201651 <location>SI CU: Synchronization safety time slices unsuccessful
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The "Safety Integrated" function requires a synchronization of the safety time slices
between the control unit (CU) and motor module (MM) and between the control unit and
the higher-level control. This synchronization routine was not successful.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, decimal):
Only for internal Siemens troubleshooting.
Remedy: - carry-out a POWER ON (power off/on) for all components.
- upgrade the motor module software.
- upgrade the control unit software.
- upgrade the software of the higher-level control.
Note:
CU: Control unit
MM: Motor module
SI: Safety Integrated
201652 <location>SI CU: Monitoring clock cycle not permissible
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: One of the Safety Integrated monitoring clock cycles is not permissible:
- the drive-based monitoring clock cycle cannot be maintained due to the communication
conditions required in the system.
- the monitoring clock cycle for safe motion monitoring functions with the higher-level
control is not permissible (p9500).
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, decimal):
- for enabled drive-based SI monitoring (p9601/p9801 > 0):
Minimum setting for the monitoring clock cycle (in µs).
- with the motion monitoring function enabled (p9501 > 0):
100: No matching monitoring clock cycle was able to be found.
101: The monitoring clock cycle is not an integer multiple of the position controller clock
cycle.
102: An error has occurred when transferring the DP clock cycle to the motor module (MM).
Remedy: For enabled drive-based SI monitoring (p9601/p9801 > 0):
- upgrade the control unit software.
For enabled motion monitoring function (p9501 > 0):
- correct the monitoring clock cycle (p9500) and carry-out POWER ON.
Note:
CU: Control unit
MM: Motor module
SI: Safety Integrated
201655 <location>SI CU: Align monitoring functions
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
