A06, brush wear monitoring, limit signal, isolated

Category
Motor-relevant options
Function
The evaluation is realized via an isolated signal contact in the motor (for Siemens DC
motors, order code A06 according to Catalog DA12, Part 1, protection and monitoring
equipment).
In the case of a fault, depending on the parameterization of the converter unit, alarm A60025
(yellow LED on the AOP30) or fault F60025 (red LED on the AOP30). For parameterization
to "fault", the group signal "fault" is displayed and the SINAMICS DCM is switched off.
The messages "alarm" and "fault" can also be evaluated via the fieldbus interface.
Safe electrical separation between the signal and power circuit of the motor must be
guaranteed!
Connection
The brush length monitoring signal must comply with PELV according to DIN EN 61140.
The signal is connected to terminal strip –X2, where it is supplied with 24 V.

Parameter assignment
The system-specific circuit diagram shows which binary input at the converter is used to
evaluate this monitoring device. This binary input should be parameterized as input signal at
p50486.
