F07492 (A) EPOS: STOP cam plus reached
Drive object: SERVO, VECTOR
Reaction: OFF3
Acknowledge: IMMEDIATELY
Cause: A zero signal was detected at binector input BI: p2570, i.e. the STOP cam plus was reached.
For a negative traversing direction, the STOP cam plus was reached - i.e. the wiring of the STOP cam is incorrect.
See also: p2570 (EPOS STOP cam plus)
Remedy: - leave the STOP cam plus in the negative traversing direction and return the axis to the valid traversing range.
- check the wiring of the STOP cam.
Reaction upon A: NONE
Acknowl. upon A: NONE
F07493 LR: Overflow of the value range for the position actual value
Drive object: SERVO, VECTOR
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The value range (-2147483648 ... 2147483647) for the position actual value representation was exceeded.
When the overflow occurs, the status "referenced" or the status "adjustment absolute measuring system" is reset.
Fault value (r0949, interpret decimal):
1: r2521 has exceeded the value range for the position actual value display.
2: r0483 and/or r2723 has exceeded the value range for the position actual value display.
3. The factor to convert the absolute position (r0483 and/or r2723) from increments to LUs is greater than 1.0.
Remedy: If required, reduce the traversing range or position resolution (p2506).
Increase the fine resolution of absolute position actual value p419.
Reference to fault value 3:
If the factor inc2lu to convert the absolute position (r0483 or r2723) from increments to LUs is greater than 1.0, then
it is not possible to make an adjustment as an overflow can occur.
The factor inc2lu is calculated as follows for rotary encoders:
1. Motor encoder without position tracking:
inc2lu = p2506 * p0433 * p2505 / (2^p0419 * p0408 * p0432 * p2504)
2. Motor encoder with position tracking for the measuring gearbox:
inc2lu = p2506 * p2505 / ( 2^p0419 * p0408 * p2504)
3. Motor encoder with position tracking for the load gearbox:
inc2lu = p2506 * p0433 / (2^p0419 * p0408 * p0432)
4. Motor encoder with position tracking for the load and measuring gearbox:
inc2lu = p2506 / (2^p0419 * p0408)
5. Direct encoder without position tracking:
inc2lu = p2506 * p0433 / (2^p0419 * p0408 * p0432)
6. Direct encoder with position tracking for the measuring gearbox:
inc2lu = p2506 / (2^p0419 * p0408)
Example re 2:
p2506 = 300000
p0419 = 9
p0408 = 2048
p2505 = 7 LoadU
p2504 = 2 MotU
inc2lu = 1.001358032
F07494 LR: Drive Data Set changeover in operation
Drive object: SERVO, VECTOR
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: A drive data set changeover (DDS changeover) when the mechanical relationships change (p2503 .. 2506), the
direction of rotation (p1821) or the encoder assignment (p2502) were requested during operation.
Remedy: To changeover the drive data set, initially, exit the "operation" mode.
