FANUC Series 30i/31i/32i-MODEL B FANUC Series 0i-MODEL F

Overview

In FSSB high-speed rigid tapping, pairs of servo axes that synchronize to each spindle axis are extended from four pairs to eight pairs.

Details

In FSSB high-speed rigid tapping, pairs of servo axes that synchronize to each spindle axis are set by parameter (No.24204). Conventionally, the parameters can be set up to four pairs, but in this extension, the parameters can be set up to eight pairs. Thereby, FSSB high-speed rigid tapping can be used by more servo axes.

[Example of parameter setting]

When the parameter FHR (Bit 0 of No.24203) is set to 1, FSSB high-speed rigid tapping is enabled.
And, the index number of the spindle axis that synchronizes with the servo axis used by FSSB high-speed rigid tapping is set to the parameter (No.24204) as follows.

Path 1

Path 2

In addition, set 1 to the parameters FHRSV (bit 1 of No.2429) and FEED (bit 1 of No.2005) of Z1 and Z2 axes and the parameter FHRSP (bit1 of No.4549) of S1 and S2 spindle axes.
Eight or less index numbers of the spindle axis can be set in all system. If nine or more index numbers of the spindle axis or illegal index number of the spindle axis is set, the alarm (PW0037) “SV/SP COMBINATION ERROR” is issued.
