2.3.10 Programmable singleaxis dynamic response
Single axes
Single axes can be programmed:
In the part program
POS[Axis]=...
POSA[Axis]=...
SPOS[Axis]=...
SPOSA[Axis]=...
OS[Axis]=...
OSCILL[Axis]=...
In synchronized actions (command axes)
EVERY ... DO
POS[Axis]=...
SPOS [Spindle] = .....
MOV[Axis]=...
In the PLC FC15/FC16 and FC18
Dynamic response of an axis/spindle
The dynamic response of an axis is dependent on:
• the preset feed value (MD32060 POS_AX_VELO)
Can be programmed in the part program with FA[axis]= ..., or a feed
overrideOVRA[axis]= ... in percent.
Programmable in synchronized actions using FA[Axis]= ....
Modifiable from the PLC by entering FRate, or overwriting the axial override.
• The acceleration value (MD32300 MAX_AX_ACCEL)
Programmable indirectly in the part program by overwriting the machine data with
subsequent NewConfig, or directly using a percentage acceleration override
ACC[Axis]= ....
Modifiable indirectly in synchronized actions by overwriting the MD (no NewConfig
possible) or by executing an ASUB, or programmable directly using a percentage
acceleration override ACC[Axis]= ... (cannot be preset by the PLC).
The PLC has the same options as synchronized actions.
• The acceleration characteristics
Programmable in the part program using BRISKA(axis), SOFTA(axis), DRIVEA(axis) and
JERKA(axis).
Not programmable in synchronized actions (only directly using an ASUB).
Cannot be preset by the PLC (only indirectly using an ASUB).
