2.4 Product Functions Describetion
3M2280N 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 settings
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 which
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.

Half current function: If the half current setting is effective. 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. Strongly recommended to use this function!!!

Test running: If the driver is set to this status, it will automatically drive the motor at a
speed of 60RPM. At this time, the output current is the set value and the subdivision
setting becomes invalid. This function is used to check whether the driver status is
normal.

PLS+DIR and CW/CCW compatible input: The control signal input port of the driver
supports “PLS + DIR” control signal and “CW/CCW” control signal input.

Over-voltage alarm: The driver will generate a high-voltage alarm if the internal bus
voltage exceeds 395 VDC. At this time, turn off the power supply in time and reboot
the driver to clear the alarm. If the over-voltage alarm occurs frequently, it is
recommended that the input voltage be tuned down or a driver with absorption function
be adopted.

Short circuit alarm: The driver will activate the short circuit protection function in the
case of short-circuit or wrong wiring of the motor or driver, so as to prevent the
damage to the driver. In this case, turn off the power supply in time and check the
wiring of the motor. To clear the alarm, reboot the driver.

Under-voltage alarm: The driver will generate a low-voltage alarm if the internal bus
voltage goes below 200 VDC in the case of the 2M2280N driver or 90VDC in the case
