♦
Direct modification of velocity of an active positioning process.
♦
The type of speed transfer and the ensuing braking ramp can be influenced by
previously modified acceleration times (ACCEL, ACCEL-).
Instruction Abbreviated
form
Meaning
POSR 0 SPEED
value
PR 0 SD Direct speed modification.
♦
These commands are processed regardless of a positioning process specified by
the interface (not during an internal data record procedure).
Instruction Abbreviated
form
Meaning
OUTPUT OT Set output
GOTO GO Adjusts data record indicator
and enables / blocks password.
♦
The axis must be at a standstill if modified VP parameters are to be transferred.
♦
The axis must be switched off if modified VC parameters are to be transferred
(e.g. via OUTPUT O0=1).
Instruction Abbreviated
form
Meaning
VALID
PARAMETER
VP Modified parameter accepted (not
configuration parameters).
VALID
CONFIGURATION
VC All parameters are accepted with VC.
Use the serial interface to query all status values, even during a positioning
process.
♦
Sxx transmitted, xx = number of the status value.
♦
COMPAX returns the current value.
Example:
S1
C
R
L
F
Response: S001:xxxxxxxx,xxxmm C
R
L
F
>
The decimal point for S1 - S12 is always the ninth digit after the ":".
8.6.3.3 Read and write program sets and parameters
Also possible during a positioning process.
Instruction Meaning
Nxxx: Instruction
Write set xxx with instruction
.
Pxxx=value
Write parameter xxx with value.
Pxxx="name"
(Only for P40-P49)
Assigns parameter xxx with name.
Example:
N005: POSA 100
C
R
L
F
or N005: PA 100 C
R

F
The POSA 100 instruction is written in data record 5.
Instruction Meaning
Nxxx
Read data record xxx.
Pxxx
Read parameter xxx.
