direction greater than the programmed target position window!

The following applies to the braking procedure:

starting position + braking distance – target position > S-0-0418

→ positioning in negative direction not allowed; i.e. drive must move to

target in positive direction

• Case 5:

current velocity = 0

→ drive moves to target position in negative direction

The following applies to the braking procedure:

starting position + braking distance – target position < S-0-0418

→ positioning in negative direction allowed; i.e. drive must move to

target in negative direction

• Case 6:

current velocity negative and braking distance smaller than the

difference between starting position and next target position

→ drive directly moves to target position in negative direction

The following applies to the braking procedure:

starting pos. + braking distance (negative) – target position < S-0-0418

→ positioning in negative direction directly at target position

• Case 7:

current velocity negative and braking distance greater than the

difference between starting position and next target position

→ drive brakes to zero and positions at next target position in positive

direction

The following applies to the braking procedure:

starting pos. + braking distance (negative) – target position > S-0-0418

→ drive brakes to zero and positions positively at next target position

Note: As a matter of principle, the braking distance is calculated

before starting the positioning movement; the result of the

calculation influences the subsequent positioning procedure.

In the "shortest distance" mode the drive positions at the effective target

position (cf. S-0-0430) over the shortest possible distance.

Note: Depending on S-0-0417, Velocity threshold for positioning

in modulo format, the drive moves with or without reversal of

direction.

The following examples show the behavior of the drive in the "shortest

distance" mode with different velocities.

• Case 8:

current velocity positive and > S-0-0417; braking distance greater than

the distance between starting position and next target position

→ drive moves to target position, that can be reached without reversal

of direction, in positive direction

The following applies to the braking procedure:

starting position + braking distance – target position > S-0-0418

→ positioning in negative direction not allowed; i.e. drive must move to

target in positive direction
