2. Product Outline

2.1 Product features

The followings are the main functions of this controller:

●

Electric actuator control

Positioning operation and operation at a specific speed for the electric actuator are possible by controlling the Step motor (servo 24 VDC).

●

Operation and settings are available with the controller.

Settings can be altered and operation can be run from the controller. Adjustments of the position, speed, acceleration and test runs are available without the teaching box, PC, and PLC.

●

Power supply separation input

The power input is separated into two systems of motor power supply and control power supply, and when the control power supply is on while the power supply is off, the parallel I/O control is not lost without losing the position information of the encoder is possible.

●

Positioning of 12 intermediate points and both stroke end points are possible.

According to the combination of parallel I/O inputs, it is possible to perform positioning operation of 12 points (position numbers 3 to 14 (E)) and positioning operation to the stroke end point (two points on the end side and the motor side). In addition, it is possible to set the speed and the acceleration by the switch for each driving direction.

●

Stroke study

By the stroke study, LEC 6 controller recognizes the possible moving area and registers both stroke end points automatically. Just after the controller is delivered and after adjusting the stopper of the electric actuator, the stroke study must be performed.

Caution

When the power is turned on immediately after purchasing the controller, the ALM LED of the

controller blinks in red because the stroke learning has not been performed yet. When stroke learning is executed, the ALM LED goes out.

· When executing stroke learning, the registration position of all intermediate positions will be changed

so be sure to re-register all intermediate positions (position numbers 3 to 14 (E)).

●

Automatic sequence function of the return to origin position

When power is applied to the LECP2 controller stroke study is performed and return to origin to the commanded side is possible when the first command of driving to stroke end is executed. (A dedicated signal for return to origin is not required.)

●

Alarm detection function

Abnormal conditions are self-detected. Alarms are displayed by LED on the controller and abnormal conditions are output to the parallel I/O terminal.

Caution

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.

(2) 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.

Power supply cable Controller input power supply

Switch for forced unlocking

Caution

If the electric actuator is a non-lock type, it is not necessary to wire the BK RLS terminal. Do not supply power to the BK RLS (lock release) during normal operation. The 24 VDC supply to the BK RLS (lock release) is only required for the adjustment and the recovery in the emergency.

- STOP command (CN4 14pin STOP) is turned ON and Servo is turned OFF.

- When the control power supply (C24V) is shut off.

(3) Stop the power supply for the motor

If it is necessary to shut off the power supply for the motor from outside, connect the relay between the input power supply for the controller 24 VDC and the power supply plug for the controller M24V. (Refer to the wiring diagram in the next page.) The motor power supply should be shut off after the STOP command (CN4 14pin STOP) is turned ON. Refer to “6.3 Details of parallel input / output signal and cable” for the STOP command

Warning

- Do not perform a return to origin position when the the power supply for the motor (M24V) is off. The controller cannot recognize the correct origin if a return to origin instruction is made with the motor drive power (M24V) disconnected.

- If the M24V is off during electric actuator operation, there will be an additional delay experienced before it stops (the stop distance will be extended) due to inertia of the work piece or regenerated energy. When the M24V is turned off, and the STOP command is turned ON (CN4 14pin STOP) simultaneously the time to stop can be shortened.

- If the motor drive power is off during a vertical stop, the table may drop due to lock response.

- BK RLS is internally connected to the M24V inside the controller, so do not apply 24 VDC to the BK RLS terminal when the M24V is off.

8. Operations

8.1 Return to origin

Origin return is necessary after turning on the power supply in this controller. By recognizing the stroke end by return to the origin, positioning operation of the electric actuator becomes possible.

(1) Return to origin operation

When power is supplied to the controller, the first command to move toward the stroke end is recognized as the return to origin command. Controller speed and acceleration setting switches are ignored. The slider of the electric actuator moves toward the specified direction with the speed and acceleration of the electric actuator itself. After that, the electric actuator keeps pushing the stroke end. When the electric actuator keeps pushing the stroke end for several seconds, the controller recognizes the current position as the stroke end and the return to origin is completed. The stop position in all position numbers doesn't change regardless of the direction of the return to origin. The speed of the return to origin depends on the electric actuator. Refer to “10. Initial setting value of electric actuator (LEM series)” for the default setting of the return to origin.

(2) How to command the return to origin

Only when the following two conditions are satisfied, it is possible to command the return to origin.

· Stroke study has been completed before.

· It must be immediately after turning on the controller.

Return to origin command is an operation command to the first stroke end after turning on the power supply. Return to origin command method includes manual mode and auto mode.

Manual mode:

1) Supply the power supply to the controller.

2) Switch the position switch (h) to “1” or “2”, and push Set button (g). During return to origin, 7-segment LED (f) displays “F” with flashing.

Switch the position switch”1”： Return to origin by end side movement. Switch the position switch”2”： Return to origin by motor side movement.

3） When the return to origin is completed, the display of 7-segment LED (f) changes from flashing

state to solid light state.

Auto mode：

1) Supply the power supply to the controller.

2) Turn on IN0 or IN1 input in CN4 parallel I/O. During return to origin, 7-segment LED (f) displays “F” with flashing.

Turn on IN0：Return to origin by end side movement Turn on IN1：Return to origin by motor side movement.

3) When the return to origin is completed, OUT0 or OUT1 output turns on.

When return to origin with IN0 ON：OUT0 output turns on. OUT1 to 3 output turns off

When return to origin with IN1 ON：OUT1 output turns on. OUT0, OUT2 to 3 output turns off. When the power supply is supplied to controller, only “Stroke study” and “The command to stroke end (The return to origin)” is valid in the first command to drive. When an operation toward the intermediation position is commanded immediately after power is supplied, return to origin is invalid. When a stroke study is performed, return to origin is performed simultaneously. After the stroke study, the command to move toward the stroke end is not recognized as return to origin command. Positioning operation will be performed.

8.3 Jog operation / inching operation

Jog operation and Inching operation can be operated in manual mode.

(1) Jog operation

The electric actuator moves to the specified direction while the button is pressed. It stops when the button is released. This operation is available before return to origin is performed.

Procedure

1) Switch the controller mode switch (e) to manual mode (M).

2) When the Forward button (i) and Reverse button (i) are pressed simultaneously, the inching operation starts. When the buttons are pressed for longer than 1 second in that state, Jog operation starts.

When this button is released, the product stops operating.

(2) Inching operation

When the button is pressed once, the electric actuator moves for a specified distance in the specified direction and stops.The operation is available before return to origin is performed.

Procedure

1) Switch the controller mode switch (e) to manual mode.

2) Press the Forward button (i) or Reverse button (j). The electric actuator will perform the inching

operation in the specified direction and stops.

Caution

●The driven distance and the speed when Inching, and the speed when Jog are different in each electric actuator. Refer to “10. Initial setting value of electric actuator (LEM series)” for details.

●The driven distance and the speed when Inching, and the speed when Jog can be change by the parameter. Refer to “7.3 Setting parameters” for details.

8.4 Servo ON

Servo ON signal is not assigned to the parallel I/O of this controller. When the power supply is supplied

to controller, “Servo on” is automatically commanded in the controller. At this time, when the alarm is

not generated, the electric actuator becomes the servo on state after a few seconds. (Just after the motor power is applied, it may take up to 10 seconds for ALARM output depending on the electric actuator position.) When the electric actuator becomes the servo on state normally, Power LED (a) changes from flashing state to no-flashing state.

The table below shows conditions for becoming servo off state.

8.5 Response time for the controller input signal

Response delay due to the controller input signal contains following factors.

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

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 15ms (recommendation is 30 ms), because PLC processing delays and controller scanning delays can occur. Time the input signal conditions according to the response output signals.

When one command is made by inputting several I/O simultaneously, the time difference between signals has to be 3 ms or less. If the time difference is longer than 3 ms, it is recognized as another signal and starts the operation. For example, when IN0 and IN1 are commanded to turn ON (position number 3) simultaneously and the time difference between them is large, only the first command is recognized (Only IN0 input is recognized in the following example).

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 drops 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, wearing of the lock sliding surface will be accelerated, causing reduction in the holding force and the life of the locking mechanism.

(8) Do not supply 24 VDC power supply constantly 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 work pieces may be dropped at stop (EMG). / Refer to the operation manual of LEC (controller) for details of wiring.

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 electric 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 suppression type. → 3. Product Specifications
