Siemens SIMOTION Equipment Manual

The electrically isolated inputs can be used as freely addressable inputs.
Note
An open input is interpreted as "low".
For the DI 22 digital input to function correctly, the coupled reference potential (DI 22-) must be
connected. The following options are available:
• Connect the coupled reference potential of the digital input to M1, M2 or M.
This assigns the input to the potential of the associated pin.
• Create a bridge between terminal M and terminal M1 or M2.
Caution: This will cancel the electrical isolation for this digital input!
Bidirectional digital I/Os (DI/DO)
The SIMOTION D410-2 provides eight bidirectional digital I/Os (DI/DO) that can be
parameterized channel-speci󹪝c as digital input or output.
This produces the following usage options for the parameterization of the DI/DO:
Table 4-22 DI/DO usage options
DI/DO Interface Use
Parameterization of the DI/DO as digital inputs:
DI/DO 8 to DI/DO 15 X121, X131 "Fast inputs" for measuring inputs
1)
or homing inputs
DI/DO 8 to DI/DO 15 X121, X131 Freely addressable inputs
Parameterization of the DI/DO as digital outputs:
DI/DO 8 to DI/DO 15 X121, X131 "High-speed" outputs of output cams
DI/DO 8 to DI/DO 15 X121, X131 Freely addressable outputs
1)
With a signal edge at the relevant input, the current actual values of one or more encoders are
measured with positioning accuracy to determine lengths and distances. The assignment of the inputs
is not 󹪝xed, and the special use is activated in the SIMOTION SCOUT engineering system.
Note
An additional external electronics power supply via terminal X124 is required in two cases:
• If the digital outputs DO 8 to DO 15 are in use, the power supply needs to be connected to
X124.
• The Power Module provides the electronics power supply of the SIMOTION D410-2. If the
SIMOTION D410-2 needs to remain functional when the Power Module is switched o󹪜, X124
must be used for the electronics power supply.
Inductive loads
If the digital inputs are used together with inductive loads, it must be ensured that the
permissible voltage range of -30 V to +30 V for digital inputs is not exceeded by the switching
overvoltage of inductive loads. This is preferably achieved by using auxiliary contacts on the
contactor/relay for the digital inputs.
