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%
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.
3.8.2 Wiring for Noise Control
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.
