6.1.7 Spindle C Axis Adjustment (For Lathe System)

(1) Setting the gain

For spindle C axis speed loop gain, SP008 (speed loop gain 2), speed loop gain set 2, which consists of SP009

(speed loop lead compensation 2), and SP010 (speed loop delay compensation 2), is used. Thus, SP035 has to be

set as follows. For position loop gain, set standard 33 to SP002 (position loop gain, interpolation mode).

< Related servo parameters >

Set the spindle and interpolation axis.

(2) Gain adjustment and accuracy test during C axis operation

Set the "Time-series data measurement" with NC Analyzer as follows during stopped in C axis mode (servo

ON status) or when executing cutting feed with G01 F20. Then check the droop fluctuation is within 10°/1000.

SP005 setting value set in "Basic Adjustments" (Initial setting value: 150)

0200: Speed loop gain set 2 selection (validate bit9)

Set the same value as spindle parameter "SP002"

Set it when using SHG control (when not using, set to "0")
