3.5.5 Write index and read index for the motion blocks

table

Via the write and read indices, the index of the motion block table the parameters of

which are to be read or written is specified. VTable uses the parameters automati-

cally for writing and reading. The write and read parameters are required for param-

eterization via keypad or for parameterization via a bus system (e.g. PROFIBUS).

Parameterize and read motion blocks with write index and read index via

software VPlus

The motion blocks can be parameterized in the user interface VPlus or in the motion

block table VTable. In the user interface VPlus, an index of the motion block table

can be set via parameter

Motion Block Sel. (Writing) 1200. The chosen index cor-

responds to a column in the motion block table. The settings of parameters 1202 to

1219, 1247 and 1248 are taken over in the selected index of the motion block

table. Via parameter

Motion Block sel. (Reading) 1201, the values of a selected

index can be read from the motion block table.

Parameter Settings

No. Description Min. Max. Fact. sett.

1200 Motion Block Sel. (Writing) 0 65

1201 Motion Block Sel. (Reading) 0 65

Setting defines the place where motion blocks are saved.

Settings for fixed parameterization

(non-volatile):

Settings only required for parameterization via

communication interface (volatile):

0: all motion blocks in EEPROM 33: all motion blocks in RAM

1 … 32: individual motion blocks in EEPROM 34 … 65: individual motion blocks in RAM

Note:

The settings"0" and "33" for

Motion Block Sel. (Writing) 1200 change

all motion blocks in EEPROM and RAM.

In the case of non-volatile storage (0…32), the changed values are still available

when power supply is switched on again.

In the case of volatile storage (33…65), the data is only stored in RAM. If the unit is

switched off, this data is lost and the data required are loaded from EEPROM after

restart.

Definition:

Motion block RAM = Motion block EEPROM +33
