9 Drive Servo Start-Up Application(as from SW 3)

Introduction SW 3 / SW 4 provides support for drive start-up and diagnostics by means of the

following functions:

Description in section

Measurement of drive control loops (current, speed, position) 9.2

Function generator 9.3

DAC output

Mixed I/O output 9.4

Circularity test (SW 4 and higher)

Conventional quadrant error compensation (SW 2 and higher)

Neuronal quadrant error compensation (SW 4 and higher)

9.5

Trace function (user-parameterizable oscilloscope function – SW 4 9.6

Safety measures All measuring functions initiate traversing motions. It is therefore important to en-

sure that

Sthe EMERGENCY STOP switch is within reach

Sthe traversing range is free of obstacles.

Always enter the lowest possible traversing range limits. The measuring

function is aborted if the specified traversing range is exceeded.

For axes with an endless traversing range, the traversing range monitoring function

can be deactivated by entering “0” for the traversing range upper and lower limits.

The value 0.0 corresponds to zero traversing limits, i.e. the

traversing range is not monitored.

You can also end the movement by means of the

SNC STOP key

SSTOP softkey

SRESET key

or by cancelling the

Scontroller enabling command,

Sdrive enabling commands or

Straverse enabling command

Sfeed or spindle enabling command

or by setting the OVERRIDE switch to 0/50 for feed/main spindle drives.

Enabling commands There are three possible methods of enabling traversing motions; these can be

selected in the Enables toggle field:

Sinternally

SPLC

SPLC or NC (SW 4 and higher)
