User manual IAI ERC FORTH EDITION

[. . . ] ERC Actuator with Integrated Controller Operation Manual Forth Edition CAUTION 2. Basic Parameter Settings When the power is input for the first time, at least the two parameters specified below must be set in accordance with the intended application. If these parameters are not set properly, the ERC will not function correctly. So, pay due attention to ensure the parameters are set properly. [. . . ] LED10 illuminates when this signal turns ON. Remarks TB3 Output common (Out-COM) 24 [V] (Note 1) The input common and output common become 24 [V] and 0 [V], respectively, in the NPN specification. 57 [1] Internal connection diagram RCB-TU-PIO-A/B Actuator end Host system end Connector Nonpolar input photocoupler Input common 6 circuits 6 circuits Fusing chip resistor 4 circuits 4 circuits Output common 58 [2] PCB-TU-PIO-AP/BP Actuator end Host system end Connector Nonpolar input photocoupler Input common 6 circuits 6 circuits Fusing chip resistor 4 circuits 4 circuits Output common 59 I/O interface specifications Input Specifications Specification item Number of input points Input voltage Input current Allowable leak current Operating voltage 6 points ± 24VDC ± 10% 7 mA/point (bipolar) 1 mA/point (approx. 2 mA at normal temperature) ON voltage: 16 V min.

Data Entry <Basics> This actuator doesn't use command words, so there is no need to create a program. All you need is to enter the target position in the position-data table, and the actuator will move to the specified position. Position data consists of number (No. ), target position (Position), speed (Speed), acceleration/deceleration (ACC), push (Push), positioning band (Pos. band), and acceleration only MAX (ACC MAX). The description in parentheses is as displayed on the teaching pendant. The target position can be specified in two different modes: by absolute coordinate specification (absolute mode) in which the distance from the home is entered, or by relative coordinate specification (incremental mode) in which the incremental movement from the current position is entered. Position-data table No. 0 1 2 ~ ~ Position Note 0 30 10 Speed 100 100 100 = Acceleration/ deceleration 0. 3 0. 3 0. 3 Push 0 0 0 Positioning band 0. 1 0. 1 0. 1 Acceleration only MAX 0 0 0 ~ ~ 15 100 100 0. 3 0 0. 1 0 When data is entered in the position column of the position-data table, the default values will be automatically entered in the remaining columns. To change a default value, change the corresponding parameters starting with "Default. " The default values vary depending on the actuator type. This indicates that the incremental mode is active. (This symbol is displayed only on the teaching pendant. Separate columns for incremental specification are provided in the PC software. ) Note: Enter position data first. Any attempt to enter other data before position data will be rejected. You can enter position data containing two decimal places. However, the controller only recognizes position data as a multiple of its minimum resolution. The minimum resolution of the controller varies depending on the actuator lead. For the above reason, the second decimal place in the entered position data may be rewritten in accordance with the actuator lead. Example: Entered value Stored value 50. 01 50. 03 61 5. 1 (1) No. Description of Position-Data Table · Indicate the position data number. To enter an incremental movement, press the minus key in this column. On the teaching pendant, a "=" will be displayed between the number and position columns. [. . . ] Spread the grease evenly on the opposite side in the same manner. [3] Move the slider back and forth several times by hand. [5] Use a waste cloth, etc. , to wipe off excess grease from the slider. 118 10. 7 Greasing the Ball Screw (Slider Type) (1) Applicable grease The following special grease is applied to the ball screw prior to shipment: Kyodo Yushi Multemp LRL3 This grease generates less heat and has other excellent properties suitable for ball screws. For equivalent grease products, refer to the brands specified for the guide (lithium grease). Note to the user: Never use fluorine grease. If fluorine grease is mixed with lithium grease, the grease function will drop and it causes damage to the mechanism. (2) Greasing method After cleaning the ball screw, apply grease and stroke the slider to let the grease spread evenly. [. . . ]
