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.
Drives equipped with the controller TDA 1 are distinguished by their high
stiffness and a wide speed range at constant power. They are, therefore,
particularly suited for use as a main spindle drive on numerically
controlled machine tool centres.
Besides its wide speed range, an a.c. main spindle drive with TDA 1 has
an integral position control circuit capable of automatically positioning
the spindle (e.g., for workpiece change) with a maximum resolution of 1/
4 000 000 revolutions in response to a signal. The internal controller
position loop is closed either by the motor feedback signal (for direct drive
or gear ratio 1:1) or by an additional, optional spindle feedback signal
(switchable gear, belt-driven gears).
