Current Consumption for 24-V Systems
Example Calculation
of Current and Power
Consumption
Example for CJ1W-PA202 Power Supply Unit with the Following Modules
Mounted
Combining Power
Supply Units and
Motion Control
Modules
The following table shows the Power Supply Units that can be connected for
different numbers of Motion Control Modules.
Note
These combinations are not possible because the current consumption
exceeds the capacity of the Power Supply Unit.
