A30502 Power unit: DC link overvoltage
Reaction: NONE
Acknowledge: NONE
Cause: The power unit has detected overvoltage in the DC link on a pulse inhibit.
- device connection voltage too high.
- line reactor incorrectly dimensioned.
Alarm value (r0949, interpret decimal):
DC link voltage [1 bit = 100 mV].
See also: r0070 (Actual DC link voltage)
Remedy: - check the device supply voltage (p0210).
- check the dimensioning of the line reactor.
See also: p0210 (Drive unit line supply voltage)
F30600 SI P2: STOP A initiated
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-integrated "Safety Integrated" function on processor 2 has detected an error and initiated a STOP A.
- forced checking procedure of the safety shutdown path via processor 2 unsuccessful.
- subsequent response to fault F30611 (defect in a monitoring channel).
Fault value (r0949, interpret decimal):
0: Stop request from processor 1.
1005: Pulses suppressed although STO not selected and there is no internal STOP A present.
1010: Pulses enabled although STO is selected or an internal STOP A is present.
9999: Subsequent response to fault F30611.
Remedy: Select Safe Torque Off and de-select again.
For fault value = 9999:
- carry out diagnostics for fault F30611.
Note:
STO: Safe Torque Off
F30611 (A) SI P2: Defect in a monitoring channel
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-integrated "Safety Integrated" function on processor 2 has detected a fault in the crosswise data compar-
ison between the two monitoring channels and has initiated a STOP F.
As a consequence of this fault, fault F30600 (SI P2: STOP A initiated) is output.
Fault value (r0949, interpret decimal):
0: Stop request from processor 1.
1 ... 999:
Number of the cross-compared data that resulted in this fault. This number is also displayed in r9795.
2: SI enable safety functions (p9601, p9801). Crosswise data comparison is only carried out for the supported bits.
3: SI F-DI changeover tolerance time (p9650, p9850).
8: SI PROFIsafe address (p9610, p9810).
9: SI debounce time for STO (p9651, p9851).
1000: Watchdog timer has expired.
Within the time of approx. 5 x p9650, alternatively, the following was defined:
- Too many signal changes have occurred at the F-DI.
- Via PROFIsafe, STO was too frequently initiated (also as subsequent response).
1001, 1002: Initialization error, change timer / check timer.
2000: Status of the STO selection for both monitoring channels are different.
2001: Feedback of the safe pulse suppression on the two monitoring channels are different.
2003: Status of the STO terminal on the processor 1 and processor 2 are different.
6000 ... 6999:
Error in the PROFIsafe control.
For these fault values, the failsafe control signals (failsafe values) are transferred to the safety functions.
The significance of the individual message values is described in safety fault F01611.
Remedy: Re fault values 1 ... 999 described in "Cause":
- check the cross data comparison that resulted in a STOP F.
- carry out a POWER ON (power off/on).
