Connection Cable:
Twisted pair with complete screening,
screening grounded at both ends.
Max. cable length 20m.
Note:
The superordinate control must be able to process the encoder simulation high output frequencies.
Example: f = 3000 min

· 2048 pulses = 102 kHz. If necessary, an industry standard external
frequency divider can be used.
x = A, B or R
Additional Input for incremental encoders
Servocontrollers which are equipped to evaluate signals from optical encoders (Version code
D2) also have an additional function which can be used in future by specific software modules.
In this equipment the X9 connector can also be used as an input for an additional incremental
encoder with square-wave output signals. Encoder simulation and incremental encoder input
both use non-inverted and inverted signals (e.g. +1A=LOW
→
-1A=HIGH).
Evaluation of encoder simulation signals
Line receiver MC3486 is suitable for evaluating differential signals. The line should be terminated
with a 120
Ω
resistor. If required, the output signals from the MC3486 can be potential-isolated
via an optocoupler.
