4 Faults and alarms
4.2 List of faults and alarms
N31800 (F)
Encoder 1: Group signal
Message value:
-
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction:
ENCODER (IASC/DCBRK, NONE)
Acknowledge:
NONE
Cause:
The motor encoder has detected at least one fault.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy:
Evaluate the other messages that are presently available.
Reaction upon F:
ENCODER (IASC/DCBRK, NONE)
Acknowl. upon F:
IMMEDIATELY
F31801 (N, A)
Encoder 1 DRIVE-CLiQ: Sign-of-life missing
Message value:
Component number: %1, fault cause: %2
Message class:
Internal (DRIVE-CLiQ) communication error (12)
Drive object:
DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction:
ENCODER (IASC/DCBRK, NONE)
Acknowledge:
IMMEDIATELY
Cause:
A DRIVE-CLiQ communication error has occurred from the Control Unit to the encoder involved.
Fault cause:
10 (= 0A hex):
The sign-of-life bit in the receive telegram is not set.
Note regarding the message value:
The individual information is coded as follows in the message value (r0949/r2124):
0000yyxx hex: yy = component number, xx = error cause
See also: p0491 (Motor encoder fault response ENCODER)
Remedy:
- check the electrical cabinet design and cable routing for EMC compliance
- replace the component involved.
See also: p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave)
Reaction upon N:
NONE
Acknowl. upon N:
NONE
Reaction upon A:
NONE
Acknowl. upon A:
NONE
F31802 (N, A)
Encoder 1: Time slice overflow
Message value:
%1
Message class:
Hardware / software error (1)
Drive object:
DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction:
ENCODER (IASC/DCBRK, NONE)
Acknowledge:
IMMEDIATELY
Cause:
A time slice overflow has occurred in encoder 1.
Fault value (r0949, interpret hexadecimal):
yx hex: y = function involved (Siemens-internal fault diagnostics), x = time slice involved
x = 9:
Time slice overflow of the fast (current controller clock cycle) time slice.
x = A:
Time slice overflow of the average time slice.
x = C:
Time slice overflow of the slow time slice.
yx = 3E7:
Timeout when waiting for SYNO (e.g. unexpected return to non-cyclic operation).
See also: p0491 (Motor encoder fault response ENCODER)
Remedy:
Increase the current controller sampling time
Note:
For a current controller sampling time = 31.25 µs, use an SMx20 with order number 6SL3055-0AA00-5xA3.
