8.4 Specifications of 11µApp Interface Board

Signal amplification (Ie1, Ie2, Ie0): 300

Input amplifier:

Maximum signal current: Ie0, Ie1, Ie2: 66 µApp

Maximum frequency at encoder input:

-3 dB: approx. 300 kHz

Note:

The maximum input frequency only stands for the cutoff frequency of current/voltage converter in PWM 8

(signal source: frequency generator). In real operation with encoders the frequency highly depends on the

photocells and their capacitance, as well as on the cable lengths.

Measure current/voltage:

Measuring range current: 0 - 500 mA

Measuring range voltage: 0 - 10 V

Tolerance: ± 3 %

Measure amplitudes:

Measuring range: 2 µApp - 33.3 µApp (0.6 - 10 Vpp)

Measuring frequency: 10 Hz - 50 kHz

Tolerance:

without adjustment via software: ± 5 %

with adjustment via software: ± 3 %

Fault detection signal: Ie1 and Ie2 < 4 µApp

Encoder output:

Output signal: like input signal without U

8.5 Specifications of 1Vpp Interface Board

Input amplifier:

Maximum signal voltage: ± 5 Vpp

Maximum frequency at encoder input:

for encoder voltage on interface board: approx. 500 kHz

for signals on BNC sockets (- 3dB): approx. 1 MHz

Note:

Input frequencies over 1 MHz are possible; however, the tolerance of the PHA/TV display can no longer be

guaranteed!

The maximum input frequency only stands for the cutoff frequency of the voltage input of PWM 8 (signal

source: frequency generator). In real operation with encoders the frequency highly depends on the encoder

and on the cable lengths.

Measure current/voltage

Measuring range current: 0 - 500 mA

Measuring range voltage: 0 - 10 V
