| Interference prevention function | Incorporated- Series connection: 3 sets max. (Total 128 beam channels). (However, SF2B-Ax allows up to a total of 96 beam channels when two sets are connected, and up to 64 beam channels when three sets are connected). (Note 1)SF2B-Hx and SF2B-Ax can be used together. (Note 2)[When using SF2B-CB05-B (optical synchronization):- Series connection: 3 sets max. (Total 128 beam channels). (However, SF2B-Ax allows up to a total of 96 beam channels when two sets are connected, and up to 64 beam channels when three sets are connected). (Note 1)- Parallel connection: 2 sets max.- Series and parallel mixed connection: Series connection of 3 sets max. and parallel connection of 2 sets max. are simultaneously possible.SF2B-Hx and SF2B-Ax can be used together. (Note 2)](Note 1) The SF2B-H8-x and SF2B-A4-x cannot be connected in series.(Note 2) When making series connection mixing SF2B-Hx and SF2B-Ax, calculate by doubling the number of optical axes only for SF2B-Ax, and make the total number of optical axes fall below 128 axes.(e.g.) When making series connection with SF2B-H36 and SF2B-A44, the total number of optical axes will be 124 axes. The number of optical axes for SF2B-H36 + (number of optical axes for SF2B-A44 × 2) = total number of optical axes. 36 optical axes + (44 optical axes × 2) = 124 optical axes. |
