Name
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.
•
REFOK Referenced
1: referenced.
•
0: not referenced.
•
STO_EP STO active
1: the enable signal is missing, indicating that STO is active.
•
0: the enable signal is available, indicating that STO is inactive.
•
Note: STO_EP is only a status signal for STO input terminals but not a safe DO
for the Safety Integrated function.
