

Check that the combination of the electric actuator and driver is

correct?

Check if the product number of the used electric actuator matches with the electric actuator which is applicable to the driver. → 3. Product Specifications

Signal timing

Check the timing of the signal from the PLC to the driver.

PLC processing delay and drver scan delay are generated. Please ensure an interval of 15ms (30 ms if possible) or more between

input signals, and maintain the signal state.

correctly.

Data writing failure

Is the data (step data or parameters) written

correctly?

One of the following actions occurred during data writing (while the power supply LED

(green) was on).

・Turn off the driver input power supply ・Disconnected/ connected cables.

Input correct data (step data, parameter) again and confirm operation.

→ 3.2 Parts description → 7. Setting Data Entry

Inappropriate basic parameters

Check that the parameter values are appropriate and the program is

correct.

Check the maximum speed, maximum acceleration speed, and maximum deceleration speed of the electric actuator again, and then be sure to enter the correct

parameters to check for correct operation.

In particular, check that optional setting 1 is

correct. → 7. Setting Data Entry

Incorrect pulse

input

Check that the number of input pulses recognized by the LECPA is the same as the number of pulses output from the controller setting kit or the teaching

box. → 2.5 Procedure (until

operating the electric

actuator)

Correct the calculation method for the

number of pulses and electric gear setting.

<When the number of pulses do not

match>

Correct the pulse counts, frequency, and output mode of the pulses output from the controller setting kit/teaching box to make them compatible with the LECPA parameter

settings and specifications.

Insufficient speed

Inappropriate basic parameters

Check that the parameter values are correct.

Check the max. speed and acceleration speed of the electric actuator and be sure

to input the correct parameters. → 7. Setting Data Entry

Inappropriate step data

Is the operation pattern trapezoidal?

In case of such operation, the actuator may start slowing down before it reaches the maximum speed. Modify the setting to make the moving distance longer or the acceleration larger. → 7. Setting Data Entry

Inappropriate specifications

Check that the combination of the electric actuator and driver is

correct?

Check if the electric actuator is operating within

the specification range.

Check if the product number of the used electric actuator matches with the electric actuator which is applicable to the driver. Check if the operating condition of the electric actuator is within the specification range. → 3. Product Specifications

Voltage drop

Check if there has been any temporary voltage drop in the power supply. (If there is a temporary voltage drop in the power supply, the EMG terminal of CN1 power connector will turn OFF so the actuator will stop. However, this stop will be released when the voltage recovers.)

There is a possibility of a momentary voltage drop because the capacity of the power supply is insufficient, or the power supply has inrush current restraining specification.

→ 3. Product Specifications

Incorrect pulse

input
