Eletrial data - b maXX ® BM3400 D.6T
D.6.2 Inremental eno der emulation (option)
There are two square wave pulse sequences +A and +B (phase shifted by 90°) and its inverted pulse sequences
−A and −B as well as zero pulse +Z ERO with the inverted signal −Z ERO. These signals are provided sepa-
rated via optocoupler and have RS422 level. The pow er supply for the optocoupler and the RS422-line driver
occurs via the encoder input of the target device, which is to be connected.
