Multi-network interface ac servo amplifier

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.
