2.11 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in
performance when subjected to the radio frequency (RF) environments defined in Table 4.
2.12 AFR and Warranty
The product will achieve an Annualized Failure Rate (AFR) of <1% when operated in an environment of ambient air
temperatures of 25°C. Operation at temperatures outside the specifications shown in Environmental
specifications on page 18 may increase the product AFR. AFR is a population statistics that is not relevant to
individual units.
AFR specifications are based on the following assumptions for consumer electronics environments:
8760 power-on-hours per year
10,000 average motor start/stop cycles per year
Operations at nominal voltages
Temperatures outside the specifications in Environmental specifications on page 18 may reduce the product
reliability.
Normal I/O duty cycle for consumer electronics environments. Operation at excessive I/O duty cycle may
degrade product reliability.
The consumer electronics environment of power-on-hours, temperature, and I/O duty cycle affect the product
AFR.The AFR will be degraded if used in an enterprise application.
