You can assign a maximum of 15 internal digital output signals to the SINAMICS V90 servo
drive. For detailed information about these signals, see the table below:

1 RDY Servo ready
• 1: ready to operate
• 0: drive not ready (alarm occurs or enable signal is
missing)
✓ ✓ ✓ ✓
2 FAULT Fault
• 1: in fault status
• 0: no fault
✓ ✓ ✓ ✓
3 INP In-position signal
• 1: number of droop pulses is in the preset in-position
range (parameter p2544)
• 0: droop pulses are beyond the in-position range
✓ ✓ X X
4 ZSP Zero speed detection
• 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).
✓ ✓ ✓ ✓
5 SPDR Speed reached
• 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.
X X ✓ X
6 TLR Torque limit reached
• 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
✓ ✓ ✓ X
7 SPLR Speed limit reached
• 1: the speed has nearly (internal hysteresis, 10 rpm)
reached the speed limit.
• 0: the speed has not reached the speed limit.
✓ ✓ ✓ X
8 MBR Motor holding brake
• 1: motor holding brake is closed
• 0: motor holding brake is released
Note
: MBR is only status signal because the control and
the power supply of the motor holding brake is realized
with separate terminals.
