192 Version: 1.2.1 MS249E C-863.12 Mercury Controller
Example 3:
Send: SEP 100 LEFT 0xA 20
Note: The maximum velocity must be set to 20 mm/s for
axis LEFT (axis was renamed with SAI). The setting is made
in nonvolatile memory and is therefore the new default,
but is not yet active. To use the new settings immediately,
you now have to load them to volatile memory (otherwise
they would become active after the next power-on or
reboot of the controller).
Send: RPA
Note: The new configuration is active now.
Send: SPA? LEFT 0xA
Receive: LEFT 0xA=20.00000
Note: Check the parameter settings in volatile memory.
SPA? (Get Volatile Memory Parameters)
Description:
Queries the value of a parameter of a specified element
from volatile memory (RAM).
You can obtain a list of the available parameters with HPA?
(p. 159).
Format:
SPA? [{<ItemID> <PamID>}]
Arguments:
<ItemID> is the element for querying a parameter in
volatile memory. See below for details.
<PamID> is the parameter identifier, can be written in
hexadecimal or decimal format. See below for details.
Response:
{<ItemID> <PamID>"="<PamValue> LF}
where
<PamValue> is the value of the specified parameter for the
specified element
Troubleshooting:
Illegal element identifier, wrong parameter ID
Notes:
With the C-863.12, you can query either all parameters or
one single parameter per SPA? command.
