1) Power capacity at rated load
2) Operating characteristics (25°C): 2 seconds or more for 200%, 0.01 second or more for
700%
When control circuit breaker and main circuit breaker are used separately, be aware of
in-rush current (30 to 40A, for 5ms or less) flows at control power ON.
3) A fast-operating fuse cannot be used because the Servopack power supply is a capaci-
tor input type. A fast-operating fuse may blow out when the power is turned ON.
This noise control do not conform to the EMC instructions.
To adapt DR2 Servopack to EMC instructions, refer to 7 Measures to
Satisfy the Requirements of EMC Instructions.
1) Example of Wiring for Noise Control
a) 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 ground-
ing around the Servopack is not appropriate. To prevent this, always wire and ground
the Servopack correctly.
b) This Servopack has a built-in microprocessor (CPU). To protect the microprocessor
from external noise, install a noise filter in place.
