2.4 Product Features
High performance, low cost, and diversified functions.
2M2280N adopts 187V~253V wide-range power supply and can be connected directly
with single-phase 220V AC power to save the cost of a transformer.
Automatic parameter adjustable regulation.
Supporting driver test running function.
Supporting phase memory function.
Supporting PLS+DIR and CW/CCW control signal.
Supporting optocoupler isolation ERR signal output function and interaction with the
upper computer.
Output current of the driver automatically reduces by a half in 1.5S after the driver gets
static
Opto-isolation signal input, with pulse response frequency up to 400 KHz.
Simple and easy subdivision and current setting.
12 micro-step value, the maximum micro-step value is 128.
With the protection function of over-voltage, under-voltage, over-current, overheat.
With micro-step smoothing filter, the input pulse can be dynamically smooth and
reduce the transient motor sport, motor run more smoothly.
2.5 Product Functions
2M2280N stepper motor drivers adopt DSP single-chip microcomputer as its control core,
which greatly enriches their applications. Meanwhile, the intelligent firmware design frees
the users from complicated function setting steps and delivers the optimum performance
of the motors easily.
Motor auto adaptation: The driver can automatically detect the
electrical
parameters
(e.g., inductance and resistance) of the motor connected with the driver, trace the
status of motor in real time, and automatically adjust the driver parameters
according to the detected motor status to deliver the optimum driving performance.
If it is not the first time for the driver to drive the motor, please run the driver under
no load before connecting the motor. Then, the driver will clear the motor
parameters stored before. Turn off the power, connect the motor, and turn on the
power again; the driver will automatically detect the optimum drive parameters for
the current motor.
Phase memory: The driver will keep the phase of the motor in the case
of
power
failure with the motor. Therefore, it prevents the error caused by motor jitter upon
power-on on some application occasions. The kept phase will be lost if the motor is
replaced or the motor still rotates after the driver stops.
Automatic half current: After the motor stops rotation and locks tight, the driver
will
reduce the phase current of the motor by a half in 1.5 seconds to cut down the
heat generated by the motor, theoretically, by 25%.
Test running: If the driver If the driver is set to this status, it will autoatically drive
