7. SPECIAL ADJUSTMENT FUNCTIONS
(2) Requirements conditions of SEMI-F47 standard
Table 7.2 shows the permissible time of instantaneous power failure for instantaneous power failure of
SEMI-F47 standard.
(3) Calculation of tolerance against instantaneous power failure
Table 7.3 shows tolerance against instantaneous power failure when instantaneous power failure
voltage is "rated voltage × 50%" and instantaneous power failure time is 200 ms.
