Description
The adjustment screen supports characterization of the trajectory on the axis: l l l l start and stop frequency, acceleration, software hi limit, software lo limit.
The input area for trajectory characteristics is as follows.
Trajectory
Start/stop frequency
Acceleration
Software Hi Limit
Software Lo limit
100 Hertz
9 155 Hertz/s
10 000 000 pulses
-10 000 000 pulses
The table below describes the dialog box for inputting trajectory characteristics.
Field Description
Start/stop frequency Called SS_FREQ, this is the minimum speed of the movement of the moving part.
If FMAX, the maximum speed defined in configuration, is lower than 4
KHz, SS_FREQ must be contained between 0 and FMAX.
Otherwise, SS_FREQ must be contained between 0 and 4KHz.
When SS_FREQ is left at zero, the start and stop frequency is the smallest frequency in the range (See Configuring control parameters,
p. 62 ).
Acceleration Called ACC, this is the moving part’s acceleration and deceleration gradient or the period of acceleration needed to go from the speedSS_FREQ to FMAX (See Configuring control parameters, p.
62 ).
When the user-defined unit is Hertz/s, this parameter must be between the lower acceleration limit for the range of max speed and the acceleration entered in configuration (See
Description, p. 63 ).
When the user-defined unit is ms, this parameter must be between the value of the max acceleration entered at configuration and 5000 ms.

Software Hi Limit
Software Lo limit
Description
Called SLMAX and expressed by number of pulses, this is the maximum position of the movement of the moving part in the positive direction.
Called SLMIN and expressed by number of pulses, this is the minimum position of the movement of the moving part in the negative direction.
The software limits must respect the following differences: l l
SLMIN less than or equal to SLMAX
SLMIN and SLMAX between 16 777 216 and 16 777 215
When the two software limits SLMIN and SLMAX are zero, the monitoring of these software limits is not activated. Movements can be executed on the whole of the counting range from
-16 777 216 to + 16 777 215 without, however, exceeding one of these limits.
