  • Page 32: Parameter Setting Method

    3.4 Parameter setting method Initial setting for the basic parameters Refer to the controller’s (LEC series) operation manual for detail. As the “basic parameter” is unique data of each actuator, if an actuator other than the “electric actuator / slider type” is used, refer to the operation manual of each actuator and the controller’s (LEC series) operation manual for the basic parameter.
  • Page 33 Initial setting for the ORIG parameters Refer to the controller’s (LEC series) operation manual for detail. As the “ORIG parameter” is unique data of each actuator, if an actuator other than the “electric actuator / slider type” is used, refer to the operation manual of each actuator and the controller’s (LEC series) operation manual for the “ORIG parameters”.
  • Page 34 ＜Origin offset＞ The origin offset means the value of the origin. (“Origin offset”=The display value of origin) When the parameter “Origin offset” is changed, the value of “Stroke(+)”, “Stroke(-)” of basic parameter should be checked again. When the parameter “Origin offset” is changed, the display value of origin is changed. The step data should be checked again.

    4. Wiring of cables / Common precautions Warning Adjusting, mounting or wiring change should never be done before disconnecting the power supply to the product. Electrical shock, malfunction and damage can result. Do not disassemble the cables. Use only specified cables. Do not connect or disconnect the wires, cables and connectors when the power is turned on.

    5. Electric actuators / Common precautions 5.1 Design and selection Warning 1. Be sure to read the operation manual (this manual and the one for the controller: LEC series). Handling or usage/operation other than that specified in the Operation Manual may lead to breakage and operation failure of the product.

  • Page 37: Mounting

    When conformity to UL is required,the electric actuator and controller should be used with a UL1310 Class2 power supply. 5.2 Mounting Warning 1. Install and operate the product only after reading the Operation Manual carefully and understanding its contents. Keep the manual in a safe place for future reference. 2.

  • Page 38: Operating Environment

    Do not apply impact/collision/resistance for mover of actuator in operation. It will cause decrease of product’s life, damage to product, and so on. Caution Keep the controller and product combined as delivered for use. The product is set in parameters for shipment. If it is combined with a different product parameter, failure can result.

  • Page 39: Maintenance

    6. Grease oil can be decreased due to external environment and operating conditions and it deteriorates lubrication performance to shorten the life of the product. [Storage] Warning 1. Do not store the product in a place in direct contact with rain or water drops or is exposed to harmful gas or liquid.

  • Page 40: Electric Actuators / Slider Type Common Precautions

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