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.

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.
