- LV8729Type sub-type two-phase hybrid stepping motor drives, DC91-35V power supply for current less thanEqual to 1.5A, outer diameter less than 57 mm of two -phase hybrid stepping motor,As24,28,39,42Stepper motors , etc..
- This drive uses all-digital current loop subdivision control , small torque ripple of the motor, smooth running at low speed , low vibration and noise. When a relatively high -speed output torque , high positioning accuracy. Widely used in engraving machines, CNC machine tools, packaging machinery, transmission equipment and other requirements of the higher resolution devices.
Specifications:
- Using 6N137 high-speed optical coupling to ensure high speed without losing step
- Suitable 42,35,1.5 A within two / four-phase / four wire / six -wire stepper motor
- Segments: full step , half step , 1/4 step , step 1/ 8, 1 /16 step 1/32 step , 1/ 64, 1 /128 step up to 128 segments.
- Installation hole diameter : 3.5mm
Running current regulation
DIP switches S4, S5, S6 is used to adjustRunning current , DIP switch to ON = 1, and vice versa represents 0 .
When S4 = 0, S5 = 0, S6 = 1, set the operating current of 0.25A;
When S4 = 0, S5 = 1, S6 = 0, set the operating current of 0.45A;
When S4 = 0, S5 = 1, S6 = 1, set the operating current of 0.65A;
When S4 = 1, S5 = 0, S6 = 0, set the operating current of 0.85A;
When S4 = 1, S5 = 0, S6 = 1, set the operating current of 1.07A;
When S4 = 1, S5 = 1, S6 = 0, set the operating current of 1.27A;
When S4 = 1, S5 = 1, S6 = 1, set the operating current of 1.5A;
DIP switch to ON for 1, otherwise is 0 .
Automatic half current function
Within 0.5 seconds when no step pulse input , the motor current is automatically reduced by half, to reduce fever drives and motors , stepper pulse arrives again when the motor current immediately into the operating current mode ( full-flow mode )
Select subdivision
DIP switches S1, S2 and S3 models are used to select segments of eight kinds of segmentation models :
S1 = 0, S2 = 0, S3 = 0,1 subdivision ( full step )
S1 = 1, S2 = 0, S3 = 0,2 subdivision
S1 = 0, S2 = 1, S3 = 0,4Subdivision
S1 = 1, S2 = 1, S3 = 0,8Subdivision
S1 = 0, S2 = 0, S3 = 1,16Subdivision
S1 = 1, S2 = 0, S3 = 1,32Subdivision
S1 = 0, S2 = 1, S3 = 1,64Subdivision
S1 = 1, S2 = 1, S3 = 1,128Subdivision
Note: * DIP switch to ON said one , on the contrary represents 0
Attenuation adjustment (Decay)
LV8729 and THB7128 using the same technology automatically adjust attenuation , so the use of the driving motor relative to other chips have lower noise and vibration
