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.
Name Lifetime
Inrush current prevention relay Approx. 36,500 operations (lifetime depends on application conditions.)
Brake interlock output relay Approx. 36,500 operations (lifetime depends on application conditions.)
