X124 Electronics Power Supply - Siemens SINAMICS Equipment Manual

Control Units
3.2 Control Unit CU320-2 DP (PROFIBUS)
Terminal
Type: Spring-loaded terminal 3
DI: digital input; DI/DO: bidirectional digital input/output; M: electronics ground; M2: reference potential
1)
The rapid inputs can be used as probe inputs or as inputs for the external zero mark
2)
Data for: V = 24 V; load 48 Ω; high ("1") = 90% V
3)
cc
The maximum cable length that can be connected is 30 m.
Note
Ensuring the function of digital inputs
An open input is interpreted as "low".
To enable the digital inputs (DI) to function, terminal M2 must be connected.
This is achieved by using one of the following measures:
1. Providing the ground reference of the digital inputs
2. A jumper to terminal M
Note: This removes isolation for these digital inputs.
Note
If the 24 V supply is briefly interrupted, then the digital outputs are deactivated during this time.
