FMDD36D22NOM is a two-phase hybrid stepper motor driver based on DSP control, andit is a new generation of digital stepper motor driver. The driving voltage is DC12V~36Vsuitable for various types of two-phase hybrid stepping motors with a current below 2.2Aand an outer diameter of 39~42mm. Smooth operation, minimal vibration and noise.The positioning accuracy can reach up to 6400 steps/rev. This product is widely used inlaser processing equipment, medical equipment, measuring equipment, electronic

PRODUCT FEATURES

Equipped with 8 equal-angle and constant-torque subdivisions, the highestresolution is 6400 steps/rev

The highest response frequency can reach 200KppsOpto-isolated signal input/output

Drive current 0.3A/phase to 2.2A/phase adjustable in 8 steps

Automatic half current can be set by the user, when the stepping pulse stopsfor more than 1.5s, the coil current will be automatically reduced to half ofthe set current

Single power input, voltage range: DC12~36VThe supply voltage shouldn’ t exceed 36VDCInput control signal is 5V, and a current-limiting resistance is unnecessarywhen it isover 5V.

Input pulse signal is effective with the rising edge.

Alarm indicator ALM lights and the driver stops working when the driver tem-perature is over 80°C. It restarts working until the temperature falls to 50°C.The heat sink is needed when overheat occurs.

Alarm indicator ALM lights when overcurrent (short of load) occurs. Pleasecheck motor' s connection and other shorts and turn the power supply onafter removing the trouble.

Alarm indicator ALM lights when no motor connected or poor connection.Please check motor’ s connection and turn the power supply on after remov-ing the trouble.

APPLICATIONS

mainly used on automatic machines such as medical devices, dispenser, engravingachine, laser devices, lable machine, electronic device, advertisement devices, etc.it application performance perform excellent in user's expectation of low heat, lownoisy, now viabration, high stability, high precision
