5.3 Control of "STO" and "SS1" via terminals on the Control Unit and the Motor/Power Module
Terminal
Max. connectable cross-section: 1.5 mm
DI: Digital input; DI/DO: Bidirectional digital input/output; M: Electronics ground; M2: Reference ground
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. Route the ground reference for 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.
Wiring
The control cables should be permanently routed (e.g. cable duct, retained using cable ties).
Signal cables and encoder cables should be installed separated from one another.
The shields of the control cables should be grounded through the largest possible surface
area immediately after they enter the control cabinet.
Outside the control cabinet, the cables must be routed in such a way that they are safe to
walk on (e.g. as specified in IEC 60204-1).
