Whether used as a stand-alone device or as expansion of an existing machine tool, SD2T by SIEB & MEYER offers
the perfect basis for driving synchronous and asynchronous spindles or motors with speeds up to 480,000 rpm.
All components necessary for the self suffi cient operation as for example operating and display elements as well
as motor chokes are already integrated in the device. Furthermore, SD2T can be connected to an existing machine
control via analog reference signals (+/-10 V), digital I/Os or USB. The low-voltage version of SD2T is equipped
with a galvanic separation of the power unit which protects the sensitive isolation of low-voltage motors.
The feature of saving up to 64 motor parameter sets in the drive enables the variable operation with different
motors. The devices in table top design are available as low-voltage version with output voltages up to 60 V and
as high-voltage version with output voltages up to 220 V.
