AP.3.2 GEAR RATIOS

The gear ratios consist of parameters NP121, NP122 and NP123 only.

These parameters indicate the mechanical transmission ratio between the motor and the axis

ballscrew or between the motor and the tool in the spindle. NP123 indicates the pitch of the

ballscrew.

Axes:

These parameters must be set for each Gear Ration and change the Active Ratio with

each gear change.

Spindle:

These NP parameters must be updated for each change of Gear only when working in

SERCOSLE=1 mode and if we want to display the spindle speed on the CNC screen or

work in M19 mode or in Rigid Tapping.

In those cases, the mechanical maneuver in the machine gear box will be accompanied by a

change of Active Gear Ratio

The command to change gears is given through the Sercos interface. This change

cannot be handled through digital inputs.

Operation status:

Parameter GP6 sets the number of useful gear ratios (1

GP6

8).

Variable GV25 informs which is the current (actual) gear ratio (0

GV25

GP6).

Variable GV26 registers the preselected Gear Ratio
