Design and Installation
j Selecting Components
This section explains the standards for selecting the required components for improving noise resis-
tance. When selecting components, it is necessary to understand characteristics such as the capacity,
performance, applicable range, and so on. For details regarding any of the recommended products
listed in the tables below, contact their respective makers.
When selecting no-fuse breakers, take into consideration the maximum output current and the inrush
current. The momentary maximum output for a servo system is approximately three times that of the
rated output, and a maximum output of three seconds can be executed. Therefore, select no-fuse
breakers with an operating time of at least five seconds at 300% of the rated maximum output. General-
purpose and low-speed no-fuse breakers are generally suitable. Refer to the table in 2-2-3 W iring T er-
minal Blocks for the power supply input currents for each motor, and then add the current consumption
for the number of shafts, other controllers, etc., to make the selection.
The Position Driver inrush current flows at a maximum of 50 A for 20 ms when 200 V is input. With low-
speed no-fuse breakers, a inrush current 7 to 8 times the rated current flows for 0.1 second. When mak-
ing the selection, take into consideration the entire inrush current for the system.
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 panel whenever possible.
Use twisted-pair cables for the power supply cables whenever possible, or bind the cables.
Separate power supply cables and signal cables when wiring.
