Action against high-frequency interference
High-frequency interference can be caused by out-of-phase switching operations. If such interference
occurs and results in sporadic failure, we recommend taking the following action to suppress interfer-
ence:
■
Provide inductive loads with RC combinations as per manufacturer's specifications.
■
Route bus lines separately from power lines.
■
Increase the distance from sources of interference.
■
Check the shield connection to the central earthing point (CEP) in the control cabinet.
■
Suppress HF interference using hinged-shell ferrite rings.
System malfunctions
Attention
■
An alarm is triggered when the CAN bus line is interrupted.
