Position Target Interpreter

The acceptance and internal processing of S-0-0282, Positioning

command value to a value entered in parameter S-0-0430, Effective

target position is controlled via S-0-0346, Positioning control word.

At each edge of bit 0 (toggle bit) of S-0-0346 the content of S-0-0282,

Positioning command value, depending on bit 3 of S-0-0346, is

• copied to parameter S-0-0430

(when bit 3 = 0 → absolute target position)

- or -

• added to the value of S-0-0430

(when bit 3 = 1 → travel distance).

Note: If a positioning process is aborted by switching bits 1 and 2 of

S-0-0346 from status "00" to "01", "10" or "11", a repeated

edge reversal has to take place in bit 0 in order to start a new

positioning process! A residual path possibly present is

cleared, i.e. the status of bit 4 of S-0-0346 is automatically

interpreted as "1" during the next positioning process.

The drive acknowledges the acceptance of the positioning command

value via S-0-0419, Positioning command acknowledge (bit 0). This

allows realizing a data handshake for monitoring the command value

acceptance between master and drive.

Note: The active target position is displayed in parameter S-0-0430,

Effective target position.
