Note 1) Power capacity at rated load
2) Operating characteristics (25°C): 2 seconds or more for 200%, 0.01 second or more for
700%
3) A fast-operating fuse cannot be used because the SERVOPACK power supply is a ca-
pacitor input type. A fast-operating fuse may blow out when the power is turned ON.
3.8.2 Wiring for Noise Control
J Example of Wiring for Noise Control
This SERVOPACK uses high-speed switching elements in the main circuit. It may re-
ceive “switching noise” from these high-speed switching elements if wiring or grounding
around the SERVOPACK is not appropriate. To prevent this, always wire and ground the
SERVOPACK correctly.
This SERVOPACK has a built-in microprocessor (CPU). To protect the microprocessor
from external noise, install a noise filter in place.
