Signal variations IMS-I

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)
