User Manual
Note:
Blinking slowly means blinking at a frequency of 0.5 Hz, and blinking quickly means
blinking at a frequency of 5Hz.
To clear any alarm of the driver, it is necessary to disconnect the power supply and
then reboot the driver.
In the case of any alarm, it is necessary to disconnect the power supply in time, and
never touch the driver and motor when the power supply of the driver is on.
Except for the normal running, test running, and absorbing status, the driver ERR
signal will output a low level.
If any indication not covered in the above table occurs, please contact our customer
service personnel.
4.2 FAQ on the Driver and Stepper Motor
1. What is the maximum allowable surface temperature for a stepper motor?
The excessively high temperature will demagnetize the magnetic materials of a
stepper motor and as a result, cause lower torque or out of step of the motor.
Therefore, the maximum allowable surface temperature of a stepper motor depends
on the demagnetization point of different magnetic materials. In general, the
demagnetization point for magnetic materials is above 130℃, so it is normal if the
surface
temperature
of
a stepper motor remains at 80℃ - 90℃.
2. How to calculate output power of a stepper motor?
The output power of a stepper motor varies with the rotation speed and is generally
measured by torque. The calculation formula for output power of a stepper motor
is: P=ω*M; whereω=2π*n/60, ω indicates the angular speed and M indicates the
output torque.
3. What is the subdivision function of the driver intended for?
The subdivision function of a stepper motor driver is a kind of electronic damping
technology. It has three distinctive functions:
A. It enhances the control accuracy due to the subdivision of step angles.
B. Subdivision is the best method to suppress the low-frequency oscillation of the
motor. C. It can enhance the motor torque to some extent.
