only channel A:
Input for two sine-wave, shifted by 90° differential signals with U

=1 V, maxi-
mum 200 kHz.
single-ended (e.g. Cos+ against GND):
Constant component 2.5 V ±0.5 V
differential (e.g. Cos+ against Cos-):
Constant component 0 V ±0.1 V
Signal level U
PP
=0.6 V…1.2 V
Channel A and b:
Input for square-wave incremental signals according to RS485 maximum
300 kHz
only channel b:
Incremental encoder simulation: Position changes of channel A are output to
channel B with two 90° shifted RS485 signals.
5, 6
N+/-
only channel A:
Input zero signal once per revolution.
Differential signal level (N+ - N-):
• higher 50 mV: zero signal is active
• from50mVto-50mV:undefined
• lower -50 mV: zero signal is inactive
Signal length 330°…360° of the signal length of the incremental signals.
Channel A and b:
Input zero signal or data RS485.
Zero signal is 1-active, if signals A and B are also 1-active.
only channel b:
Output zero signal RS485.
Zero signal is 1-active, if signals A and B are also 1-active.
Is output, if the position on channel A is 0°.
