AMCI Model: #SD17040B

The SD17040B is AMCI's newest 4Arms stepper motor driver. It has the same performance and features as AMCI's former model #SD17040 but at a lower cost, and is recommended for all new designs. A narrower, more compact design retains a versatile mounting pattern, while saving valuable mounting space. Additionally, improvements to the drive eliminate the finned heat sink permitting panel or side mounting.

The SD17040B 4.0 Amp stepper motor driver is a self-contained stepper motor drive with its own power supply, full and half step sequencer, two switching amplifiers, and opto-isolation circuits. Plus, it has the ability to interface to any controller that produces Step and Direction or CW/CCW pulses. The inputs accept differential line driver signals or can be connected to transistor type outputs with the use of current limiting resistors.

The SD17040B also has Idle Current Reduction circuitry that allows it to automatically reduce the motor current when the motor is not turning.

Phase current, full or half step motion, and idle current level are all selected by a series of DIP switches accessible on the top of the SD17040B.

The SD17040B will interface with AMCI's NEMA 23 and NEMA 34 stepper motors. These motors have been tested and selected to perfectly match the electrical requirements of the SD17040B.

AMCI SD17040B will work with any controller/indexer that generates Step and Direction or CW/CCW pulses. The SD17040B-24 will work directly with controllers that have a Pulse Train Output (PTO) function that operates at 24Vdc. SLC500: Allen-Bradley 1746-HSTP1 Stepper Controller for SLC500.
