Page 3: System Description
Alarm output The REF interface asserts the alarm output (E) for the following conditions:- The RGH25F encoder system consists of a common readhead in standard or UHV compatible form, Incremental signal level below 20% coupled to the interface, which gives accurate, industry standard outputs. There are 10 versions of the Incremental signal level above 135% REF interface, offering digital resolutions of 5 µm to 5 nm, and an analogue version giving 1 Vpp output. -

2.25 Vpp @ 100% signal amplitude centred on 1.65 V not vacuum compatible. The RGH25F series readheads have been designed to the relevant EMC standards (BS EN 61000 BS EN 55011), but must be correctly integrated to achieve EMC compliance. In particular, attention to shielding and earthing arrangements is essential. - Page 8 0400 - 50 nm 1000 - 20 nm 2000 - 10 nm 4000 - 5 nm Interface series * Binary interpolation factors from x4 to x4096 also available NOTE: Not all combinations are valid.
