SD266 Two-Phase Stepper Drive

SD266 is a compact size stepper motor drive with a wide DC input voltage range from 18~60VDC and 6A rate current. SD266 is a general purpose stepper motor drive suitable for various of applications. Specifications as below

*Low noise benefit from full micro-step smoothing technologies.

*Max input response frequency：140KHZ.

*Position memory function: SD266 can memorize the position of stepper motor when power is off. When power is restored SD266 can drive the motor to the memorized position where power was lost.

*Two LED lights. Power light will turn on when there is input voltage. Status light will flash when there is an alert. The number of the flash times indicates alert code.

*Output Current：0 ～ 6A（Peak). Adjustable with DIP switches.

*Auto-Half-Current function: Output current will anatomically reduced 50% when there’s no pulse input for a certain period.

*Micro-step:400 ～ 60000（pulse/turn).  Adjustable with DIP switches.

SD266 dimensions (mm):

SD266 can be used to drive NEMA8 (20mm), NEMA11(28mm），NEMA14(35mm），NEMA16(39mm)， NEMA17(42mm)， NEMA23(57mm) 2-phaspper motors from MOTEC with a holding torque range from 0.015 to 3N.m. It is recommended to use MOTEC 2-phase stepper motor with SD266 stepper drive however most 2-phase stepper motor on the market are compatible.
