Safety sub-function
Safety performance
*1 A test pulse is a signal which instantaneously turns off a signal to the servo amplifier at a constant period for external circuits to perform
self-diagnosis.
*2 The performance of special proof tests within the mission time of the product is regarded as not necessary. For example, on IEC 61800-
5-2:2016, the diagnostic interval is suggested as at least one test per three months for SIL3, Category 3 PL e.
