Dos - Siemens SINAMICS V90 Operating Instructions Manual

Wiring
The digital inputs support both PNP and NPN types of wirings. You can find detailed
information from the following diagrams:

DOs

You can assign a maximum of 10 internal digital output signals to the SINAMICS V90 PN
servo drive. For detailed information about these signals, see the table below:

NPN wiring
Name
RDY Servo ready
1: the drive is ready.
•
0: the drive is not ready (a fault occurs or the enable signal is missing).
•
FAULT Fault
1: in the fault state.
•
0: no fault.
•
ZSP Zero speed detection
1: motor speed ≤ zero speed (can be set with parameter p2161).
•
0: motor speed > zero speed + hysteresis (10 rpm).
•
TLR Torque limit reached
1: the generated torque has nearly (internal hysteresis) reached the value of
•
the positive torque limit or negative torque limit.
0: the generated torque has not reached any torque limit.
•
MBR Motor holding brake
1: the motor holding brake is engaged.
•
0: the motor holding brake is released.
•
Note: MBR is only a status signal because the control and the power supply of
the motor holding brake are realized with separate terminals.
