F01688 SI Motion CU: Actual value synchronization not permissible
Response OFF2
Acknowledg‐ IMMEDIATELY (POWER ON)
ment
Explanation It is not permissible to enable actual value synchronization for a 1-encoder system.
● Simultaneously enabling actual value synchronization and a monitoring function with absolute reference
(SCA/SLP) is not permitted.
● Simultaneously enabling actual value synchronization and safe position via PROFIsafe is not permitted.
Note:
This fault results in a STOP A that cannot be acknowledged.
Remedy Either deselect the "actual value synchronization" function or the monitoring functions with absolute reference
(SCA/SLP) and carry out a POWER ON.
Either deselect the "Actual value synchronization" function - or do not enable "Safe position via PROFIsafe".
C01689 SI Motion: Axis re-configured
Response OFF2
Acknowledg‐ POWER ON
ment
Explanation The axis configuration was changed (e.g. changeover between a linear axis and rotary axis). Parameter
p0108.13 is internally set to the correct value.
Note:
This fault does not result in a safety stop response.
Fault value (r0949, interpret decimal):
Parameter number of the parameter that initiated the change.
See also: p9502 (SI Motion axis type (Control Unit))
Remedy The following must be carried out after the changeover:
● Exit the safety commissioning mode (p0010).
● Save all parameters (p0977 = 1 or "Copy RAM to ROM").
● Carry out a POWER ON.
Once the Control Unit has been powered up, safety message F01680 or F30680 indicates that the check‐
sums at the drive in r9398[0] and r9728[0] have changed. Therefore, the following must be carried out:
● Reactivate the Safety commissioning mode.
● Complete the safety commissioning of the drive.
● Exit the safety commissioning mode (p0010).
● Save all parameters (p0977 = 1 or "Copy RAM to ROM").
● Carry out a POWER ON.
Note:
For the commissioning software, the units are only displayed consistently after a project upload.
