TDA 1
The main spindle controller TDA 1 is dedicated to the intelligent digital
control of INDRAMAT asynchronous main spindle motors 2AD and
frameless spindle motors 1MB with a continuous power rating of 3 to 10
kW at the motor shaft.
DrivesequippedwiththecontrollerTDA1aredistinguishedbytheirhigh
stiffnessandawidespeedrangeatconstantpower.Theyare,therefore,
particularly suited for use as a main spindle drive on numerically
controlled machine tool centres.
Besidesits wide speedrange, an a.c.main spindledrivewith TDA1has
an integral position control circuit capable of automatically positioning
thespindle (e.g.,for workpiecechange) witha maximumresolution of1/
4 000 000 revolutions in response to a signal. The internal controller
positionloopisclosedeitherbythemotorfeedbacksignal(fordirectdrive
or gear ratio 1:1) or by an additional, optional spindle feedback signal
(switchable gear, belt-driven gears).

The TDA 1 operates in conjunction with other controllers for feed axes.
Acombinationofpowersupplymodule,modularmainspindleandservo
drive controllers permits individual matching of the drive to the task of a
CNC machine tool.

The a.c. main spindle drive with TDA 1 is also capable of operating the
spindle as a servo axis (C-axis) with a high-accuracy position control
loop. The main spindle motor is fitted with a high-resolution motor
feedbackdevicetocopewiththelowspeedsrequiredinthisapplication.
The controller detects the rotor position with a maximum resolution of 1/
2 000 000 revolutions, thus allowing even the lowest speeds to be
precisely controlled.
Since the spindle operates as an interpolating axis in C-axis mode and
the NC controls require information on the spindle position, the TDA 1
supplies compatible position signals for incremental encoders through
an optional output. The increments are derived either from the high-
resolution motor feedback device or from an additional, optional spindle
feedback device. The spindle feedback, in the latter case, is a high-
