6) Duration of the End of Positioning output enabling (Cutting time)  

//

//

//

At the end of positioning, the 

END OF POSITIONING 

output is enabled for a time that can be set from  100 to

9999 milliseconds; by setting  0  the End of Positioning output remains enabled until the next start
command is given.

It determines the enabling time of the AUX output that can be set from  100 to 9999 milliseconds (see

With this constant it is possible to set the enabling of the

By setting a value other than zero the enabling to the clearances recovery in the onward positioning is
obtained: that is the same axis exceeds the positioning dimension of one value amounting to the set
Clearances Recovery Dimension and then waits for a time equal to the Motion Reversing Time to go back
to the target dimension.

In order to avoid excessive strain on the handling system, it is possible to set a waiting time, ranging
between 0 and 9999 milliseconds, for all the motion reversing manoeuvres.

11) Deviation dimension  

-/

-/

-/

By setting this constant to a value differing from zero, at the end of the positioning the instrument waits for
the switchover from open to closed of the  

WORK COUNTER 

input to carry out an onward shifting of a

dimension equal to the Deviation Dimension; after that, when a time equal to the Deviation Return Waiting
Time has elapsed, the instrument returns to the set dimension.
If a Deviation Dimension equal to zero is set this function is disabled.

12) Deviation Dimension Waiting Time

Time interval after which the return from the deviation dimension is obtained (active only if a Deviation
Dimension other from zero is set); it can be set between 0 and 9999 milliseconds.

13) Displayed value for an encoder turn  

 

 

 

 

The instrument can correct counted pulses by multiplying them by a coefficient amounting to the ratio
between the 

 

  

and 

 

 

 

constants; if the two constants are opportunely set it is possible to

display the wished value for a given number of pulses counted on inputs.  The value to be set in this
parameter represents the value to be displayed connected to an encoder turn, that is the multiplier factor
of input pulses.
The range of admissible values is  0 

÷

 999999.

14)

 

Number of pulses for encoder turn 

 

 

 

 

The value to be set in this parameter represents the number of pulses for a turn of the encoder that is the
divisor factor of input pulses.
The range of admitted values  is  0 

÷

 999999.

Example:
Let us consider a 100 pulses/turn encoder and for every turn an axis shifting of 123,4567. In order to
display the value of 123,45: set 

 

=12345 and
