Example Calculation

of Current and Power

Consumption

Example for CJ1W-PA202 Power Supply Unit with the Following Modules Mounted

Name	Model	Quantity		Voltage system
				5 V	24 V
Coordinator	FQM1-CM001	1	0.47 A		---
Module
Motion Control	FQM1-MMP21	1	0.836	A	---
Module
	FQM1-MMA21	1	0.843 A		0.104 A
Current con-	Calculation		0.47 + 0.836 +		0.104 A
sumption			0.843
	Result		2.15 A (≤ 2.8 A)		0.104 ⋅ 24 V =
					2.5 W
Power con-	Calculation		2.15 ⋅ 5 V =		---
sumption			10.75	W
	Result		10.75	+ 2.5 = 13.75 W (≤ 14 W)

Note

The following table shows the Power Supply Units that can be connected for different numbers of Motion Control Modules.

Number of axes	Number of connected Motion Control		Power Supply Unit
	Modules
	FQM1-MMP21	FQM1-MMA21
2	1	0	CJ1W-PA202 (or
			CJ1W-PA205R)
	0	1
4	2	0
	1	1
	0	2	CJ1W-PA205R
6	3	0
	2	1
	1	2
	0	3
8	4	0
	3	1
	2	2
	1	3	Not possible
			(See note.)
	0	4

These combinations are not possible because the current consumption exceeds the capacity of the Power Supply Unit.
