5.5 Handwheel Measurement Conversion Coefficient P13
Description
5 - 12 en-938818/7
Category Measurements
Type 5 Unsigned decimal
No. of words 18
Moves the handwheel by an increment equivalent to the internal measurement unit (in manual mode).
Principle
Words N0 to N7
The first four pairs of words (N0 to N7) correspond to the values assigned to the handwheels. The first word of the
pair indicates the multiplier coefficient (MULTI) and the second the divider coefficient (DIVI).
The conversion formula is as follows:
Movement (internal measurement unit) = Encoder measurement (No. of lines) x Multi/Divi
Where Encoder measurement = Number of lines output by the encoder x 4.
Multi/Divi = Movement (internal measurement unit)/Number of encoder lines x 4
The internal measurement is expressed in mm/10, mm/100, μm, μm/10 or μm/100 for linear axes (see 4.8).
Words N8 and N9
These words define the measurement increment for the handwheel in automatic mode so that the increments related
to rotation of the handwheel are added to the increments computed by the CNC when preparatory function G12 is
enabled.
N8 contains MULTI.
N9 contains DIVI.
Words N10 to N17 (used with CNC software at index J)
When using rotary axes (modulo 360 and/or with limited excursion) driven by a handwheel, a second MULTI/DIVI pair
can be defined for each handwheel. This pair is automatically taken into account whenever the handwheel is used
to drive a rotary axis.
If these words are set to 0, the MULTI/DIVI values from words N0 to N7 are used regardless of whether the driven axis
is linear or rotary. N10 to N17 are initialised with default values of 0.
The conversion formula and other definitions remain the same.
