[. . . ] I553-E1-01 Servomotors/Servo Drivers @ MODELS R7M-Z@ (Servomotors) @ R7D-ZP@ (Servo Drivers) SMARTSTEP Junior USER´S MANUAL Thank you for choosing this SMARTSTEP Junior product. This manual provides information on installation, wiring, and switch setting for the SMARTSTEP Junior Servomotors and Servo Drivers. For information about troubleshooting, refer to the SMARTSTEP Junior User's Manual (Cat. I553). Intended Audiences This manual is intended for the following personnel, who must also have knowledge of electrical systems (an electrical engineer or the equivalent). [. . . ] Metal duct or conduit Noise filter Surge absorber Noise filter Brake power supply Radio noise filter Device with built-in motor Radio noise filter R7D-Z@ R7D-Z@ Contactor AC power supply Metal duct or conduit Radio noise filter Class ground (to 100 or less) 2 m max. Clamp filter Clamp filter Clamp Clamp filter Ground plate Controller power supply Clamp Clamp filter Controller Note 1. 2. Make 1. 5 turns for the ferrite core's cable winding. Peel the insulation off the cable at the clamp, and directly connect the shield to the metal plate. · Ground the motor's frame to the machine ground when the motor is on a movable shaft. · Use a grounding plate for the frame ground for each Unit, as shown in the above diagrams, and ground to a single point. · Use ground lines with a minimum thickness of 3. 5 mm , and arrange the wiring so that the ground lines are as short as possible. · No-fuse breakers, surge absorbers, and noise filters (NF) should be positioned near the input terminal block (ground plate), and I/O lines should be isolated and wired using the shortest distance possible. · If no-fuse breakers are installed at the top and the power supply line is wired from the lower duct, use metal tubes for wiring and make sure that there is adequate distance between the input lines and the internal wiring. If input and output lines are wired together, noise resistance will decrease. · Wire the noise filter as shown at the left in the following illustration. The noise filter should be installed at the entrance to the control box whenever possible. Correct: Separate input and output AC input AC output 2 Wrong: Noise not filtered effectively AC input Ground Ground AC output · Use twisted-pair cables for the power supply cables whenever possible, or bind the cables. 4-12 4-2 Wiring 4-2-5 Conforming to EMC Directives Correct: Properly twisted Driver Correct: Cables are bound. Driver Binding · Separate power supply cables and signal cables when wiring. Control Panel Construction Openings in the control panel, such as holes for cables, operating panel mounting holes, and gaps around the door, may allow electromagnetic waves into the panel. To prevent this from occurring, observe the recommendations described below when designing or selecting a control panel. Case Structure · Use a metal control panel with welded joints at the top, bottom, and sides so that the surfaces will be electrically conductive. · During assembly, strip the paint off of joint areas (or mask them during painting), to make them electrically conductive. · If gaps appear in the control box case when screws are tightened, make adjustments to prevent this from occurring. · Do not leave any conductive part unconnected. · Ground all Units within the case to the case itself. Door Structure · Use a door that is made of metal. · Use a water-draining structure where the door and case fit together, and leave no gaps. (Refer to the diagrams below. ) · Use a conductive gasket between the door and the case, as shown in the diagrams below. (Refer to the diagrams below. ) Strip the paint off of the sections of the door and case that will be in contact with the conductive gasket (or mask them during painting), so that they will be electrically conductive. · Gaps may open between case panels when screws are tightened. Be sure that no gaps appear when tightening down screws. 4-13 4-2 Wiring 4-2-5 Conforming to EMC Directives Case Door Oil-resistant gasket Control panel Conductive gasket Cross-sectional view of A­B Oil-resistant gasket Conductive gasket Door (interior view) Selecting Connection Components This section explains the criteria for selecting the connection components required to improve noise resistance. [. . . ] Use a dedicated power supply as the 24-V DC power supply for command pulse signals. The diode recommended for surge absorption is the ERB44-02 (Fuji Electric). Do not use the 24-VDC control power supply for the brake power supply (24 VDC).
