Positioning control

3.4.9 Travel profile generator and setpoints

3−61

EDSVS9332P−EXT DE 2.0

l The S profile must be activated before starting the positioning process.

l S profile is activated as follows:

Connect input POS−S−RAMPS" with 1−signal, e. g. assign FIXED1 directly or set

FCODE−471.B1 = 1 (default setting).

l With POS−PARAM−RD" you can switch between both profiles even during the positioning

process.

When changing from the L profile to the S profile during acceleration/deceleration, the S

profile starts with acceleration 0 all the same. The process is prolonged accordingly.

Tip!

l The jerk remains unchanged when the acceleration is changed.

– If a target position cannot be reached with these parameters (e. g. with TP positioning or

velocity changeover) the target position is overtravelled. Afterwards the drives changes its

direction of rotation and travels to the target position.

– If a positioning process with or without final speed (changeover of velocity) is followed by a

positioning process in opposite direction, the acceleration will be reduced to 0 before it is

built up in opposite direction.

l For the S−profile, the deceleration is automatically equated with the acceleration in the PS.

Inputs for the deceleration are not considered.

l Special feature when stopping in manual operation, homing, PS−CANCEL, program stop:

 Stops are always realised with linear ramps!

Firmware version ³ 2.5:

Under C1259/1.../3 it is possible to change to S ramps for stopping.

Stopping with S ramp

The corresponding setting parameters for the S ramp can be found in the GDC under the following

menu: POS functions / S−ramps". This function can be set with code C1258.

When the S−ramp function is activated, the default settings of the controller cause the drive to be

stopped in the case of the following functions with linear ramp:

– Manual jog,

– Prg−stop,

– PS−CANCEL and

– Homing

With firmware version ³V2.5 the controller can be switched to stopping with S−ramp for the following

functions when the S−ramp function is activated:

– Manual jog (C1258/1),

– Prg−Stop (C1258/2),

– PS−CANCEL (C1258/3)
