Dos - Siemens SINAMICS V90 Operating Instructions Manual

4.3.1.2

DOs

You can assign a maximum of 14 internal digital output signals to the SINAMICS V90 servo
drive. For detailed information about these signals, see the table below:
No. Name
1 RDY Servo ready
•
•
2 FAULT Fault
•
•
3 INP In-position signal
•
•
4 ZSP Zero speed detection
•
•
5 SPDR Speed reached
•
•
6 TLR Torque limit reached
•
•
7 SPLR Speed limit reached
•
•
8 MBR Motor holding brake
•
•
Note: MBR is only status signal because the control and
the power supply of the motor holding brake is realized
with separate terminals.

Descriptions
1: ready to operate
0: drive not ready (alarm occurs or enable signal is
missing)
1: in fault status
0: no fault
1: number of droop pulses is in the preset in-position
range (parameter p2544)
0: droop pulses are beyond the in-position range
1: motor speed is equal with or lower than the zero
speed (can be set with parameter p2161).
0: motor speed is higher than zero speed + hysteresis
(10 rpm).
1: motor actual speed has nearly (internal hysteresis
10 rpm) reached the speed of the internal speed com-
mand or analog speed command. The speed ap-
proaching range can be set via parameter (p29078)
0: speed difference between speed setpoint and actual
is larger than internal hysteresis.
1: the generated torque has nearly (internal hysteresis)
reached the value of the positive torque limit, negative
torque limit or analog torque limit
0: the generated torque has not reached the limit
1: the speed has nearly (internal hysteresis, 10 rpm)
reached the speed limit.
0: the speed has not reached the speed limit.
1: motor holding brake is closed
0: motor holding brake is released
