4 Faults and alarms
4.2 List of faults and alarms
SINAMICS DCM
948 List Manual (LH8), 02/2015, 6RX1800-0ED76
Remedy: Re alarm value = 1:
Set the output limit in p2291 higher than in p2292.
See also: p2291 (Technology controller maximum limiting), p2292 (Technology controller minimum limiting)
Reaction upon N: NONE
Acknowl. upon N: NONE
F07447 Load gear: Position tracking, maximum actual value exceeded
Message value: Component number: %1, encoder data set: %2, drive data set: %3
Message class: Application / technological function faulted (17)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: When the position tracking of the load gear is configured, the drive/encoder (motor encoder) identifies a maximum
possible absolute position actual value (r2723) that can no longer be represented within 32 bits.
Maximum value: p0408 * p2721 * 2^p0419
Fault value (r0949, interpret hexadecimal):
ccbbaa hex
aa = encoder data set
bb = component number
cc = drive data set
See also: p0408 (Rotary encoder pulse number), p0419 (Fine resolution absolute value Gx_XIST2 (in bits)), p2721
(Load gear rotary absolute encoder revolutions virtual)
Remedy: - reduce the fine resolution (p0419).
- reduce the multiturn resolution (p2721).
See also: p0419 (Fine resolution absolute value Gx_XIST2 (in bits)), p2721 (Load gear rotary absolute encoder
revolutions virtual)
F07448 (A) Load gear: Position tracking, linear axis has exceeded the maximum range
Message value: -
Message class: Application / technological function faulted (17)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: For a configured linear axis/no modulo axis, the currently effective motor encoder (encoder 1) has exceeded the
maximum possible traversing range.
For the configured linear axis, the maximum traversing range is defined to be 64x (+/- 32x) of p0421. It should be
read in p2721 and interpreted as the number of load revolutions.
Note:
Only the motor encoder in the currently effective drive data set is monitored here. The actual effective drive data set
is displayed in x = r0051 and the corresponding motor encoder is specified in in p0187[x].
Remedy: The fault should be resolved as follows:
- select encoder commissioning (p0010 = 4).
- reset position tracking, position (p2720.2 = 1).
- de-select encoder commissioning (p0010 = 0).
The fault should then be acknowledged and the absolute encoder adjusted.
Reaction upon A: NONE
Acknowl. upon A: NONE
F07449 (A) Load gear: Position tracking actual position outside tolerance window
Message value: %1
Message class: Application / technological function faulted (17)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: When powered down, the currently effective motor encoder was moved through a distance greater than was
parameterized in the tolerance window. It is possible that there is no longer any reference between the mechanical
system and encoder.
