Issue:
MTBF data on the ATV212 drives

Product Line:
Altivar ATV212

Environment:
All

Cause:
Needs to know if we have any MTBF data on the ATV212 drives.

Resolution:
See the attached document.  Please note that this data does not include the heat sink cooling fan.

MTTF ATV212

This document gives the mean time to failure (MTTF) values of Altivar 212 variable speed drives.

Altivar 212 MTTF values are based on IEC 62380.
The fan is an aging part to replace in maintenance. Hence the fan is not taken into account in these MTTF values.

Voltage	Kw	MTTF values
Three 240V (M3X)	0.75	560000
	1.5	560000
	2.2	560000
	3	540000
	3.7	540000
	5.5	540000
	7.5	540000
	11	500000
	15	500000
	18.5	500000
	22	430000
	30	350000
Three 500V (N4)	0.75	560000
	1.5	560000
	2.2	560000
	3	540000
	3.7	540000
	5.5	540000
	7.5	540000
	11	540000
	15	500000
	18.5	500000
	22	400000
	30	400000

MTTF= MUT1= Mean Time To (first) Failure
MUT= Mean of MUTI= Mean Up Time
MDT= Mean of MDTI= Mean Down Time
MTBF= MUT+MDT= Mean Time between Failures
