F01652 SI P1 (CU): Monitoring clock cycle not permissible
Explanation One of the Safety Integrated monitoring clock cycles is not permissible:
● The monitoring clock cycle integrated in the drive cannot be maintained due to the communication
conditions requested in the system.
● The monitoring clock cycle for the safety-related motion monitoring functions with the higher-level control
is not permissible (p9500).
● The actual value sensing clock cycle for safe motion monitoring is not permissible (p9511).
● The sampling time for the current controller cannot be supported (p0112, p0115[0]).
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, interpret decimal):
When motion monitoring is not enabled (p9601.2 = p9801.2 = 0, p9501 = 0), the following applies:
Minimum setting for the monitoring clock cycle (in μs).
If motion monitoring is enabled (p9601.2 = p9801.2 = 1 and/or p9501 > 0), the following applies:
100: It was not possible to find an appropriate monitoring clock cycle.
101: The monitoring clock cycle is not an integer multiple of the actual value clock cycle.
102: An error has occurred when transferring the actual value sensing clock cycle to the Motor Module.
103: An error has occurred when transferring the actual value acquisition clock cycle to the Sensor Module.
104, 105: Four times the current controller sampling time is greater than 1 ms for operation with non-clock-
cycle synchronous PROFIBUS.
Four times the current controller sampling time is greater than the DP clock cycle for operation with clock-
cycle synchronous PROFIBUS.
The DP clock cycle is not an integer multiple of the current controller sampling time
Remedy When the SI monitoring, integrated in the drive is enabled (p9601/p9801 > 0).
Upgrade the firmware of the Control Unit to a later version.
When the motion monitoring is enabled (p9501 > 0):
Correct the monitoring clock cycle (p9500) and carry out a POWER ON.
Re fault value = 101:
The actual value acquisition clock cycle corresponds to the position control clock cycle/DP clock cycle (factory
setting).
For the motion monitoring functions integrated in the drive (p9601/p9801bit 2 = 1), the actual value acquisition
clock cycle can be directly parameterized in p9511/p9311.
For fault value 104, 105:
Set your own actual value acquisition clock cycle in p9511.
Restrict operation to a maximum of two vector drives. For the default settings in p0112, p0115, the current
controller sampling time is automatically reduced to 250 ms. If the default values have been changed, then
the current controller sampling time (p0112, p0115) must be correspondingly set.
When operating with isochronous PROFIBUS, increase the DP clock cycle so that an integer clock cycle
ratio of at least 4:1 is obtained between the DP clock cycle and the current controller sampling time. We
recommend a pulse duty factor of at least 8:1.
With firmware version 2.5, please ensure that in the drive parameter p9510 is set to 1 (isochronous operation).
