DOK-INDRV*-MP*-02VRS**-FK01-EN-P

• parameterization of up to 64 positioning blocks; each with target

position/travel distance, velocity, acceleration, deceleration and jerk

• defined block acceptance by toggling bit 0 in S-0-0346 with reaction

time t

R_Strobe

= t

position

Note: With field bus drives, the I/O mode and control via the parallel

interface are exceptions. In these cases acceptance takes place by a

0-1 edge of bit 0 in P-0-4060.

• block selection and acknowledgment via separate parameters

(→handshake principle)

• positioning modes to be freely parameterized

• relative positioning

• absolute Positioning

• infinite travel (positive or negative)

• single-block or sequential block mode with different conditions for

advance:

• block advance with switch cams

• block advance at defined position value

block transition with "old" or "new" positioning velocity

• positioning while taking command value mode into account

(shortest distance, positive direction, ...)

• residual path processing can be activated (→ no loss of incremental

dimension)

• "slow travel" mode can be activated

• velocity override to be set

Fields of Application

Sequential block processing allows executing several positioning blocks

processed in direct sequence without having to give a new start signal

each time. Typical fields of application are:

• There is none or only a very simple higher-level control unit available

and control is realized via digital I/Os only or a field bus control word

(I/O mode with field bus interface).

• There are quick reaction times or block advances required. The

required motion profiles can be represented in the drive by the

maximum possible 64 positioning blocks.

• There are positioning processes required which cover long distances

at high speeds (rapid traverse) and then position at the end position at

low speed without any intermediate stops; for example:

• taking up or putting down transport goods in handling robots

• execution of joining processes in assembly facilities
