The reference mark search does not need to be performed for serial
encoders with EnDat interface, because the axes are automatically
homed.

Explanation
Dummy load to avoid reflections
Settings: ON or OFF
Default value: ON
Monitoring of signal errors
Settings:
Off: Error monitoring not active
Amplitude: Error monitoring of the signal amplitude
Frequency: Error monitoring of the signal frequency
Frequency & amplitude: Error monitoring of both signal
amplitude and signal frequency
Default value: Frequency & amplitude
A warning or error message is displayed if one of the
limit values for error monitoring is exceeded.
The limit values depend on the signal of the connected encoder:
Signal: 1 Vpp, setting: Amplitude
Warning with voltage ≤ 0.45 V
Error message with voltage ≤ 0.18 V or ≥ 1.34 V
Signal: 1 Vpp, setting: Frequency
Error message with frequency ≥ 400 kHz
Signal: 11 µApp, setting: Amplitude
Warning with current ≤ 5.76 µA
Error message with current ≤ 2.32 µA or ≥ 17 .27 µA
Signal: 11 µApp, setting: Frequency
Error message with frequency ≥ 150 kHz
Signal detection during axis movement
Settings:
Positive: The direction of traverse corresponds to the
counting direction of the encoder
Negative: The direction of traverse does not correspond to
the counting direction of the encoder
Default value: Positive
