207446 <location>Load gear: Position tracking cannot be reset
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The position tracking cannot be reset.
Remedy: Reset the position tracking 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, if necessary, the absolute encoder adjusted (p2507).
207447 <location>Load gear: Position tracking, maximum actual value exceeded
Message Component number: %1, encoder data set: %2, drive data set: %3
value:
Drive object: SERVO, VECTOR
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, p0419, p2721
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 abso-
lute gearbox, revolutions, virtual)
207448 <location>Load gear: Position tracking, linear axis has exceeded the
maximum range
Message -
value:
Drive object: SERVO, VECTOR
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:
Here, only the motor encoder in the currently effective drive data set is monitored. The currently effec-
tive drive data set is displayed in x = r0051 and the corresponding motor encoder is specified 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.
