12.5 Connection X120
Encoder connection X120 is an integral part of terminal modules XI6 and RI6.
You can simulate or evaluate the following encoders on X120:
• SSI encoder
• incremental encoder (TTL)
• Hall sensors via LA6 adapter box for commutation of a synchronous linear
motor
For detailed information regarding the relevant encoder specification and
supply as well as the corresponding terminals, see 7.4.7 X120.
Function of the X120 connector on the Extended RI6 I/O terminal module (X16
or R16).
If an encoder simulation is parameterized, the source as well as the scaling can
be set in H80 and following.
H121 and H122 together indicate a fraction that is used to convert the raw
values of the encoder connected to X120 into mechanical quantities.
The unit of the mechanical target quantity is revolutions for rotational encoders
and mm for linear encoders.
H121 and H122 together indicate a fraction that is used to convert the raw
values of the encoder connected to X120 into mechanical quantities.
The unit is lines (before four levels of evaluation) for incremental encoders and
LSBs for SSI encoders. For SSI encoders with 13 bits per revolution, enter 2
13
= 8192 LSBs, for example.
The parameter indicates whether the encoder connected to X120 is a rotational
or translational measuring system. This affects the unit of measure of H121 and
where the encoder is located in the axis model in relation to the feed.
If there is an incremental encoder without zero track at X120, the cable
monitoring for the zero track can be switched off at this point.
