Machine data Remarks
MD31060 $MA_DRIVE_AX_RATIO_NUMERA [4, AX1] = 5 Counter load gearbox for parameter set 5
MD31060 $MA_DRIVE_AX_RATIO_NUMERA [5, AX1] = 5 Counter load gearbox for parameter set 6
MD35130 $MA_AX_VELO_LIMIT [0...5, AX1] Setting for each parameter set*)
MD32800 $MA_EQUIV_CURRCTRL_TIME [0..5, AX1] Setting for each parameter set*)
MD32810 $MA_EQUIV_SPEEDCTRL_TIME [0..5, AX1] Setting for each parameter set*)
MD32910 $MA_DYN_MATCH_TIME [0...5, AX1] Setting for each parameter set*)
*) The appropriate line must be specified separately for each parameter set according to the applicable syntax rules.
Changeover
In order to switch over the position-control gain, the PLC user program selects the 4th
parameter set for machine axis X1.
• Requirement by PLC user program:
DB31, DBB9.0 – DBB9.2 = 3
– A request to change over to the 4th parameter set is sent for machine axis AX1.
– The parameter set is changed over once a delay has elapsed.
– Parameter set 4 is now active, in accordance with machine data with index "3"
• Feedback by NC:
DB31, DBB69.0 – DBB69.2 = 3
– The NC confirms/acknowledges the parameter-set changeover.
