S7-1500 Motion Control V13 Update 3
380 Function Manual, 07/2014, A5E03879256-AC
Alarm reaction: Remove enable
Restart: Not required
Violation of the range limit for the incremental actual value.
Range violation in positive direction.
Home the axis/encoder to a valid actual value range.
Range violation in negative direction.
The change of the actual position in a position control clock
cycle is greater than the modulo length.
Adjust the modulo length of the employed encoder.
Alarm reaction: Remove enable
Restart: Not required
Drive/actuator at the logical address disrupted.
Check the device in regard to function, connections and
I/Os.
Alarm message from drive.
PROFIdrive: Drive signal "Control requested" failed.
PROFIdrive: Drive has shut down.
Alarm reaction: Remove enable
Restart: Not required
Communication with device disrupted.
PROFIdrive: Drive at bus failed (station failure). Check the device in regard to function, connections and
PROFIdrive: Signs of life of drive faulty. Check the device in regard to function, connections and
I/Os.
Compare the clock parameters of HW Config
(PROFIBUS line, slave OM for drive or encoder) and the
execution system. Tmapc and servo must be configured
in the same clock cycle time.
(Incorrect parameterization is indicated by reason
0x0080)
PROFIdrive: Encoder at bus failed (station failure). Check the device in regard to function, connections and
PROFIdrive: Signs of life of encoder faulty. Check the device in regard to function, connections and
I/Os. Compare the clock parameters of HW Config
(PROFIBUS line, slave OM for drive or encoder) and the
execution system. Tmapc and servo must be configured
in the same clock cycle time.
