5.1 Basic signal flow

The functional core of the table positioning is the profile data management which

transmits the required profile data to the basic drive function "Positioning". The true

sequence control is carried out by a master control (e.g. PLC) which communicates with the

application via predefined ports.

5.3.2 Traversing range

By setting the traversing range the machine type/measuring system is set:

Parameter setting: Tab Application parameters  dialog level Overview

Traversing range

Unlimited The drive can traverse optionally in both directions without

reaching limitations.

• Positioning here generally is effected in the positioning

modes "Relative with/without TP" or "Speed with/

without TP".

• The positioning measuring system is reset to zero with

every new positioning process.

• By homing, the positioning measuring system receives a

fixed reference point (zero point), so that also the

positioning modes "Absolute with/without TP"can be

used. Then also the software limit positions for limiting

the traversing range are provided.

Limited After reaching the position limits, the drive must travel in the

opposite direction again.

• For positioning, the home position has to be known. By

homing, the positioning measuring system receives a

fixed reference point (zero point).

• Basically, monitoring to the internally maximum usable

value range (±231 increments) takes place (software limit

position monitoring of the internal value range). An

overflow of the value range results in the loss of the home

position.

• Additionally parameterisable software limit positions can

be activated on the user side for limiting the travel range.

Modulo The measuring system is repeated.

• If the cycles n set are exceeded a defined overflow occurs.

The cycle typically corresponds to a rotation or tool

distance in a rotative system.

• For positioning, the home position has to be known.

• Software limit positions are not effective.

• Absolute targets can be approached by exceeding the

measuring system limit, e.g. from 10° via 0° to 350°.

5.4 Profile data management

[5-2] Profile data management (schematic diagram)

The profile data management serves to file and manage up to 75 (travel) profiles.

A profile describes a motion request which can be converted by the basic drive function

"Positioning" into a rotary motion.

To execute a profile, 50 actions of type "Positioning" are available for the sequence

table.

The profile data management also enables the "teaching" of speed, acceleration/

deceleration and S-ramp times. "Teach" function ( 26)

(Standard) profile

Profile data set (profile no. 1 ... 75) in which the profile data are stored.

Mode

Selection of the positioning mode. Positioning modes ( 22)

Position

Target position or path distance to be traversed.

The position is either indicated as absolute or relative position.

• An absolute position always specifies the distance to the zero position defined:

absolute position = target position

• A relative position indicates the distance to the starting position (current position):

Relative position = target position - starting position

Speed

Maximum speed with which the target is to be approached.

• Depending on the profile parameter position, acceleration and deceleration, it is possible that the

drive may not reach the maximum speed. In this case, the graph would display a triangle instead of

a trapezium.

n Acceleration

o Travelling speed (is not reached here)

p Deceleration

q Target position (or feed distance)

Acceleration

Selection of the change in speed by which acceleration is to be carried out maximally.

• The following two acceleration types are distinguished:

–Constant acceleration: the speed increases linearly.

–Linearly increasing acceleration: The speed increases in S-shapes.

n Constant acceleration

o Linearly increasing acceleration

Deceleration

Selection of the change in speed by means of which deceleration to standstill is to be maximally effected

again.

S-ramp time

When the S-ramp time is selected for a profile, it is executed with S-shaped ramps, e.g. acceleration and

deceleration processes are started smoothly to reduce the jerk and thus prevent the drive components

from damage.

• The acceleration/deceleration specified in the profile are only reached after the defined S-ramp time

has elapsed.

• This type of acceleration/deceleration is required for e.g. sensitive machine parts with clearance.

• The slower acceleration increase with the S profile prolongs the positioning time compared to the

time optimal L profile.

n without jerk limitation (L profile)

o with jerk limitation (S profile)

Final speed

Selection of the speed by which the drive is to start the next profile after reaching the target position.

"Velocity changeover" or "Overchange" can be implemented with a final speed that is non-zero, i.e.

when the target position is reached, a second positioning process is started immediately without the

drive being decelerated to standstill at the first target position:

n Target position

o Final speed (here unequal "0")

Start of TP window / End of TP window

These profile parameters serve to restrict the range for a touch probe positioning (residual path

positioning) in which touch probes are to be detected.

Sequence profile with TP

Profile data set (profile no. 1 ... 75) in which the profile data of the profile are stored which is to be

executed after a touch probe has been detected.

• For the setting "0" no further profile connection by touch probe is effected.

Sequence profile without TP

Profile data set (profile no. 1 ... 75) in which the profile data of the profile is stored which is to be

executed after the standard profile has been executed (profile chaining).

• With the setting "0" no profile chaining is carried out.

• The sequence profile defined in this profile parameter is executed even if no touch probe has been

detected within the defined TP window.
