WARNING • As the equipment is heavy, make sure of its weight and gravity center position and disconnect the cables when carrying the equipment. Also, DO NOT carry the equipment with the slider. Otherwise, the slider will move and you will get injured.
Page 7
CAUTION • DO NOT place the equipment at a place where the ambient temperature exceeds 40°C, or where the temperature changes sharply, causing condensing, or where it is exposed to direct sunlight. Additionally, if the equipment is installed at a narrow place, the ambient temperature rises due to heat generation in the controller itself or external device, which will result in malfunction or mis-operation of the equipment.
■1.2 For your safe operation When you use the electric actuator KBK Series, be sure to take the measures in conformity to the following instruction: This machine is an industrial robot in conformance to the provisions of Paragraph 31of Article 36 of the Ordinance on Industrial Safety and Hygiene.

■1.2.2 Precautions for installation Observe the following instructions when installing a robot: (1) The robot shall be laid out to ensure the work space required for robot teaching, maintenance and inspection. (2) The robot controller, other controllers and stationary operation panel shall be installed outside the movable range and where the operator can watch the robot operations.
Page 10
(3) Measures to ensure the operation safety of the personnel working within the movable range Any one of the following measures or other measures on the equal or higher level shall be taken so that you can stop the robot operation immediately in the event of an error when working within the movable range: 1.

Chapter 4 Installing Actuator (Axis) ■4.1 Installing Actuator (Axis) This chapter describes the basic installation procedures for the axis and peripheral equipment. Installation shall comply with the instructions of this Chapter. If the installation procedure is incorrect, robot performance cannot be achieved.
Table are specified in the Actuator Instruction Manual. When you want to use a combination of axes, see the following Table for each an axis. [Robot type for KBX-T5/KBX-T7] When used as a slider traveling type axis (in normal use)
■4.3 Parameter values The parameters of this product are available in two types -- parameter 1 and parameter 2 -- depending on the frequency of use. The relationship between each parameter and the robot type is illustrated below: Setting the robot type allows the parameters on the circled portion on the left to be automatically changed. ■4.3.1 Values of parameter 1 for each robot type This parameter has a higher frequency of use.

■4.3.2 Values of parameter 2 for each robot type Straight axis (slider movable type) Automatic 600200 600210 600220 600230 Robot type setting Parameter (Lead 6) (Lead 12) (Lead 6) (Lead 12) Axis display 00.05 00.05 00.05 00.05 In position data value 20000 20000 20000...
Chapter 5 Precautions for Use ■5.1 Servo gain setting In the actuator, in order to facilitate the parameter setting work of the controller, the initial parameters for operating the component arm are automatically set by setting the "robot type" (6 digit number) determined for each model to the controller.
Page 24
(2) Speed gain (V) ● When the value is reduced ・ If it is made too small, an error such as "overflow error" may occur during operation (especially when accelerating) and operation may not be possible. ・ The positioning and holding force of the slider is reduced. (Rigidity decreases) ●...
Page 25
■5.1.2 About adjustment of servo gain When adjusting the servo gain, refer to the contents described in ■ 5.1.1 "Servo gain setting value and operating condition" and set according to the following description. (1) Speed gain setting The initial value of speed gain usually does not need to be changed. If it is changed, please set as follows.
Page 26
● Abnormalities such as vibration and abnormal noise may occur due to resonance, so check the operation from the low speed range used for return to origin operation and "JOG" operation to the high speed range used for continuous operation. ●...
Chapter 6 Maintenance ■6.1 Precautions for inspection and maintenance work (1) Precautions for inspection and maintenance work observe the following instructions at the time of inspection and maintenance: 1. The robot shall be inspected and maintained by the personnel having a sufficient level of skill and experience. If such personnel are not available, contact the manufacturer and request implementation of the relevant work or education of the person in charge.
■6.2 Inspection before starting the work (1) Before starting your work with the robot, make sure of the following: 1. Brake device function 2. Emergency stop device function 3. Contact preventive equipment and robot interlock function 4. Related devices/robot interlocking function 5.
■6.4 Adjusting Home Position Adjust the home position in the following manner. (1) Turn the power off. (2) Loosen and remove the two (2) low-head plus screws from the top side of the motor block. Fig. 6.4–1 (3) Remove the stainless sheet and loosen one (1) hexagon socket head cap screw (M2.5) of the coupling connecting the motor and ball screw.
Page 30
(4) Temporarily connect the actuator and controller, connect the teach pendant with the controller, then turn the power on. For how to connect, see Para. 2.5.4 of the instruction manual (basic) provided separately. (5) Set the servo gain values (position and speed) of Parameter 1 to zero (0). For the setting procedures, see Para. 13.3.3,13.3.4 of the instruction manual (basic).
■6.5 Changing Home Position (1) Specify "0" for the motor revolving direction of Parameter 2. (2) Adjust the home position. As in Para. 5.4 above, the position "B" mm away from the end block should be the home point. (See Fig. 6.5–1.) Fig.
Page 32
Before tightening the coupling clamp screw, be sure to turn off the controller power. CAUTION DO NOT shift the motor shaft and coupling from the stopped positions The home position differs between the KBX-T5 and KBX-T7 actuators. (See Fig. 6.6–4.) Fig. 6.6–4 Type of axis...
■6.7 Replacing Stainless Sheet To replace the stainless sheet, observe the following procedures. Take careful precautions not to cut your hand by the stainless sheet. CAUTION (1) Remove the four (4) screws securing the stainless sheet, using a screwdriver, and remove the plate. Fig.
■6.8 Greasing Greasing procedures • Ball screw and linear guide 1. Turn off the drive power. 2. Remove the screws (4 places) fixing the stainless sheet. 3. Greasing according to the table and figure shown below. Type of grease Inspection and Greasing position Volume of grease (manufacturer)
■6.9 Replacement of ball screw If the replacement of ball screw needs to be replaced, contact our sales office closest to your company. It must not be replaced by the customer. This replacement is performed for each axis. It should be noted that this replacement cannot be made inside the device or in the combined state.
Accordingly, you are recommended to keep spare parts on hand. Part name Remarks For KBX-T5 Stainless sheet For KBX-T7 (Differs with the stroke.)
