13-2 Servo Drive Lifetime
• The lifetime of Servo Drive depends on application conditions. When the ambient temperature is
40°C and the average output is 70% of the rated output, the design life expectancy is ten years.
• The use of the Servo Drive in a hot environment shortens its lifetime. We recommend that the ambi-
ent temperature and the power supply ON time be reduced as much as possible to lengthen the life-
time of the Servo Drive.
• The lifetimes for the different parts of Servo Drive are given below.
