Application:
YKA2811MA
is a constant torque driver with microstep, the upmost microstep amounts to
200, voltage range from AC60V-AC130V,can match two phase hybrid step motors
which rated current under 8A, flange size range from 86~130mm.
YKA2811MA
is A new generation of 32-bit DSP technology based on high-performance stepper
driver, driving voltage AC60-110V,suitable current below 8.0A, diameter
86mm-130mm of various types of two-phase hybrid stepper motor.The driver in the
internal use of similar servo control principle, unique circuit design,
superior software algorithm processing, so that the motor in the running
stability, noise, vibration and other performance has superior
performance;Smooth and accurate current control technology greatly reduces
motor heat;External 16-grade constant torque subdivision with equal Angle, up
to 125 subdivision;Optocoupler isolates differential signal input, strong
anti-interference ability;With over-voltage, under-voltage, over-current protection
and other error protection functions;With super - stability, low vibration, low
noise superior performance in one.
feature:
Low noise, excellent stability
16-speed constant angle constant torque stepper motor
Adopt a unique control circuit, effectively reduce noise and increase rotation
stability
Maximum response frequency up to 200Kpps
When the pulse stops for more than 100ms, the coil current is automatically
reduced to 20%-80%
Bipolar constant current chopping mode, so that the same motor can output more
speed and power
Optically isolated signal input/output
Drive current from 0.5A/phase to 8.0A/phase separation speed adjustable 16
Single power supply input voltage range: AC60-130V
Error protection: thermal protection; over-current, low-voltage protection
Typical
applications: CNC machine tools, engraving machines, packaging equipment,
woodworking machinery, laser cutting machine,textile equipment, ceramic
equipment, electronic equipment constant speed applications
Equal Angle constant torque
subdivision
With
16 levels of constant torque subdivision, the drive current from 0.5A/ phase to
8.0A/ phase can be adjusted in 16 levels
Large torque lift
Bipolar
constant current chopper mode allows the same motor to output greater speed and
power
Its low heat dissipation
ability is strong
The
control circuit is used to effectively reduce the noise and increase the
rotational stability. When the stepping pulse stops over 100ms, the coil
current is automatically reduced to 20%-80% and the heat of the driver is
reduced by 50%
