Description
- Analog output signals (Sinus 1Vss)
- Digital output signals (TTL 1µ, 5µ, 10µ)
Technical data
Analog output signals, sinusoidal signals 1 Vpp
(option I1)
Incremental signals
The sinusoidal incremental signals A and B are phase offset by 90° to each other and have a typical signal amplitude of 1 Vpp.
Signal amplitude: A, B = 1 Vpp (±0.1 V)
The illustrated output signal sequence (B phase-lagged to A) applies to scanner motions in the positive counting direction (see graph).
Reference mark signal
The differential reference mark signal RI has an amplitude of about -0.7 V when inactive (low). In an active state (high) the amplitude is +0.7 V.

Digital output signals, square-wave output signals TTL through integrated interpolation unit
(options I2, I3, I4)
Incremental signals
The digital incremental signals A and B comply with the EIA/TIA-422-A standard. They are phase offset by 90° and have the following signal levels:
Uhigh > 2 V
Ulow < -2 V
The switching response times are ≤ 100 ns at a capacitive load of ≤ 1000 pF.
Reference mark signal
The differential reference mark signal RI has the same electrical characteristics as the incremental signals.
The stated amplitude values apply for operation with a terminating resistor Z0 = 120 Ω. (See interface circuitry)
The graph shows: A, B and full differential RI for motion in the positive counting direction.
