Validity: Rule, Task
This keyword is used by RTE for the output of the alarm "40#nAx Retentive Transducer : max movem. exceeed" in case it is desired to have quota retentivity at the shutdown of the controlled machine.
This performance is available for CAN402-COE type transducers, Absolute Encoders connected to ABS.AXI boards via SSI and integer Registers R and NVR.
Syntax |
I32 max_d_raw (I32 n) |
|---|---|
n |
Axis index. Minimum representable number: 1 Maximum representable number: 32 |
Notes |
Its unit of measurement is: Units. Default: •A quarter of the bit size of the rawcp (if i32 0x3FFFFFFF) •In case of fieldbus transducers (canopen), the initialization value is a quarter of the absolute component |
If the management of the retentive axis quota from configurator is enabled then RTE performs the following management when the system is turned on again:
•Checks the value of the axis variable C0_DONE.
•If = 1 it imposes the real quota stored at power off, modified by the variation detected between the rawcp stores and the one detected at switch on.
If the absolute value of the variation is greater than the MAX_D_RAW parameter, the alarm "40#nAx Retentive Transducer : max movem. exceeed" is generated.
Example
; the maximum possible variation of axis 1 is the one in r(101) max_d_raw(1) = r(101) |
Example
; the maximum possible variation of axis 2 is stored in r(202) r(202) = max_d_raw(2) |
