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:
112
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.
OLL Overload level reached
1: the motor has reached the parameterizable output overload level (p29080
•
in % of the rated torque; default: 100%; max: 300%).
0: the motor has not reached the overload level.
•
RDY_ON Ready for servo on
1: the drive is ready for servo on.
•
0: the drive is not ready for servo on (a fault occurs, the main power supply is
•
missing, or STW1.1 and STW1.2 are not set to 1).
Note: after the drive is in "servo on" state, the signal remains at high level (1)
unless the above abnormal cases happen.
INP In-position signal
1: the number of droop pulses is in the preset in-position range (parameter
•
p2544).
0: the number of droop pulses is beyond the preset in-position range.
•
