The 767-5201 module is a hybrid module, which is designed to connect 2
incremental encoders or SSI encoders. Each input can be individually configured
to one of the encoder types.
In addition, two of the connections can each be parameterized with two signal
channels as digital inputs or outputs.
Thus, the module offers space for connecting up to four digital sensors or
actuators. These can be configured as sub-signals to the counter channels, e.g. as
gate, latch, preset, or cam signals.
The following connections are possible:
•
2 x M12, A-coded, 8 poles, either for connecting TTL incremental encoders
or SSI encoders
•
2 x M12, A-coded, 5 poles, usable either for fast DIOs (or optionally as a
PWM output)
Counter function
•
Incremental encoder interface function
When functioning as an incremental encoder interface, the module detects
the pulses from a connected incremental encoder. In this case, the rotational
direction of the encoder is recognized automatically due to the functionality
of the two clock signals.
Another option allows for the connection of a C track, by means of which a
zero set pulse or a preset pulse can be triggered.
•
SSI encoder interface function
When functioning as an SSI encoder interface, the current counter reading
of the encoder is read in binary using an SSI interface (Synchronous Serial
Interface). The counter reading is stored in the module and output as a
process value.
Counter mode
•
Event counter:
In the basic "counter" function, the module counts the pulses arriving at the
pulse input, whereby it automatically detects the counting direction.
•
Gate time/frequency measurement:
The pulses are counted that occur within the gate time (a gate time of 1 s
results in the frequency in Hz).
•
Gate time/cycle duration measurement:
The cycle duration is determined in µs.
A series of control functions have been implemented in the module, which can be
used to control the behavior of the counter.
